Connection Details
Fig. 1
2-1-0-024/ISS9/AUG03
The module should be connected to the loop as shown in Fig.1, the module does not support any line continuity
options, therefore, if manual Call Points are to be interfaced then these should be connected first.
Setting the Loop Address
q The address is set using the first 7 switches of the 8-bit DIL switch. The switch should be in the up position for ON
and down for OFF.
q Set the switches as defined below in Fig 2 for the required address.
Installation
For CHQ-MZ (Enclosure & Module)
q Drill the cable entry holes in the enclosure as
required before fitting the CHQ-MZ/OEM. Ensure
glands conform to IP67, if such ingress protection
is required.
q Mount enclosure as required, using the holes in
the 4 corners which are located through the cover
fixing point.
q Mount the CHQ-MZ/OEM inside the enclosure with
the screws supplied.
q Fix the label to the enclosure and note the unit's
address.
For the CHQ-MZ/DIN
q Clip onto an appropriate DIN Rail, which should be
mounted within an approved enclosure with the
loop connections at the bottom of the unit.
q Write loop address in space provided on door
label.
For both
q Ensure the conventional zone is terminated with
the TE-RH-E (supplied), this must be connected to
the last device on the zone.
q Set the ESP loop address using the 8-bit DIL
switch - see opposite.
q To comply with EMC regulations, these products
must be fitted in a protective enclosure.
q Suitable anti-static precautions must be taken
when handling these products.
Status LED
q A red LED flashes each time the unit is polled by the fire alarm control panel, and continuously illuminated when the
input is active.
