Device Addressing
Device addressing is handled by the REACH Wireless Loop-
Interface device (RW1700-030APO).
Devices are soft-addressed automatically when pairing with
the Loop Interface and can be changed manually. Hard-
addressing using Apollo XPERT cards are not supported.
Communication
REACH Wireless Devices use ‘radio-frequency’ wireless
communication to connect to the Loop-Interface.
The Loop-Interface (RW1700-030APO) translates the wireless
communication into wired Apollo protocol communication,
with each device addressable individually by the fire panel.
See datasheets for the Loop-Interface for more information.
Maintenance and Service
Maintenance must be performed in accordance with all
applicable standards. Clean the detector externally using a
soft damp cloth. For full cleaning and recalibration detectors
should be returned to Apollo Fire Detectors.
Batteries
REACH Wireless devices are supplied with two CR123
batteries, battery A and B. The device switches periodically
between the two batteries on a controlled sequence. For
correct operation of the device, both batteries are required
with adequate capacity reserves.
When battery A reaches a low power threshold, it will trigger
a fault. This fault requires both batteries to be replaced in
every instance as both batteries should be discharging
equally.
When one (or both) batteries lack power, the Loop-Interface
receives a low battery message and will signal this event on
its in-built display, as well as relay the low battery message to
the fire control panel. The battery fault will also be signalled
by the device itself through its LED indicators if programmed
(see table 1).
