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.\u003c\/p\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eStopper II door alarm configuration without an integrated horn\u003c\/li\u003e\n\u003cli\u003eIncludes spacer for mounting clearance over door hardware or uneven surfaces\u003c\/li\u003e\n\u003cli\u003eFire label included for code-visible door identification\u003c\/li\u003e\n\u003cli\u003eCompact, self-contained form factor for surface mounting at door locations\u003c\/li\u003e\n\u003cli\u003eSuited for commercial, institutional, and light industrial exit door applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct installation unit for standard commercial exit door alarm applications requiring a hornless Stopper II configuration with spacer.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a licensed electrician or certified fire alarm technician in accordance with NFPA 72 and applicable local codes.
