L-Series Wall-Mount Strobe

Product Overview

The L-Series Wall-Mount Strobe (SRL) is a conventional (dc-operated) visual alarm device intended to alert building occupants of emergency situations.

The SRL provides seven field-configurable brightness settings. These settings are controlled by a switch on the back of the unit.

The mounting plate has a shorting spring that provides wiring continuity before devices are installed. This enables installers to verify the wiring without installing the device. The device need not be installed until late in the construction process, reducing the risk of damage.
