RF Integrity ‘Heartbeat’ Transmitter

£115.00 excl VAT

  • The QT421 Monitored RF Integrity Transmitter is intended for use with Quantec’s QT422RX Radio Receivers.
  • Helps ensure RF integrity and site coverage at all times by sending a periodic RF test transmission to Receivers with the same RF group address.
  • Flags a fault at the Quantec Controller if a transmission is not received.
  • Typically located at strategic points on the installation – we recommend at least one RF Integrity Transmitter is used per Radio Receiver.
  • Mountable on a 25mm UK single gang back box.
  • Takes its power from the Quantec network but is not an addressable device as it is monitored by the radio receiver(s) it is set to work with.
