Product Features：
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. The alarm bus is isolated from the DC24V
power bus and enhances the anti-jamming performance.Can detect the
input signal and DC24V power line break, short circuit fault signal.Its DC24V
power output has a reset power-off function, so that the switching device in
the alarm state can be reliably reset when the controller is reset.
