All DMP keypad housings are designed to easily install on any desk stand, 4” square box, 3-gang switch 

box, or a flat surface.  

The keypad housing is made up of two parts: the front, which contains the circuit board and keyboard 

components and the base.  Use the following steps and figures to separate the keypad front and base.  

1.  Insert a flat screwdriver into one of the slots on the bottom of the keypad and gently lift the 

screwdriver handle toward you while pulling the halves apart.  Repeat with the other slot.  

2.  Using  your  hands,  gently  separate  the  front  from  the  base  and  set  the  front  and  components 

aside.

Locate the keypad near a wall outlet for the Model 371-500 plug-in DC power supply.  In addition to 

powering the keypad, the power supply also charges the back-up battery. The plug-in power supply 

should be located within 100 feet of the keypad using 22 AWG wire or 250 feet using 18 AWG wire.  Use 

the following steps to connect the plug-in power supply:

1.  Connect the plug-in power supply Black wire with White stripe (positive) to the White wire of the included 4-wire 

harness.

2.  Connect the plug-in power supply solid Black wire (negative) 

to the Black wire of the wire harness.

3.  Plug the 2-wire harness on to the header on the back of the 

keypad. 

4.  Plug the power supply into a 110 Volt AC outlet not controlled 

by a switch.

The keypad rechargeable battery is used to provide 24 hours 

of backup battery power when DC power is not available.  The 

battery is intended for backup power only and not to operate the 

keypad on a daily basis.  If the battery is low, or not plugged into 

the J1 battery connector, a low battery condition is indicated by 

the XTL panel.  Use the following steps to replace the standby 

battery.  DMP recommends replacing the battery every 3 years 

under normal use.
Note:  If removing the keypad from service, disconnect the 4-wire 

harness from the back of the keypad.

1.  Disconnect the 2-wire harness from the back of the keypad.
2.  Remove the base.
3.  Loosen the top keypad PCB snaps.
4.  Lean the keypad PCB backwards and lift out from the bottom 

PCB snaps.
