Model FEC
– 6:
An Engine Room Relay Controller can be fitted (model FEC-6) and any zone can be
associated to that engine relay box.
If there is a fire in a zone associated to the engine relay box - in auto mode it will
automatically shut down fans, fuel pumps and/or any device attached to that relay box, in
manual mode it will ask you to press the Ent key to start this process.
When a fire is detected in a zone that has been associated with the engine controller (FEC-6)
and the FR-8000 (MDU) is in
Manual Mode
the display will show:
When the Ent key is pressed the following will happen on the FEC-6:
Relay 1, 2, 3 and 4 will activate.
Relay 2 and 3 can be delayed by adjusting the trim pot (next to the address select rotary
switch) marked Rel 2 and Rel 3. Rel 2 adjusts the time for Relay 2 and Rel 3 adjusts the time
for Relay 3. Turn Anti-clockwise to increase time.
Relay 2 Min time = 0 seconds, max time = 1 minute.
Relay 3 Min time = 0 seconds, max time = 1.5 minute
Relay 4 has a delay associated to it called the Eng Stop Time, which is setup in the Controller
Menu on the FC-8000 (MDU). When the programmed time has elapsed Relay 4 will activate.
Example: If the solenoid on the extinguisher bottles is connected Relay 4 and the stop time is
set to 30 seconds, this would give a 30 second window for the fans and engine (connected to
Relay 1 & 2) to stop before the extinguisher is set off.
Relay 5 & 6 are associated with the manual extinguisher trigger cupboard door.
If the extinguisher trigger cupboard door is opened Relay 5 & 6 will activate. Relay 6 will stay
activated until the door is closed, Relay 5 will deactivate when the Mute key is pressed on the
FR-8000 (MDU). Example: Relay 6 connected to the evacuate engine room light and Relay 5
connected to a buzzer.
When a fire is detected in a zone that has been associated with the engine controller (FEC-6)
and the FR-8000 (MDU) is in
Auto Mode
the above will happen automatically.
Model FEC
– 1:
The FEC-1 is a single Relay unit, which could be used instead of the FEC-6 if only 1 Relay is
required. Example: To turn on the evacuate engine room light.
Model FR-100:
The FR-100 has two relays Relay 1 & Relay 2. Both Relay 1 and Relay 2 will only activate on
Fire detection. Relay 1 will de-activate when the alarm is muted while Relay 2 will stay
activated while Fire is displayed on the MDU.
