Overview

What it is and who it is for

The System Sensor P2WLED is a white, indoor, wall mount two-wire horn strobe from the L-Series with LED line. It uses LED lighting with lower current draw than xenon strobes and is electrically compatible with legacy SpectrAlert, SpectrAlert Advance and L-Series devices on the same circuit.

Rotary switches set candela (15 to 185 cd), tone and volume in the field, and the strobe flashes once per second. It runs on regulated 24 VDC (16 to 33 V); horn strobe current ranges from 35 mA at 15 cd up to 190 mA at 185 cd on Temporal 3 high. Sound output is 87 dBA on high and 79 dBA on low for the Temporal 3 and Non-Temporal patterns. Terminals accept 12 to 18 AWG wire.

The universal plug-in mounting plate has a shorting spring to check wiring continuity before the device is installed, and DVM test points on the face allow voltage checks. For surface mounting it uses the SBBRL or SBBWL surface back box, and the TR-2 or TR-2W universal wall trim ring is available. Synchronization uses UL approved power supplies with the System Sensor Sync protocol or an MDL3 sync module.

  • Best for: indoor wall locations on 24 VDC notification appliance circuits that need audible and visible fire alarm signaling.
  • System fit: System Sensor Sync protocol power supplies or MDL3 sync module; mixes with SpectrAlert, SpectrAlert Advance and L-Series devices.
  • Important to know: indoor use only; installation and setup must be done by a qualified fire alarm technician per local code.
