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)).
Fig 9 Installation with Back Box
For CHQ-DIM or CHQ-SZM 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
CHQ-DZM 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 analogue address before installation (see page 1) 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 diagrams on pages 2 & 3 (and the terminal block indications on the product
label).
 Suitable anti-static precautions must be taken when handling these products.
