The Models PSD-7157 and PSD-7157D Photoelectric Smoke Detectors respond to a broad spectrum of both flaming and smoldering fire conditions. The Detectors have advanced solid-state, low-voltage, surface-mount circuitry and are designed for 2-Wire and 4-Wire installation using the appropriate Detector base. The characteristic 360-degree detector design permits smoke entry from any direction. A unique sensing chamber design permits the operation of the Models PSD-7157 and PSD-7157D in open areas with air velocities from 0 to 300 fpm and 0 to 4000 fpm respectively. The Model PSD-7157D is also suitable for duct housing applications in air velocities from 500 to 4000 fpm. The Detectors are designed for open area/duct housing applications per UL268/UL268A and may be installed in systems intended for Releasing Device Service through use of compatible Fire Alarm Control Panels.
