Availability: In Stock

Condition: New
Brand: Edwards, EST
Status: Active
SKU: 43682
Manufacturer Part #: G1M


The Signal Master is a simple-to-use accessory that adds enhanced features to Genesis strobes and horn-strobes as well as Enhanced Integrity strobes. It is a dual-purpose module that provides precision synchronization for connected strobes, and independent control for connected Genesis horns over a single pair of wires.

All Genesis and Enhanced Integrity strobes are self-synchronizing. When installed with the Signal Master, strobe flashes from devices on the same circuit are synchronized to within 10 milliseconds of each other indefinitely. This exceeds the latest UL 1971 requirements in effect as of November 2000, which specify this level of synchronization over only two hours.

When installed with Genesis horn-strobes, the Signal Master permits independent horn control (on, off, and coded signals) over a single pair of wires. Two methods of horn control are available: traditional NAC signal silence; or, normally-closed contact. Both methods may be used to silence horns without turning off strobes on the same circuit. Note: independent horn control is available for horn-strobes only. G1-P Series steady horns are not compatible with this feature.

Two mounting options ensure trouble-free installation of the Signal Master Module. The “snap-on” piggyback model doesn’t require a separate electrical box. It simply snaps to the back of the first signal on the circuit. The remote mount model mounts in a North American 21⁄2 inch (64 mm) deep one-gang box. It may also be mounted to any SIGA-MP mounting plate, or directly to the rails provided inside BPS Remote Booster Power Supply cabinets.
