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):

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

CHQ-DZM - DUAL ZONE MONITOR

This device is an externally powered module designed to allow up to 60
conventional detectors (30 per zone) to be interfaced to Hochiki’s ESP analogue
addressable system. The unit features three End Of Line (EOL) monitoring options
(see page 3 for further details).

Setting EOL Monitoring Option

Select the required EOL monitoring option using the 2-bit DIL switch.
