The System Sensor P2RL is a wall-mount horn/strobe notification appliance designed for indoor fire alarm signaling applications. It combines an audible horn and xenon strobe to provide both audible and visual occupant notification from a single device. The unit operates on regulated 12 VDC or 24 VDC/FWR notification appliance circuits and connects using a two-wire configuration.

The device includes field-selectable strobe intensity settings and configurable horn tones. A rotary switch on the device allows installers to select among multiple horn patterns and volume levels, including temporal and non-temporal tones. The strobe flash rate is fixed at one flash per second and uses a xenon flash tube and reflector system to meet fire alarm visual signaling requirements.

The P2RL mounts to standard electrical back boxes using a universal mounting plate that allows wiring continuity testing before the device is installed. It is intended for indoor wall applications and integrates with compatible fire alarm control panel NAC outputs or synchronization modules that support System Sensor synchronization protocols.
