FR-100 Input / Output Unit (IOU)
The FR-100 is a controller, which provides 4 Zone Inputs for Smoke Sensors and 1
Output Relay.
•
Each Input requires 4K7 end of line resistor for supervised line
•
Minimum fault sense current = 8mA
•
Output Relay’s
o
10 A resistive @ 24VDC
o
Relay 1 & Relay 2 close on Fire detection
o
Relay 1 opens when alarm is muted
o
Relay 2 opens when all zones are OK
