  (See specification sheet for detailed performance data.)

520 Hz tone:

• Complies with NFPA 72 requirements for sleeping areas.

• Proven effectiveness in waking sleeping occupants.

Operating modes:

• SmartSync two-wire control: Supports independent horn and strobe operation, allowing horn silencing while the strobe continues flashing. Provides signal patterns such as Temporal, March Time, or Continuous. Strobe flashes in sync at 1 Hz.

• Free-run mode: Horn operates independently, not synchronized.

Selectable sound output:

• High or Low volume levels, adjustable to suit installation environments.

Practical design:

• Impact-resistant, flame-retardant housing.

• Removable cover for easy on-site color/lettering change without interrupting circuit connections.

• Separate mounting base allows pre-wiring before device installation. Compatible with single-gang, double-gang, or 4-inch square (102 mm) boxes, both surface and flush mounted.

• Terminal blocks support in/out wiring with AWG 18–12 gauge, allowing loop-through connections.

• External electrical test point for quick checks without opening the cover.
