SR250 Wireless Siren w/Built-In Strobe Light
Introduction
The SR250 is a weatherproof, stand-alone, fully supervised outdoor
wireless siren with built-in strobe light and wireless transceiver. The SR250
uses 2-way wireless communication, which provides continuous
supervision between the panel and siren with fast response to alarm
signals within four seconds. With its tough weatherproof construction, the
SR250 operates reliably from -30 ºC to 50 ºC (-22 ºF to 122 ºF) when using
alkaline batteries or power supply.
With normal use, the SR250 will function up to 3 years without the need to
replace the batteries (battery life can be extended by using an optional AC
or DC power supply). This guide describes how to install and configure the
SR250 wireless siren.
