Zone Monitor units
CZMU352
CZMU352 is designed to enable a zone of compatible conven-
tional detectors and callpoints to be connected into the CF2000
loop, it is compatible with up to 20 Menvier conventional detec-
tors connected via CAB300 bases.
Please refer to local standards e.g.BS5839 Pt1:2002 for details
of the maximum allowable area to be covered by a single spur /
zone. CZMU352 fixes to a standard, deep, double gang back box
and can be either surface or semi recess mounted. When semi
recessed only the front section protrudes giving a maximum
29mm depth.
CZMU352-IS
Similar to the above but the detection zone has been programmed
to accept a Zener barrier and a zone of intrinsically safe detectors.
End of line for this zone now becomes 6K8 and the diode in the
detector base must be removed.
Shop Unit Interface
MSU840 accepts a zone of conventional detectors plus an unlim-
ited number of callpoints which can be connected to the same
input as the detectors or a separate callpoint input if required. It
also has a 24V 1A rated relay output, and a facility to connect a
power supply, which can then be monitored for fault.
In addition it has the facility to connect two circuits of conven-
tional polarised sounders, which are monitored by means of an
end of line resistor and powered in alarm conditions from the
external power supply.
The sounder circuits can be programmed to operate in pulsed,
continuous or time delayed mode.
Please refer to local standards e.g. BS5839 Pt1:2002 for details of
the maximum allowable area to be covered by a single spur / zone.
