The characteristic 360-degree detector design permits smoke entry from any direction. A unique sensing CONTROL UNITS chamber design permits the operation of the Models The Models PSD-7157 and PSD-7157D Detectors are PSD-7157 and PSD-7157D in open areas with air designed for operation with control units and releasing velocities from 0 to 300 fpm and 0 to 4000 fpm devices having specific voltage and current respectively. The Model PSD-7157D is also suitable for characteristics that are compatible with the detector duct housing applications in air velocities from 500 to circuitry. The Detectors are compatible with the Fenwal 4000 fpm. The Detectors are designed for open area/ 732 control unit. The Fenwal 732 has three detection duct housing applications per UL268/UL268A and may circuits which can support up to 26 detectors per circuit. be installed in systems intended for Releasing Device Service through use of compatible Fire Alarm Control Panels.
