Overview
The STI-14020FR is a low-profile polycarbonate protective enclosure for flush-mount installation protecting manual fire alarm stations, keypads, intercom stations, emergency buttons, and electrical switches in indoor and outdoor environments. The integrated horn output (models available with 105 dB sirens) and fire-rated label meet life-safety signage requirements. Operating voltage is 24VDC with optional relay output. The dome form factor and low-profile design comply with ADA accessibility standards.

Confirm mounting plate compatibility and 24VDC power availability in your access control and audio notification architecture before deployment. Compatible with existing STI stopper product families in low-profile, dome, and flush mounting configurations.
