Sti sti-1230 Stopper Ii Door Alarm Without Horn Spacer

Product Description

The STI sti-1230 is a Stopper II door alarm unit designed for fire egress and unauthorized exit monitoring applications. This model ships without a horn and includes a spacer for proper mounting clearance, along with a fire label for code-visible identification. It mounts directly to a door or nearby wall surface and triggers an alert when the protected door is opened without authorization. The sti-1230 is a compact, self-contained device suited for installation by commercial electricians, fire alarm technicians, and facilities maintenance professionals in light commercial and institutional settings.

The sti-1230 is typically used on interior exit doors in commercial buildings, schools, healthcare facilities, and similar occupancies where unauthorized egress must be deterred or monitored. The spacer accessory allows the unit to clear door hardware or uneven surfaces during mounting. Because this model does not include a horn, it is intended for use in installations where a separate audible device or panel integration handles the alarm output, or where a visual-only indicator is preferred at the door location.

Installation Notes

Installation is typically performed by a licensed electrician or certified fire alarm technician in accordance with NFPA 72 and applicable local codes. Disconnect or de-energize the door alarm circuit before mounting or wiring the unit. Ensure the spacer is properly seated before securing the housing to prevent stress on the mounting surface. Consult the authority having jurisdiction regarding fire egress door alarm placement requirements prior to installation.
