SATCO Lighting 67-113 Red (Clear) Edge Lit LED Exit Sign, 90min Ni-Cad backup, 120/277V, Single Face, Top/Back/End Mount

All three. The 67-113 edge lit LED exit sign ships for top, back, and end mount, so you can hang it from the ceiling, surface it flat to the wall above the opening, or run it off the end of a wall as a flag mount for corridor visibility. No separate canopy kit or different part number for each orientation.

Either one. The 67-113 is dual voltage, 120/277V, so the same sign works on a 120V lighting circuit in a small commercial space or on a 277V circuit in a larger building. That matters if you are standardizing exit signs across a facility where the voltage differs floor to floor.

Yes, it has an integral nickel-cadmium battery rated for 90 minutes of emergency operation. Ninety minutes is the standard duration inspectors look for on egress illumination, and the Ni-Cad chemistry is what most commercial exit signs use because it tolerates the constant float charge.

Single face. The legend reads from one side only, which is what you want above a door where traffic approaches from a single direction. For a corridor intersection or an open area where people come at the sign from both sides, you need a double face unit instead.

Red letters on a clear edge lit panel. Red is the legend color required by most jurisdictions in the United States, while green is common in Canada and in some local codes, so confirm which your inspector expects before ordering a fleet of these.

Edge lit means the LEDs sit in the housing along the edge of a clear acrylic panel and light the etched EXIT legend from the side, so the panel itself looks like floating glass rather than a lit plastic box. On the Satco 67-113 the panel is clear with red letters. Pick edge lit for lobbies, hotels, offices, and anywhere the architect cares how the sign looks. Pick a standard thermoplastic housing for back of house, stairwells, parking structures, and anywhere the sign is likely to take a hit, since the molded housing shrugs off abuse better than acrylic.

Satco Lighting 67-113, also written 67/113 in Satco's own catalog format. That number covers the red on clear edge lit single face sign with the 90 minute Ni-Cad backup and 120/277V input.
