STI (EP242410-T) Polycarbonate Enclosure, 24 x 24 x 10, Tinted

The STI EP242410-T is a UL50 NEMA-rated tinted polycarbonate enclosure that protects fire alarm control panels and similar electronics from impact, weather, and vandalism. First, the polycarbonate shell resists UV and impact. Then the tinted door lets a technician confirm panel status indicators from the outside. As a result, the enclosure adds physical and weather protection without requiring the panel to be opened for routine status checks.

What EP242410-T is built for

Fire alarm control panels, remote annunciators, and other electronics often need outdoor or semi-protected installations. However, those installations expose the equipment to rain, dust, vandalism, and impact. Therefore, the EP242410-T provides a code-recognized protective shell with a tinted door so the interior LEDs and displays remain readable without opening the latch.

How the -T fits the EP242410 family

The base EP242410 ships without climate control. Specifically: -O = opaque, no climate control; -T = tinted, no climate control (this SKU); -O2 / -T2 = add A/C and heat; -O3 / -T3 = add NEMA 3R filter fan; -O5 = filter fan plus power distribution. As a result, specify the -T when the panel needs visual status confirmation through the door, the ambient environment stays within the panel’s operating range, and active climate control is not required.

Tinted vs. opaque — picking the right door

The tinted door keeps panel status indicators visible from outside the enclosure. Therefore, specify the -T when technicians need to verify power-on / trouble / alarm LEDs without unlocking the cover. Alternatively, the opaque EP242410-O blocks all view of the interior — the right choice for public spaces where panel status should not be visible to bystanders. Furthermore, opaque doors slow solar heating in direct-sun installations.
