SIGA-CRR Polarity Reversal Relay Module
Installation Sheet
Description
The SIGA-CRR Polarity Reversal Relay Module is an
addressable device that is used to power and activate the
audible sounder in Signature audible detector bases.
The module can support a 2 A load of bases. Upon command
from the loop controller, the SIGA-CRR module relay transfers,
reversing the polarity of its 24 VDC output.
The module requires one address on the signaling line circuit
(SLC). Addresses are assigned electronically. There are no
address switches.
Diagnostic LEDs provide visible indication of the state of the
module through the cover plate:
•
Normal: Green LED flashes
•
Alarm/active: Red LED flashes
Personality code
The module requires the loop controller to download the
personality code that determines how the module operates.
Use the personality codes described below to configure the
SIGA-CRR. See Table 1 for listing information.
Personality code 8:
Signal - dry contact output. Configures
the module as a dry relay contact to control external
appliances (door closers, fans, dampers) or equipment
shutdown.
