The FR-4000 Alarm Monitor has been developed to allow monitoring of up to 4 zones.
It is a network-based system consisting of a Master Display Unit (FR-4000), a Sensor
Input Unit (FR-100), Smoke Sensors and an optional Engine Room Relay Controller
(FEC-6).
A 4-wire network cable interconnects all devices. The Master Display Unit (MDU) controls
communication with the Input / Output Unit (IOU). System components may be located
anywhere on the network cable and the cable may be up to 1000 meters in length.
Each area which are referred to as zones, can have multiple sensors. 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 (see page 14 for relay details). In manual mode it will ask you to press the enter
key to start this process.
An extinguisher trigger cupboard door or doors may be connected to a Sensor Input
Unit (FR-100).
This input is fully monitored and if the extinguisher trigger cupboard door is opened
then the alarm buzzer will sound, the Master Display Unit will display ‘Open’ and
relays 5 & 6 will close on the Engine Room Relay Controller (FEC-6) or relay 1 on
(FEC-001). See page 14 for relay details.
The extinguisher bottle pressure switch may be connected to the Engine Room Relay
Controller (FEC-6) see page 10 for details.
This input is monitored and if the extinguisher bottle is empty the Master Display will
display “Empty” if full it will display “OK”
Input 1, 2, 3 and 4 are all internally connected in the FEC-6 so multiple bottles may
be connected. If multiple bottles are connected and one is empty the display will
show “Empty” therefore all bottles will need to be inspected to locate the empty one.
Optional:
Pyro-5 Pyrogen interface module
This module will monitor up to 5 Pyrogen extinguisher bottles, also has bottle release
input.
