Installation, Operation & Maintenance

Detector ID Switches

When wiring multiple detectors it is important to identify each detector installed for

the control panel to receive and display accurate data corresponding with the

correct device.

The ID configuration diagram is printed onto detector boards for quick

reference as shown opposite. All detectors are factory set to ID1.

We recommend a plan, map and/or marking the detector enclosures detailing ID and location!

ID Switches must be configured for each detector connected to receive and display accurate data!

120ohm Termination Resistance

Signal communication issues may occur where the bus length is too long, high baud

rates are used or signal reflections are occurring. To avoid this, terminating at each end

of a chain may help the quality of the data signal by turning on the 120-ohm terminal

resistor switch.

If a split chain is used, terminate the last detector in each chain.

If a single chain is used, terminate the first device (Panel) and last device (Detector).

Quick Circuit Test

When the test button on the detector board is pressed and held – the detector will simulate an open circuit to ensure

all configured systems, outputs, alarms, indications and other external devices operate as intended in response to

gas. When the test button is released – the test sequence will terminate and return to normal operation.
