STI STI-13210FR-ES Universal Stopper Surface Mount
Overview
The STI-13210FR-ES is a surface-mount protective enclosure designed to shield fire alarm pull stations, emergency intercoms, numeric keypads, and other critical access-control devices from vandalism, accidental damage, and environmental contamination. This model lacks an integral horn, making it suitable for installations where the protected device already includes audio capability or where silent activation is preferred. The fire-label variant (red housing with "In Case of Fire" marking) ensures rapid identification in emergency situations while maintaining ADA low-profile compliance. Powered by 24VDC, the unit integrates into standard building security and fire-safety systems.
Compatibility
The STI-13210FR-ES works with any surface-mounted fire alarm station, intercom, keypad, or emergency button that fits within its internal cavity and draws power from a 24VDC source. It is compatible with both hardwired 24VDC access-control systems and integrated fire-safety networks that supply this voltage. The surface-mount configuration accepts standard electrical conduit (¾" rigid conduit), allowing flexible integration into existing wall-mounted access-control infrastructure. Verify device dimensions against the internal cavity before purchase to ensure your specific alarm station or intercom fits.
Installation Notes
Mount directly to wall or door frame using supplied hardware; internal water-tight mounting plate is sealed to prevent dust and moisture ingress. The polycarbonate cover hinges on a full-width, high-strength hinge and includes a locking tab (not suitable for fire alarms per code). UV-stabilized material resists yellowing and maintains transparency for inspection. Sealed gaskets are included; no additional weatherproofing material is required for interior or exterior mounting. Wiring passes through the ¾" conduit knockouts at the base. Confirm local fire code permits the fire-label variant in your jurisdiction before installation.
