Setting the Loop Address
‰
‰
‰
The analogue address of the Module is set using the first 7
switches of the 8-bit DIL switch, which in the case of the
Standard CHQ is located through the cut-out section on the
top of the PCB cover. On the DIN version, this switch is
located on the edge of the PCB behind the clear door (see
Fig 3).
The switches are numbered 1 to 8 (left to right) and each
switch should be in the UP position for “ON” and DOWN for
“OFF” and should be set using a small-tipped screwdriver or
similar.
Refer to the Address Chart (Fig 10) on page 4 for a quick
reference on addresses.

CHQ-DIM DUAL INPUT MONITOR
This device is a loop-powered module designed to interface to a variety of inputs, such as, door contacts, sprinkler flow/door
switches and plant equipment fault contacts, this module is particularly suited to applications where a fast response is required
to the input change.
Setting Contact Monitoring
Both volt free input contacts can be configured to
be either N/O or N/C, by setting the 2-bit DIL switch
(see Fig 4).
DIL Switch Bit 1 = INPUT 1
DIL Switch Bit 2 = INPUT 2
ON = Normally Closed (N/C)
OFF = Normally Open (N/O)

2-3-0-778/ISS1/APR07
Hochiki Europe (UK) Ltd
CHQ-SZM SINGLE ZONE MONITOR is a loop-powered module that provides a single fully monitored input for the
connection of up to six Hochiki conventional smoke or heat detectors, OR one Hochiki beam detector, or any number of
conventional call points, the unit also contains an output for remote fire indication.
Note: The end of line device (EOL) is supplied
with the unit – do NOT discard in error! The EOL
device MUST be fitted at the last detector on the
zone, note the polarity.

Installation – "Smart-Fix" Version
Set analogue address before installation (see page 1). The
fixing surface should be dry and stable.
‰ Hold the back plate up against the fixing surface and
mark the position of the four corner fixing holes.
‰ Determine which cut-out sections along the top and
bottom edges of the module require removing to
accommodate the cables being used.
‰ Remove cut-outs by scoring with a sharp knife before
breaking off with pliers or snips.
‰ Mount the back plate using appropriate fixings (not
supplied) for the fixing surface.
‰ Terminate and connect field wiring as per the wiring
diagrams on pages 2 & 3 (and the terminal block
indications on the product label).
The transparent lid (CHQ-LID) is supplied with four screws
and eight retaining washers.
‰ Push the screws through one of the retaining washers
and then through the holes in the lid from front to back,
pushing another retaining washer onto the end inside
the lid.
‰ Screw the lid onto the back plate; do not over tighten
the screws as this could damage the unit.
Note, a white plastic version of the lid is available (sold
separately – CHQ-LID(WHT)).
Installation – "Smart-Fix" with Back Box
For those installations requiring glanded cables, a module
back box (CHQ-BACKBOX) is available (sold separately).
Fig 10
This features ten knock-out cable entries (glands are not supplied). Ensure glands used conform to IP67, if such ingress
protection is required. The CHQ-BACKBOX is mounted on the fixing surface; the CHQ Module is then fitted to the top of
the back box. Finally the CHQ-LID is added creating a sealed enclosure. For further details refer to the CHQ-BACKBOX
Instructions (2-3-0-800).
Installation – DIN Version
Set analogue address before installation (see page 1) and write loop address in space provided on door label.
‰ Clip onto an appropriate DIN Rail, which should be mounted within an approved enclosure with the loop connections
at the bottom of the unit.
‰ Terminate and connect field wiring as per the wiring diagrams on pages 2 & 3 (and the terminal block indications on
the product label).
‰ To comply with EMC regulations, these products must be fitted in a protective enclosure.
‰ Suitable anti-static precautions must be taken when handling these products.
Status LEDs
Refer to the table below for Status LED indications:
CHQ-DIM (all variants)
Dual Input Module
CHQ-SZM (all variants)
Single Zone Monitor
Green LED flashes each time the unit is polled by the
fire alarm control panel and is continuously illuminated
when either input is active.
Amber LED is continually illuminated when unit
detects short-circuit fault.
