Signal Module
The Signal Module is used to connect, upon command from the loop controller, supervised
Class B signal or telephone circuits to their respective power inputs. Models are available
with one or two power inputs. These may be either polarized 24 Vdc to operate audible and
visual signal appliances, or 25 and 70V
RMS to operate audio evacuation speakers and
firefighter’s telephones. The actual function of this module is determined by the “personality
code” selected by the installer. A total of three personalities are available.

Control Relay Module
The Control Relay Module provides a Form C dry relay contact to control external appli-
ances such as door closers, fans, dampers etc. This device does not provide supervision of
the state of the relay contact. Instead, the on-board microprocessor ensures that the relay
is in the proper ON/OFF state. Upon command from the loop controller, the relay activates
the normally open or normally-closed contact. This module supports only one personality:
no user configuration is required.

Polarity Reversal Relay Module
The Polarity Reversal Relay Module provides a Form C dry relay contact to power and
activate a series of SIGA-AB4 Audible Sounder Bases. Upon command from the Signature
loop controller, the SIGA-CRR reverses the polarity of its 24 Vdc output, thus activating all
Sounder Bases on the data loop. This module supports only one personality: no user
configuration is required.

Riser Monitor Module
The SIGA-RM1 Riser Monitor Module is an intelligent device that monitors the integrity of 24
Vdc, 25 Vac, and 70 Vac circuits, as well as telephone riser signals. Upon the loss of a signal,
the Riser Monitor Module causes the fire alarm control panel to indicate an alert status.
Personality codes downloaded to the Riser Monitor Module during system configuration
determine its function.
