Supervised Siren Module must be wired to the Model 4720. To warn of a
fire, the module provides a UL temporal-three siren that uses three distinctive, repeating
short beeps. The module converts the communicator’s non-supervised, pulsed fire
cadence to a supervised, temporal-three fire cadence. This module also provides a
distinctive supervised burglary (police) siren. See Figure 2a for details on wiring the
module to the Model 4720. For additional information, see the Regency Supervised Siren
Module Installation Instructions (P/N 466-1584).
