LA1 Power Supply with Alarm Outputs

The LA1 AC Power supply operates the LA1 level alarm on 120 or 240 volts AC. The batteries act as a backup power supply in case of power failure. It also has 4 internal solid state relays to switch external loads such as an annunciator alarm or solenoid valves. The outputs can be set to trigger on individual float switches, or on any alarm trigger.
