LiftMaster CAPXM Manual Overview

The LiftMaster CAPXM Smart Video Intercom M (Model CAPXM, branded "myQ Business Smart Video Intercom M" on the manual's cover) is, in LiftMaster's words, a cloud based access control solution that includes an integrated video camera enabling advanced video features. It has a touchscreen display, speaker, microphone, and camera, a control board, and a door board that can control up to two access points (doors or gates), each with a primary relay, an auxiliary relay, a Wiegand input, a request-to-exit input, and a status (supervised) input. It also has a built-in LiftMaster Passport receiver (Security+ 2.0) that can communicate wirelessly with compatible gate operators.

LiftMaster's manual is organized in four parts after the introduction: (1) pre-install (myQ Business account), (2) install (knockouts, mounting, ground, power), (3) network, and (4) access control (gate and door wiring, RFID reader, Wiegand output, postal lock, wiring diagram, parts, accessories). This page follows the same order. The manual has no troubleshooting chart or diagnostic code table, so this page has none; see the Control Board Overview for the diagnostic LEDs LiftMaster labels.

Control Board Overview

LiftMaster's overview illustration of the control board (page 5, front and back views) labels these items; the illustration is not reproduced here.

  • Connections: power (+ and -), expansion, Wi-Fi antenna connection, speaker, microphone, touch panel, display data, Security+ 2.0 radio antenna, USB Ethernet, USB (camera), postal lock, and door board.
  • Switches and diagnostic LEDs: voltage input, admin mode (switch #1; see Connect Internet), not used, +12 volts, +5 volts, +3.3 volts, +3.4 volts, and diagnostic.

LiftMaster's notes: main power supply and control wiring MUST be run in separate conduits. Conduits must be UL approved for low and high voltage. Refer to the NEC for additional wiring requirements. Category 5e cabling is the minimum performance category recommended. Wiring shall be in accordance with the National Electrical Code (ANSI/NFPA 70), local codes, and authorities having jurisdiction.

Always provide power from a dedicated source. Plug the provided transformer into an outlet wired to its own 10 Amp minimum circuit breaker. This prevents two problems: other equipment cannot introduce spikes, noise, surges, or dips into the power circuit that will affect the system, and the system's operation will not be affected if other equipment develops a short circuit across the power line.

*CAT 5/6 network cable notes: for outdoor distances exceeding 140 feet (42.7 m), a UL497 compliant primary surge protector MUST be installed at the CAPXM. Distances exceeding 328 feet (100 m) may be accommodated with additional hardware (available through third-party sources).

Internet Requirements

When selecting a router, use the following information to ensure compatibility (page 10). The CAPXM can be connected to a router through a wired connection or Wi-Fi. LiftMaster recommends a minimum upload/download speed of 5 Mbps for each CAPXM supporting video camera feeds. This upload speed should be met when considering the use of other devices on the network, like cameras and computers.

  • Wi-Fi security compatibility: WPA3 Personal and WPA2 Personal (AES).
  • Wi-Fi protocols: 802.11b, 802.11g, and 802.11n @ 2.4 GHz.
  • Wi-Fi extenders: DO NOT use Wi-Fi extender devices. They may introduce latency in the connection, leading to choppy or lost video transmission.
  • Signal strength: if using a Wi-Fi signal strength tool or app, a continuous Wi-Fi signal strength of at least -65 dBm (numbers closer to zero are stronger) at the CAPXM must be guaranteed to ensure an acceptable connection to the local network. When checking signal strength in CAPXM admin mode, LiftMaster recommends at least two bars, as shown on the CAPXM screen.
  • If two bars are not available: relocate the router or the antenna, or use accessory WFAEXT (Wi-Fi Antenna Extension Kit, 15 ft) to move the CAPXM antenna higher up or to a location resulting in two or more bars.
  • Hidden networks: hidden network SSIDs are not supported. The network must be selectable from the CAPXM display.
  • Secondary authentication: Wi-Fi networks requiring secondary authentication are not supported (for example, hotel and airport Wi-Fi).

LiftMaster CAPXM Installation

LiftMaster's installation steps are: Step 1, remove knockouts; Step 2, mount the CAPXM; Step 3, install the ground; Step 4, connect power. Network setup then follows (connect internet and validate setup), and then the access control wiring.

Remove Knockouts (Step 1)

To prevent damage to the CAPXM from moisture or water:

  • DO NOT install during rain. Internal components MUST be kept free of water and moisture.
  • BEFORE opening the front cover of the CAPXM, remove ANY accumulated water from the top of the CAPXM.

To prevent damage to ANY internal components: DO NOT attempt to remove the knockouts with a hammer. Banging on the knockouts may result in shock to the circuit boards, which could cause permanent damage.

Step 1, remove knockouts

  1. Prepare the work surface by laying down a cloth or other protective material.
  2. Lay the CAPXM face down on the protective material.
  3. Identify which knockouts need to be removed based on your application.
  4. Use a center punch tool to remove the knockouts from the outside of the box inward using an appropriately sized punch and hammer. Be careful when removing the knockouts to avoid damaging the CAPXM components.

LiftMaster's illustration marks each knockout with a letter: E = electrical wiring, P = pedestal mount, R = recess/surface mount, S = Security+ 2.0 radio antenna, and W = Wi-Fi antenna.

Mount the CAPXM (Step 2)

Step 2, mount the CAPXM

  1. Attach the goose-neck gasket (provided) if mounting to a goose-neck.
  2. Mount the CAPXM securely to a flat surface or pedestal with appropriate 1/4 in. hardware, taking care to route wiring through the appropriate knockouts. Stainless steel hardware is recommended. Use of zinc plated or galvanized hardware is at risk for galvanic corrosion.
  • Cover clearance: ensure the cover can fully open to allow access after the installation is complete. Allow 1/8 in. (3.175 mm) of space between the bottom of the CAPXM and the wall if flush-mounting the CAPXM without the trim kit.
  • ADA compliance: when mounting the CAPXM at a pedestrian entrance, to meet ADA compliance, mount the top of the CAPXM screen no higher than 54 inches from the ground.
  • Sealing: make sure the CAPXM is properly sealed to prevent damage from moisture.

LiftMaster's illustrations show a pedestal mount and a surface mount.

Install the Ground (Step 3)

Important (LiftMaster): an earth ground rod is strongly recommended and should be no further than 12 feet (3.7 m) from the CAPXM, using a minimum of 12 gauge wire in most cases. The type and length of earth ground rods vary by region. Contact the AHJ (Authority Having Jurisdiction) in the municipality where you plan to install the CAPXM for correct grounding materials and installation procedures. A proper ground is critical to minimizing the risk of damage to the CAPXM from electrical transients.

Step 3, install the ground

  1. Connect the ground wire (12 AWG or larger) to the CAPXM main earth ground connection.
  2. Run the wire from the CAPXM to a suitable earth ground.

Note: shield connections on boards should not be connected to the main earth ground connection. Keep the ground wire as straight as possible, and check national and local codes for the proper depth. To AVOID damaging gas, power, or other underground utility lines, contact underground utility locating companies BEFORE digging.

LiftMaster's illustration shows 12 AWG minimum ground wire to an earth ground rod, with other ground sources within 12 feet of the access control panel (the existing electrical system ground, or a metallic cold water pipe) and a maximum of 12 feet (3.7 m).

Connect Power (Step 4)

  • DO NOT use ANY power supply other than those supplied with your CAPXM.
  • DO NOT power electronic strikes and latches with the same power supply used to power the access control panel; doing so will cause DAMAGE to the CAPXM. Use ONLY a UL listed burglar alarm or access control system to power electronic strikes and latches.
  • DO NOT connect the power supply to a switched outlet or otherwise controlled AC outlet.
  • DO NOT connect the power supply to the 120 Vac outlet until ALL wiring is completed.
  • Install the transient noise suppression device (MOV) supplied with the CAPXM for AC powered devices, and a diode for DC powered devices.
  • DISCONNECT the power supply from the 120 Vac outlet prior to removing or attaching the terminal block to the control board.

The outlet for the CAPXM MUST be an external dedicated 120 Vac outlet, wired back to its own 10 Amp minimum circuit breaker. Maximum wire run distances for the power wiring:

Swipe sideways to see all columns.

CAPXM power wire run (page 15)
Wire specification Maximum run distance
14 AWG Up to 300 feet (91.4 m)
16 AWG Up to 200 feet (60.9 m)
18 AWG Up to 100 feet (30.4 m)

Step 4, connect power

  1. Connect 14-18 AWG wire to the stripped secondary DC output wires on the power supply. Black is negative and red is positive.
  2. Remove the PWR INPUT terminal block from the control board.
  3. Connect the power supply wires to the PWR INPUT terminal block (red to +24V and black to GND). Reattach the terminal block to the control board.
  4. Plug the power supply into a 120 Vac outlet after all connections have been made.
  5. Close the CAPXM door.

Note: the green LED on the door board will blink and the green LEDs on the control board will light solid when powered up. The CAPXM will display the LiftMaster logo while booting up. When boot up is complete, the user interface will appear.

If the power supply is installed outdoors, it must have its own approved NEMA 4 rated weatherproof electrical enclosure. Use conduit from the power supply enclosure to the controller enclosure.

Connect Internet (Network Step 1)

The CAPXM can connect to the internet with a wired connection or with Wi-Fi (wireless); see Internet Requirements. Make sure you are in Admin Mode before you connect to the internet. If you are not in Admin Mode, flip switch #1 to the ON position on the control board, press the Network tab on the CAPXM display, and press the "Change Network Settings" button. Follow the instructions for your application.

Option 1, wired connection

The Local Area Network (LAN) port is a 10/100 Ethernet interface with an RJ45 jack for connecting the CAPXM to a hub, switch, or router so it can gain internet connectivity. Use a straight (non-crossover) Cat5e or Cat6 cable, referred to as an Ethernet cable in the manual.

  1. Connect an Ethernet cable from the hub, switch, or router to the LAN port on the control board. When connected properly, the green and amber LEDs on the Ethernet port of the control board will light or flicker (the control board is located on the back of the CAPXM display). If the green LED is not lit, check the connections on the CAPXM and the Ethernet hub.
  2. On the display, select Wired Network if dynamic configuration (DHCP) is desired, or select Manual Setup for a static IP address.

Option 2, connect through Wi-Fi (wireless)

  1. On the display, select Wi-Fi Network.
  2. Select the network the CAPXM will use.
  3. Enter the password for the network.
  4. Select Login.

Additional compatibility considerations (LiftMaster): when checking signal strength in CAPXM admin mode, LiftMaster recommends at least two bars. If two bars are not available, relocate the router or the antenna, or use accessory WFAEXT (Wi-Fi Antenna Extension Kit, 15 ft). If using a Wi-Fi signal strength tool or app, a continuous signal strength of at least -65 dBm at the CAPXM must be guaranteed. Hidden network SSIDs and networks requiring secondary authentication are not supported.

LiftMaster's illustration labels the Ethernet path (LAN on the control board, router/switch, modem, Ethernet cable, 325 feet [99.1 m] maximum) and a Wi-Fi signal graphic with three ranges: -30 to -67 dBm GOOD, -66 to -85 dBm POSSIBLE, and "-86 dBm or weaker" POOR (printed as "≥ -86 dBm").

Documentation note. The manual gives two different maximum Ethernet cable lengths: 328 feet (100 m) in the wire specifications (page 9) and 325 feet (99.1 m) in the Connect Internet illustration (page 16). The text also requires a continuous signal of at least -65 dBm (pages 10 and 16), while the signal graphic shows GOOD as -30 to -67 dBm and POSSIBLE as -66 to -85 dBm, and prints the POOR range with a "≥" sign ("≥ -86 dBm") although weaker signals have more negative numbers. Treat the stronger requirement as the safer target and confirm with LiftMaster if your installation is near these limits.

Validate Setup (Network Step 2)

On the display, select each tab in Admin Mode to validate the setup (network, inputs, outputs, and so on). Once you have validated the setup, exit Admin Mode.

CAPXM Access Control Wiring

LiftMaster's manual shows wiring examples for gate access (wired, page 17), gate access (wireless, page 18), door access (page 19), an RFID reader (page 20), a Wiegand output (page 21), and a postal lock (page 21), plus a wiring diagram of the CAPXM's internal connections (page 22). All wiring pages say to disconnect power BEFORE making electrical connections. The diagrams are not reproduced on this page; use the original manual pages for terminal-level connections, and the notes below, which LiftMaster prints on the diagrams.

  • Disconnect power BEFORE making electrical connections.
  • DO NOT run high voltage power within the CAPXM enclosure.
  • DO NOT INSTALL THE SYSTEM IN THE FAIL SECURE MODE UNLESS PERMITTED BY THE LOCAL AUTHORITY HAVING JURISDICTION. Doing so may cause interference with the operation of panic hardware.

Gate Access, Wired (Page 17)

Gate access can be wired to Door 1 or Door 2 on the door board. LiftMaster Security+ 2.0 gate operators can also be programmed to communicate wirelessly instead of using a wired connection (see Gate Access, Wireless). The labels on LiftMaster's example include: push button, gate operator, maglock, reader or keypad (12Vdc red, ground black, DATA 0 green, DATA 1 white, green LED orange, red LED brown), external free exit loop detector, request to exit, status (supervised, with an end-of-line resistor), primary relay, auxiliary relay (alarm bypass, light), and an RFID antenna with Wiegand output.

  • Gate operator connection: connect to the gate operator's auxiliary closed limit switch; refer to the gate operator manual. The status (supervised) connection is not applicable for wireless gate operator connections.
  • Maglock: use 18-22 AWG wire and a separate power supply (not provided). DO NOT use the controller's power supply. For DC power, install a 1N4005 diode or equivalent. For AC power, install a Siemens S10K30MOV (metal oxide varistor) (provided) or equivalent.
  • End-of-line resistor: 1k ohm.
  • RFID antenna: power it separately (power not provided); DO NOT use the controller's power supply.
  • Wiring: keep the length of unshielded wires to a minimum to avoid electrical noise. For a KPR2000 keypad, wire the pink and black (ground) wires together.
  • Light or load on the auxiliary relay: the diagram's labels include an isolation relay, a low voltage power supply, and the load, line, and neutral connections.
  • UL evaluation: the maglock and alarm bypass were not evaluated by UL.

CAPXM Warranty

Per LiftMaster's warranty (page 26), LiftMaster ("Seller") warrants to the first purchaser of the product, for the structure in which it is originally installed, that it is free from defects in materials and workmanship for a period of two years from the date of purchase. Proper operation depends on complying with the instructions for installation, operation, maintenance, and testing; failure to comply strictly with those instructions will void the limited warranty in its entirety.

If, during the warranty period, the product appears to contain a covered defect, LiftMaster says to call 1-800-528-2806 before dismantling the product, then send it, pre-paid and insured, to its service center for warranty replacement. The warranty does not cover non-defect damage, damage caused by improper installation, operation, or care, labor charges for reinstalling a repaired or replaced unit, problems related to interference, or replacement of batteries, and it limits liability as stated in the full text. The complete terms are printed on page 26 of the manual.

Documentation note. The English warranty gives the number 1-800-528-2806, while the French version of the same manual prints 1 800 528 9131 for the same instruction. Confirm the current warranty phone number with LiftMaster before calling.

Frequently Asked Questions About the LiftMaster CAPXM

How many doors or gates can one CAPXM control?

Up to two access points (Door 1 and Door 2 on the door board), each with a primary relay, an auxiliary relay, a Wiegand input, a request-to-exit input, and a status input (page 6). It can also pair wirelessly with up to 4 gate operators, one for each primary and auxiliary relay (page 18). For a single access point, LiftMaster's CAPXS is the smaller model; see Related LiftMaster Resources.

What does the CAPXM need to work?

Per the manual: a myQ Business account with a service subscription (page 11), the supplied 24VDC power supply on a dedicated 120 Vac outlet (page 15), an internet connection by Ethernet or Wi-Fi with at least 5 Mbps upload and download per CAPXM that supports video (page 10), and a SIP account through Phone.com for the calling function (page 11).

How do I enter Admin Mode?

Flip switch #1 on the control board to the ON position (pages 16 and 18). For a new installation, press the login button without entering anything in the Admin Username and Admin Password fields (page 18). See Connect Internet.

What Wi-Fi does the CAPXM support?

802.11b/g/n at 2.4 GHz with WPA3 Personal or WPA2 Personal (AES), up to 250 feet open air. It does not support Wi-Fi extenders, hidden SSIDs, or networks that require secondary authentication such as hotel or airport Wi-Fi. If you cannot get two bars, relocate the router or antenna or use the WFAEXT antenna extension (pages 8, 10, and 16). See Internet Requirements.

Which gate operators can the CAPXM talk to wirelessly?

LiftMaster Security+ 2.0 gate operators, 2018 LiftMaster gate operators (firmware v4.4 and later), and HD operators (firmware v3.3 or later), up to 750 feet open air. It is not compatible with LiftMaster barrier gate operators, and wireless linking needs the optional Passport antenna kit (pages 8 and 18). See Gate Access, Wireless.

How far can I run the power wire?

Up to 300 feet with 14 AWG, 200 feet with 16 AWG, and 100 feet with 18 AWG (page 15). See Connect Power.

What ground does the CAPXM need?

LiftMaster strongly recommends an earth ground rod no more than 12 feet (3.7 m) from the CAPXM, with at least 12 AWG wire (page 14). See Install the Ground.

Which Wiegand formats does the CAPXM accept?

26-bit, 30-bit, 32-bit MiFare, and 37-bit with and without facility code, plus ASCII for keypads; only the 26-bit protocol is compatible in UL installations (pages 6 and 8). The CAPXM also has a 26-bit Wiegand output for third party access systems (page 21).

How high should I mount the CAPXM?

At a pedestrian entrance, to meet ADA compliance, mount the top of the screen no higher than 54 inches from the ground (page 13). See Mount the CAPXM.

Can I power a maglock or door strike from the CAPXM power supply?

No. LiftMaster says not to use the controller's power supply for the maglock, and to use only a UL listed burglar alarm or access control system to power electronic strikes and latches (pages 15, 17, and 19).

What warranty does the CAPXM have?

LiftMaster's limited warranty is two years from the date of purchase. See CAPXM Warranty and page 26 of the manual.

Does the manual come in other languages?

Yes. LiftMaster's combined PDF has the English manual first (pages 1 to 26), followed by French and Spanish versions. This page presents the English version.
