Zone Monitoring Units
MIU 871
This is a true Zone monitor with 2 inputs, one for a zone of conventional call points the second for a
zone of conventional detectors (max 20). End of line for the call point zone is 6K8, end of line for the
detection zone is the EOLM 1 (the JSB FXN 520 series can only be used on this zone).
MIU 871/IS
Similar to the above but the detection zone has been programmed to accept a Zener barrier and zone
of intrinsically safe detectors. End of line for this zone now becomes 6K8 and the diode in the detector
base must be removed.
MIU 871CUK
This device has been programmed as a Technical input similar in effect to the Non fire input. This
device can be used in conjunction with a Fan controller, and can be used to provide confirmation of
operation (feedback) from an extract fan or smoke vent.
MSU 840
Another zone monitor similar to the MIU 871, this unit also has a fire relay rated at 30v 1A and 2
conventional sounder circuits fully monitored. The power supply, which is also monitored, is the FX1A
and must be fitted even if the sounders are not used.
MSU 840C
This device provides the output to control an extract fan or smoke vent in conjunction with a Fan
control unit.
Fan Controller FC6
The FC6 Fan Controller is designed to satisfy the requirements of Australian standard AS1668 & can
be connected to a Cooper analogue addressable fire alarm control panel by means of the comms
Loop utilizing only one address.
There are 6 channels per Fan Controller capable of controlling & indicating 6 individual Fans.
Each channel is programmed to an output device and feedback input device in the loop (for example,
MSU 840-C, MIU871cUK modules) to control & monitor the status of the Fan.
A new module has been created which provides 2 addresses the first to control the feedback the
second to provide output and reset controls for the fan
In Automatic mode the Fan is controlled by the DF6000 in the normal way through the site installer
program. Feedback must be detected from the Technical input within 25 secs or a fault will appear on
the FC6
In manual mode the Fan can be started and stopped using the Start/Stop buttons on the FC6, again
once the start button has been operated then feedback must be received within 25 secs.
