If the line continuity option has NOT been selected, the power supply must be connected to the receiver first.

The CHQ-Z Dual Zone Monitor can also be used to interface the SPC-ET to the analogue loop, but this device requires
an additional auxiliary 24Vd.c. power supply.
There is a set of jumpers on the rear of the Receiver interface kit PCB, these relate to three types of zone fault monitoring
that can be selected. These are, schottky diode, zener diode and open circuit, the link settings can be found listed below:
Schottky Diode - LK1, LK3, LK4 and LK6 are all made
Zener Diode - LK2 and LK5 are made
No line continuity (open circuit) - LK1, LK4 and LK6 are all made (this setting is recommended when used with
either the CHQ-MZ, CHQ-Z, CHQ-SZM or CHQ-DZM modules
The Receiver interface kit can now be screwed to the Dual Gang back box.
The same procedure should be carried out at the Emitter end by terminating the power cables, the power for the Emitter
can be obtained directly from the conventional zone, an Aux. 24Vd.c supply or directly from an ESP Loop (see Fig.1).
The cables should be passed through the top of the back box and then connected into the four way connector block. The
four-way connector block should then be pushed onto the four-pin socket located on the rear of the Interface Kit PCB.
The Emitter interface kit should then be screwed to the Dual Gang back box.
The Emitter unit can now be fixed to the Interface kit by terminating the two-way ribbon cable (brown & red) into the push
friction connectors on the front of the unit (these are not polarity conscious). This is achieved by opening the Emitter
cover by pressing the sides of the cover at the top and then lifting and pulling gently (please refer to Fig.2.). The stripped
ends of the cable should then be passed through the back of the Emitter, and located into the push friction connectors
(E1 and E2) on the front of the unit by gently pushing the white slotted sections of the connector with a small screwdriver.
The cables can then be pushed into the holes and the white slotted sections of the connector can be released, this should
then grip the cable securely.
The two-part black
connector can then be
pushed onto the two pins on
the front of the PCB.
The Emitter can then be
mounted onto the Interface
kit by aligning the four
mounting slots on the rear of
the Emitter with the four
mounting hooks on the
mounting bracket and then
sliding the Emitter down
gently.
The 10-way ribbon cable
can now be fixed to the
Receiver. This is achieved
by opening the Receiver
cover (refer to Fig.2) and
passing the cable through
the back of the unit.
Starting with the black cable
in NC, terminate each cable
(from right to left) in order
finishing with the white cable
in the FC connector (Please
refer to Fig.3.).
The 10-way black connector
can then be pushed onto the
connector on the front of the
PCB.
