System Output Activation:
- an ALARM contact for the ALARM transmission to the
Main Fire Alarm Building panel will be activated.
- an ALARM signalling circuit will be activated.
- the CAF discharge will occur and the DISCHARGE
contact will be activated for auxiliary function.
Automatic Discharge
The CAF discharge will occur for 10 minutes. At the end of
the soak timer, the CAF discharge will automatically stop.
The Release LED will then start flashing.
Emergency discharge Shut-Off
Because the ICAF System cannot be turned off by the
operation of a single valve as is the case for a standard
sprinkler system, a manual shut-off function is provided. The
CAF discharge can be manually suspended using the
following sequence of operation:
1. Press and hold the function key F3 labelled: "System
Shut-Off" on the keypad of the ARC-1 panel until its
adjacent red lamp is turned On.
2. Close the system main water supply valve inside the
ICAF cabinet. The red lamp labelled "Discharge
suspended" will turn On.
Note
: Mechanical emergency release valve must be in
normal position prior the CAF discharge shut-off.
IMPORTANT
: After a fire, make sure it is completely
extinguished. If necessary, place a fire patrol in the
zone covered by the system. Foam systems that have
been subjected to fire must be returned to service as
soon as possible. The entire system must be inspected
for damage, and repaired or replaced as necessary.
Warning!
DO NOT CLOSE THE WATER SUPPLY TO
MAKE REPAIRS WITHOUT PLACING A FIRE PATROL
IN THE AREA COVERED BY THE SYSTEM. THE
PATROL SHALL REMAIN THERE UNTIL THE SYSTEM
IS BACK IN OPERATION. Advise local authorities of the
necessary work over the fire protection equipment.
Follow emergency procedures required by codes and the
Authority Having Jurisdiction during system maintenance.
Note
: BEFORE CLOSING A VALVE OR ACTIVATING AN
ALARM, ADVISE THE SECURITY GUARD AND THE
CENTRAL SUPERVISORY STATION. THIS IS TO
AVOID DISPATCHING THE FIRE DEPARTMENT IN
CASE OF A FALSE ALARM.
Inspection Log
The function key F1 labelled "Inspection Log" is used in
conjunction with the ARC-1 Remote Interface software for
PC.
