P2RHK-P Sounder Strobe
Sounder + Strobe Outdoor, 12/24 VDC

The Outdoor Sounder + Strobe (P2RHK-P) is a conventional (dc-operated) alarm device. This is suitable for applications requiring a very bright visual alarm, over and above the performance of standard AS ISO 7240.23 listed devices.
UL listed for wall and ceiling mount applications in wet environments, the P2RHK-P provides seven configurable brightness levels. The P2RHK-P also provides an audible alarm with three volume settings and a choice of temporal (T3) or continuous alarm tone. Rear-mounted switches allow the brightness, tone, and volume to be configured in the field.
This alarm device is supplied with a plug-in mounting plate that allows the wiring to be installed and tested without fitting the alarm device. A shorting spring in the mounting base provides electrical continuity when the device is not plugged in.
A captive mounting screw secures the installed device to the mounting base. The P2RHK-P is supplied complete with weatherproof plastic back boxes that accommodate “line in + line out” wiring. The back boxes feature removable side flanges, ¾-inch threaded top and bottom conduit entries, and 19 mm knock-outs at the back.
A kit containing a red strobe lens and a pair of “FIRE” decals (white text on red background) is available for these alarm devices.
