2 Wire Outdoor Strobe, 12/24 VDC


The Outdoor Strobe (SRHKRLFIRE) is a conventional (dc-operated) alarm device with a red lens. It is suitable for applications requiring a very bright red visual alarm, over and above the performance of AS ISO 7240.23 listed devices.

UL listed for wall and ceiling mount applications in wet environments, the SRHKRLFIRE provides eleven configurable brightness levels. Rear-mounted switches allow the brightness 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 SRHKRLFIRE is supplied complete with a weatherproof plastic back box that accommodates “line in + line out” wiring. The back box features removable side flanges, ¾-inch threaded top and bottom conduit entries, and 19 mm knock-outs at the back.
