Figure 7. Two Keypads in a Zone

Niles ZR-KE Keypad Expander

The ZR-KE Keypad Expander enables the use of two Keypads per zone. The RJ-45 terminated CAT-5 cable from the ZR-4 MultiZone Receiver’s Keypad Port is connected to the input of the ZR-KE. The two keypads are then connected to the outputs on the ZR-KE with CAT-5 cable.

Note: The ZR-KE has three outputs, but only two can be used for Keypads with the ZR-4 MultiZone Receiver. One ZR-KE can be used for each

 

zone, including additional Slave zones when a second ZR-4 MultiZone Receiver Kit is used to expand the system to eight zones.
