Of all the security industry wireless protocols, only the GE wireless protocol enables the use of multiple sensor repeaters in a system.
In a GE system, where RE524X sensor repeaters are used, the signals will only go through one sensor repeater, and will be stopped at the next sensor repeater.
The GE installation can be made in a “star” pattern, with for example, and East Wing sensor repeater and a West Wing sensor repeater. Bucket brigade (daisy chain) type installations will not work.
All other security industry wireless protocols, such as Napco, Honeywell, 2GIG, DSC, are problematic, because the signals can loop from repeater 1 to repeater 2 to repeater 1 to repeater 2… forever.
The evidence of multiple sensor repeaters infinitely looping are that the green LED (I heard something) and the red LED (I am saying something) flicker for periods more than say 5 seconds.
Even if only one sensor repeater is in an installation, it is possible for a neighboring installation’s sensor repeater to join the party and cause problems.
