Installation – "Smart-Fix" Version
 Set analogue address before installation (see page 2).
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.

Installation – "Smart-Fix" with Back Box
For those installations requiring glanded cables, a module back box (CHQ-BACKBOX) is available (sold separately).
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

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).
