TrueAlert ES Wall Mount Multi-Candela Strobes 59VO

The TrueAlert ES Series 59VO is a visible-only LED strobe notification appliance, designed for wall-mount applications. Each device is individually addressable and operates on an IDNAC SLC (Signaling Line Circuit), receiving power, supervision, and control signals over a two-wire connection directly from the fire alarm control panel. Its efficient LED design reduces system load and provides reliable operation even during battery backup conditions.
