Infrared Receiver Units (IRUs) are installed in the ceiling no more than 20m apart and are activated by a Personal Infrared Transmitter (PIT) without having to point, from no more than 10m away.

Infrared Receiver Units (IRUs)

Once a staff member activates their Personal Infrared Transmitter (PIT), the IRU is triggered and transmits its 'address' to designated LCD Display Units and other communication devices notifying response staff of the location and type of call.

IRUs include all-over infrared windows as well as supersensitive circuitry to ensure the unit is triggered instantly by the coded infrared transmitters. They are programmed, using a hand-held programmer, either with their own unique address or can be set up to share an address with another unit if required. IRUs come in either black or white.


  • All-over infrared window

  • Programmed in situ with its own unique address (can be shared with other units to give greater coverage in the same area)

  • External Receiver Unit available for outdoor coverage – designed with even more sensitive infrared reception for greater coverage of outside areas (housed in waterproof case)
