• Low power consumption. The T+, T-alarm bus and the DC24V power bus are non-polar designs and can be regarded as the same fire detector connecting to the alarm buswhich is convenient for construction and flexible in use.
• It can be used as the linkage control execution component of the controller and the controlled device, and can also detect the disconnection and short-circuit fault signals of the playback device (speaker) and the connection line.
• The relay outputs two pairs of normally open and normally closed transition contacts (AC125V/1A), which can switch background music signals and fire broadcast signals.

Wiring instructions:
T+, T-: Alarm Bus (with polarity)
24V+, 24V-: 24VDC power supply (with polarity)
PY1, PY2: Ordinary broadcast signals
