Section 1: MIDS Single Channel Relay (MRLY)
Description
The MIDS MRLY is a single channel, fixed frequency relay that receives and re-transmits RF
signals from a field of MIDS and EMIDS sensors. This field may be any combination of sensors,
such as seismic, magnetic, IR, or break wire. A receiver, transmitter, and control electronics module
are encapsulated in the Lexan plastic housing. The repeated signal will be on the same RF frequency
as the signal that was received from the original detector.
