Keypad Installation Instructions

Connecting the Keypads

The keypads are connected to the control panel's Digiplex bus in a star and/or daisy chain configuration. Connect the four terminals labeled red, black, green and

yellow of each keypad to the corresponding terminals on the control panel.

Connecting Keypad Zones

Each keypad has one hardwired input terminal, allowing you to connect one detector or door contact directly to it. Connect the device to the keypad's input

terminal as shown in Figure 5 on page 10. In order to communicate its status to the control panel, the keypad's input must be assigned to a zone in the control panel

and the zone's parameters must be defined.

Programmable Output

Each keypad has one on-board PGM. Upon activation, the PGM can provide 50mA to any device connected to it. If the current drawn is to exceed the current limit, a

relay should be connected to the PGM as shown in Figure 5 on page 10.
