The JA-181M is designed to detect the opening of doors, windows etc. It can also be extended by 1x normally closed / normally open sensor (IN1) and 1x to a roller contact (IN2), connected to its wired input. For example existing (non-Jablotron) fire detectors, flood detectors or a mercury switch.

  • IN1 – If the IN1 terminal is disconnected from GND it sends the same signal to the control panel as if the magnet had been removed from the detector. The internal magnetic sensor can be disabled by the DIP switch if desired.
  • The balanced loop feature can be used when the connection of a detector with a NO output is needed. The resistor is then shorted out by the closing contact and the detector is triggered.
  •  IN2 – The IN2 input terminal receives signals from the ratchet-wheel CT-01. Alarm signals are then only transmitted when the ratchet contact is opened at least three times within 10 seconds. This filters out disconnections caused by accidental ratchet-wheel shifts, which are due to wind blasts. When the IN2 input is opened for more than 1 sec a tamper signal is sent.
