Installation

4.2Mounting keypads

Security Command keypads have removable covers that allow you to easily mount the base to a wall or other flat surface using the screw holes provided on each corner.

For mounting keypads on solid walls, or for applications where conduit is required, use a DMP 695, 696, 775, or 776 keypad conduit backbox.

4.3Wiring keypads

Keypad data bus

The keypad data bus consists of a 4-wire cable that provides 12 VDC power, data in, data out, and a panel common. You can connect keypads in parallel on one 4-wire cable or provide a separate cable run back to the panel for each keypad. The maximum cable length for one keypad can be up to 500 feet using 22 gauge wire or up to 1000 feet using 18 gauge wire. Additional keypads installed on the same cable decrease the maximum distance at which they'll operate properly.

Refer to the 710 Bus Splitter/Repeater Module Installation Sheet (LT-0310) for additional information when connecting keypads to a keypad bus circuit greater than 2,500 feet.

Primary Power Supply

5.1AC terminals 1 and 2

Connect the transformer wires to terminals 1 and 2 on the panel. Use no more than 70 ft. of 16 gauge, or 40 ft. of 18 gauge, wire between the transformer and the XR6A/XR10A/XR20A.

Always ground the panel before applying power to any devices: The XR6A/XR10A/XR20A must be properly grounded before connecting any devices or applying power to the panel. Proper grounding protects against Electrostatic Discharge (ESD) that can damage system components. See Earth ground, section 6.2.

5.2Transformer types

The larger transformer for the XR6A/XR10A/XR20A is 16.5 VAC 40VA, which provides up to 1.5 Amps of bell output current, 500mA of auxiliary current, and 100mA of smoke detector output. The total current available is limited by the total battery standby requirements of the installation. When a 16.5 VAC 20VA plug-in transformer is used, the bell output current is reduced to 600mA.

The transformer must be connected to a commercial power outlet that is not controlled by a wall switch. Never share the transformer output with any other equipment.
