Description
The Honeywell P2RLED Sensor 3 Horn/Strobe P2Rl is used to provide both audible and visual alerts in HVAC systems. Operating on 24 VDC, it combines a horn and LED strobe in a single wall-mounted unit to signal evacuation or alarm conditions. Installed as part of a fire alarm circuit in commercial buildings and other occupied spaces, it works within the system’s notification appliance circuit (NAC) to alert occupants during conditions. It supports, synchronized operation with other alarms, helping ensure consistent and visible warning signals throughout the building.
