CHQ-LID Transparent Module Lid

(Supplied with four screws and acrylic retaining washers)

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):

The switches should be set using a small-tipped screwdriver or similar.

Refer to the Address Chart (Fig 9) 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

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 with Back Box

Fig 9

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.

Status LEDs

Refer to the table below for Status LED indications:

CHQ-DIM (all variants) Dual Input Module

CHQ-SZM (all variants)

CHQ-DZM (all variants)

Single Zone Monitor

Dual 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 (CHQ-DIM only). Amber LED is continually illuminated when unit detects short-circuit fault.
