Capabilities
When installed with a Sensiscan 2000, an annunciator can annunciate the status of
initiating and notification circuits, relays, and several system control functions. Each
annunciator LED is automatically assigned to one and only one system point:
Circuits:
IZ-8F, IZ-4F Initiating Device Circuits (alarm and trouble)
IC-4F/ICE-4F Notification Appliance Circuits (trouble)*
CR-4F/CRE-4F Control Relays (trouble)*
TC-2F circuits (trouble)*
TC-4F circuits (trouble)*
* Indication of output circuit activation can be obtained by programming the CPU for
"OUTPUT STATUS."
System
Acknowledge
Controls:
Signal Silence
System Reset
Activate Notification Circuits 1 and 2, the Remote Signalling
Municipal Tie circuit, and the Alarm Relay.
System Trouble Indication
Communication between the CPU and the Annunciator Control System is accomplished
over a two-wire EIA-485 serial interface. This communication circuit is supervised by the
FACP. Loss of communication results in "System Trouble" and "Module Failure"
indications at the FACP CPU.
