Model 2001TRB
This option uses a transformer/rectifier for primary system power with battery
back-up and allows the siren to operate from a 208, 220 or 240 VAC power source
without the use of the batteries. During a power failure, an automatic switch to
battery operation occurs to maintain the siren’s normal operation. Specify the AC line
voltage when ordering.
The 2001TRB has a 115 VAC secondary tap to provide power to the siren control
cabinet.
2001TRB Mounting Location
Keep wire lengths to a minimum. Mount the transformer assembly as close as
possible to the Control Unit/Battery Box.
