System Sensor P2GRLED — L-Series LED Compact Horn-Strobe, Wall-Mount
The System Sensor P2GRLED is a wall-mounted LED horn-strobe notification appliance from the System Sensor L-Series platform. Designed for indoor fire alarm systems, this compact 2-wire device combines audible and visual signaling into a single low-current unit with modern aesthetics and flexible installation features. It’s marked “FIRE” and comes in red to meet code-compliant life-safety requirements.
Key Features & Benefits
-
LED Technology — Uses efficient LEDs instead of traditional xenon tubes, significantly reducing current draw and allowing more devices per Notification Appliance Circuit (NAC).
-
2-Wire Operation — Simple wiring with both horn and strobe on the same circuit makes installation easier and cost-effective.
-
Field-Selectable Candela Settings — Adjustable strobe output (e.g., 15, 30, 75, 95, 110, 135, 185 candela) via rotary switches to meet different coverage requirements without changing devices.
-
Rotary Switches — Allows selection of horn tone pattern and volume levels in the field for application flexibility.
-
Universal Mounting Plate — Plug-in mounting plate with onboard shorting spring lets installers pre-wire and test continuity before final device installation, reducing ground faults and installation time.
-
DVM Diagnostic Points — Some units include Digital Voltage Meter (DVM) test points for quick verification of notification circuit voltage (where supported).
-
Tamper-Resistant Construction — Robust design to deter unauthorized removal or adjustment.
-
Compatibility — Electrically compatible with legacy SpectrAlert, SpectrAlert Advance, and L-Series devices; also synchronizes when paired with approved panels or sync modules.
