IM502 Input Module Introduction
The IM502 input module is an input module with address code designed for connecting the switching quantity (conventional quantity) bus device.
The IM502 input module can convert and transmit the normal monitoring, alarm and fault signals of smoke sensing, temperature sensing fire detector and other devices to the fire alarm controller. The module has the function of line break and short circuit fault detection.
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.
