2 Description
The D129 Dual Class A Initiating Circuit module is a fire system interface to the control panels listed in the table below for fire alarm and waterflow alarm applications. The module has two Class A (Style D) circuits, each with a screwdriver adjustable Alarm Retard and Alarm Reset Delay. Use the Alarm Reset Delay in waterflow applications. You can mount up to four modules inside the control panel enclosure.
The Class A (Style D) circuit is four wire data expansion loop with a feed and return for both the positive and negative sides of the loops. Unlike the two wire loops supervised by an end of line (EOL) resistor, the Class A circuits can detect an alarm condition with a single open or ground fault in the circuit.
The following table lists control panels compatible with the D129:
