The Mircom TC-330U is a flush-mount enclosure cover with a key-locked door and break-glass insert. It houses Mircom emergency telephone handsets used by firefighters and building wardens.
First, the steel cover sits flush in the wall behind the lock plate. Then, in an emergency, a responder breaks the glass and pulls the handset out. As a result, the protected handset stays inside until it is actually needed.
Mircom TC-330U Key Features
- Heavy-gauge steel cover, red finish
- Flush-mount installation against the matching TC-330 back box
- Keyed-alike door lock for tamper resistance
- Break-glass insert preserves the handset until an emergency
- English markings (US/EN model)
Where It Fits
The TC-330U pairs with Mircom’s fire-warden phone handsets and TX3 voice entry installations. Specifically, you’ll find it in stairwells, elevator lobbies, and firefighter recall zones. Therefore, fire alarm contractors keep the TC-330U on the truck for damaged-door swap-outs.
