STI STI-14020FR Low Profile Universal Stopper with Horn
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.
Compatibility
The STI-14020FR integrates with STI fire-rated enclosure systems and intercom notification infrastructure. Flush-mount configuration fits standard electrical and life-safety device cutouts. 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.
Installation Notes
Mounting: Recessed (flush), surface-mount, or weatherproof options available with internal sealed or open mounting plates. ¾" rigid conduit threads on top and bottom of weatherproof housing for code-compliant conduit entry. Includes gaskets for environmental sealing. Low-profile design fits ADA-compliant installations. Polycarbonate construction is UV-stabilized to maintain clarity in outdoor exposure. High-strength integral hinge rated for frequent access cycles. Optional relay output accommodates 12–24VDC external circuits. No lock tab should be used on fire alarm stations per safety standards.
