Gentex GCS24CR Fire Evacuation, 24VDC Ceiling Mount Selectable Candela Strobe - Red Faceplate

you asked for strobes here's your damn strobes yep i just purchased this lot of edward 792's the full model number on these is 792-78-006 and this series of notification appliances is somewhat rare it was produced for a few years in the 1990s before being replaced by the much more widespread integrity series which is still in production 20 years later you've probably noticed this grill and wondered is this a horn strobe or a speaker strobe these are actually horn strobes despite the grille pattern though speaker strobe versions do exist now these are four wire horn strobes but as you can see here some of them came with jumper wires to allow for two-wire operation the horn on the 792 is an electronic horn it's one of those older analog types basically a piezo speaker attached to a projector horn similar to the system sensor mass except that these are single tone and produce a steady low
