IM1 Input module

IM1 input module is designed for alarm receiving from the devices with dry contact output type, which are not connected to the loop, as well as to transmit the alarms to the receiving and control panel. It is designed to operate as a part of the addressable system controlled by the R3500 receiving and control panel.
Power supply from ACL (24 - 36 V)
Number of control lines:  
IМ-1 1
Maximum length of the line between the input module and a dry-contact output device, no more than  100 m
IМ-1 current consumption, at most  0,18 mА
IМ-1 module overall dimensions, at most 51х51х24 mm
Weight, no more than 30 g
Operating temperature range from -25 to +60°С
Average service life, at least 10 years

Input module helps to control failures (break, short circuit) of communication line between the input module and the device under control.

By the alarm loop resistance control, addressable mark transmits corresponding event alert (contacts closing/opening, failure) to receiving and control panel with address specified.

Input module power supply as well as signals transmission to receiving and control panel are realized via addressable communication line. IM1 input module may be installed in DIN rail using special securing bar (not in the scope of supply; may be provided by separate order).

At the input module board, there is a button used as a decapsulation sensor as well as for device addressing at the receiving and controlling panel.

Every input module’s loop may be connected with one or two detectors with dry contact type output. Parallel to each annunciator, bypass resistor shall be connected. Detectors contacts may be either normally closed or normally opened. Initial configuration is required for correct identification of detectors connected. 


During the input module configuration the following parameters should be set:

  • Type of sensor's contact - 1 sensor: NC/NO - 2 sensor: NA/NC/NO

  • Configuration: Fire/Guarding/Process.
