STI-6580 12-Volt Heater Kit

The STI-6580 is a 12-volt heater kit that runs inside an enclosed protective cover to keep the device warm in cold weather. Two practical reasons to use it: control panels and electronics stay warm, and LEDs don't go sluggish or dim in low temperatures, so the indicator stays visible. It's temperature controlled, so it cycles rather than running constantly.

It's a 12-volt heater kit, so you need a 12V supply at the cover location. That's a separate power run from the alarm or call point circuit it sits over, so plan for it before you mount the cover on an exterior wall.

Yes. The STI-6580 kit belongs to the Stopper II and Weather Stopper family and is made to operate with enclosed covers from that line. It needs an enclosed cover to work as intended, since the heat has to be contained in the space around the device.

The pad is self-adhesive, so it sticks directly to the inside surface of the cover. No drilling, brackets, or mechanical fasteners are involved in setting the pad itself. The install work that remains is getting 12V power to it.

The reason to add the STI-6580 is cold: it keeps the protected device warm and keeps LEDs from going sluggish so they stay visible. On a conditioned interior opening there's nothing for it to solve. It earns its place on exterior walls, unheated stairwells, loading docks, parking structures, and walk-in cold storage, where the cover is enclosed and the ambient drops.

No separate thermostat is required. Temperature control is built into the kit, so it regulates itself once it has 12V power.

It's a single model, STI-6580, in a 12-volt configuration. There are no finish, size, or voltage options to specify when you order, so for a multi-site standardization program you're ordering the same part number for every cover.
