OVERVIEW
Any zone of the ZR-6 MultiZone Receiver can be expanded to contain up to three keypads. This is ideal for large rooms, bedrooms, and
outdoor applications.
NILES ZR-KE KEYPAD EXPANDER
The optional Niles ZR-KE Keypad Expander (FG01494) enables the use of up to three keypads per zone. An RJ-45 terminated CAT-5 cable
from a ZR-6 MultiZone Receiver keypad port is connected to the input of the ZR-KE. The three keypads are then connected to the outputs
of the ZR-KE using CAT-5 cable. One ZR-KE can be used for each zone, including any Slave zones when multiple ZR-6 MultiZone Receivers
are used to expand the number of system zones.
KEYPAD POWER VALUE (KPV)
When a large number of keypads are used in a system, additional power may be required to power the keypads. An optional power supply
(Niles 12VDC Universal Wall Adaptor FG01035) connects to the ZR-KE to supply this additional power, if necessary. To determine if the
keypads require additional power, calculate the keypad power value (KPV) by adding the point values of all keypads connected to each
chassis.
A single ZR-6 MultiZone Receiver Chassis will supply
power up to a total KPV of 30 points. Exceeding this
KPV will compromise operation of the MultiZone
Receiver and/or keypads.
