System Sensor P4RK-R Wall-Mount Horn Strobe Red 4-Wire Device Only

System Sensor P4RK-R Wall-Mount Horn Strobe Red

Overview

The System Sensor P4RK-R is a 4-wire wall-mounted horn strobe designed for indoor fire alarm and emergency notification systems. Operating at 12VDC, it combines audible (horn) and visual (strobe) signaling in a single compact unit with red lens — standard for commercial, institutional, and multi-tenant environments where dual notification is required by code. The P4RK-R plugs into a universal mounting plate with minimal back-box intrusion, reducing installation labor compared to separate horn and strobe devices.

Compatibility

The P4RK-R is engineered for 4-wire fire alarm system architectures and is electrically compatible with SpectrAlert Advance control panels and legacy SpectrAlert devices. It requires a 12VDC power source regulated at 12 or 24 volt operation (auto-selectable). Verify compatibility with your specific control panel model and wiring configuration before ordering — 4-wire systems differ from conventional (2-wire) architectures in supervision and addressability.

Installation Notes

The P4RK-R mounts using a universal mounting plate fitted with an onboard shorting spring for pre-installation wiring continuity checks — test before inserting the device to catch ground faults before energizing. Horn output is rated 88+ dB at 16 volts in a reverberant test room; actual site SPL will vary with room acoustics and distance. Strobe candela is field-selectable via rotary switch across a range of 15, 15/75, 30, 75, 95, 110, 115, 135, 150, 177, and 185 candela settings — match candela to the room size and occupant density per fire code requirements (NFPA 72 Table 18.3.5.3.1). White and red housings available; confirm red lens fits your notification color scheme and local code mandates. Do not subject to moisture or exterior UV without verifying outdoor-rated variant availability.
