e) 814CH Analogue CO (Carbon monoxide) Detector + Heat Detector
This unit uses a special sensor to detect carbon monoxide, and in addition incorporates a
temperature sensor. The heat function may be programmed in the same way as for the
814H detector.
f)
Mini Input Module MIM800
This unit has a single input for monitoring clean contacts (e.g. MCPs, flow switches
conventional detectors with hard contact outputs, relay contacts, switches). As well as
monitoring the state of the contacts the MIM800 can supervise the wiring for open circuit
fault and (optionally) short circuit fault.
g)
Mini Input Module MIM801
This unit has a single input for monitoring clean contacts (e.g. MCPs, flow switches,
conventional detectors with hard contact outputs, relay contacts, switches). As well as
monitoring the state of the contacts the MIM801 can supervise the wiring for short circuit
fault and (optionally) open circuit fault. The MIM801 is very similar to the MIM800, however it
is optimised for normally closed applications and can generate an interrupt on an open
circuit. (Interrupt is only used when a fast response is required.) (The MIM800 and CIM800
can also generate interrupts, but only in response to closing contacts.)
h)
Contact Input Module CIM800
This unit has two separate inputs for monitoring switch or relay contacts (e.g. MCPs, flow
switches, conventional detectors with hard contact outputs, relay contacts, switches). As well
as monitoring the state of the contacts the CIM800 can supervise the wiring for open circuit
fault and (optionally) short circuit fault. Although there are two separate inputs, both belong
to the same point. Either input in alarm will put the point into alarm, and either input in fault
will put the point into fault. Unused inputs must be terminated with a 200
Ω resistor.
i)
Detector Input Module DIM800
This unit has two separate inputs for monitoring conventional detectors. As well as
monitoring the state of the detectors they can supervise the wiring for open circuit faults.
Although there are two separate inputs, both belong to the same point. Either input in alarm
will put the point into alarm, and either input in fault will put the point into fault. An external
power supply is required. The voltage requirements for some conventional detector types
are very specific. (Refer to section 3.20).
j)
Australian Call Point Module CP820
This unit consists of a MIM800 complete with a call point switch and break-glass housing.
k)
New Zealand Call Point Module FP0838, FP0839
This unit consists of a MIM801 complete with a call point switch and break-glass housing.
FP0838 is flush mounting while FP0839 is surface mounting.
l)
Relay Interface Module RIM800
This unit has voltage free changeover relay contacts rated at 2A 30Vdc for external loads.
No supervision of load wiring is provided. However the relay position is supervised and a
“relay checkback fail” fault will be generated if it does not operate.
