Hochiki Europe (UK) Limited 2-3-0-1366/ISS3/DEC11
Installation – "Smart-Fix" Version
Set analogue address before installation (see previous page). 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 diagram on
pages 2 (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 with Back Box
For installations requiring glanded cables, a module back box (CHQ-BACKBOX) is available (sold separately). This is
mounted on the fixing surface; the CHQ Module is then fitted to the top of the back box and the CHQ-LID is added
creating a sealed enclosure. For further details refer to the CHQ-BACKBOX Instructions (2-3-0-800). For installations
utilising heavy-duty cabling (for example, 1.5mm
2
solid conductor) the use of the SMB-1 Box with the SMB-ADAPTOR
plate and CHQ-ADAPTOR is recommended. For further details refer to the SMB-ADAPTOR Instructions (2-3-0-1502).
Ensure any glands used (not supplied) conform to IP67, if such ingress protection is required.
Installation – DIN Version
Set loop address before installation (see page 2) and write loop address in space provided on door label.
 DIN modules should be mounted in a suitable enclosure in conjunction with an NS 35 mounting rail with the loop connections
at the bottom of the unit. Hochiki recommends the SMB-2 and SMB-3 Boxes designed specifically for this purpose.
 Terminate and connect field wiring as per the wiring diagram on page 2 (and the terminal block indications on the product
label).
 Suitable anti-static precautions must be taken when handling these products.
