The SAFETY TECHNOLOGY INT'L INC SS2435XT-EN is a blue monitor illuminated stopper designed for use in fire alarm and life safety systems. This device serves as a pull station stopper with built-in illumination, providing a visible deterrent and indicator at manual pull station locations. It is typically installed by licensed fire alarm technicians or electricians working within commercial and institutional fire protection systems. The illuminated design allows for quick visual identification of the pull station location, supporting both routine inspection and emergency response.
The SS2435XT-EN is suited for commercial, institutional, and light industrial applications where manual fire alarm pull stations require a monitored stopper with indicator lighting. It is categorized under pull stations and is sold as an individual unit. Installation scenarios typically include schools, office buildings, and other facilities where pull station tampering prevention and clear visual identification are required by code or facility management.
Designed as an OEM-style replacement or add-on stopper for compatible manual fire alarm pull stations. Consult the manufacturer data sheet for confirmed compatible pull station models before installation.
Installation should be performed by a licensed fire alarm technician or qualified electrician in accordance with NFPA 72 and all applicable local codes. Disconnect and lock out power to the fire alarm circuit before servicing or replacing any pull station component. Verify wiring polarity and monitor circuit connections per the manufacturer wiring diagram. Do not place the panel in alarm condition without notifying the monitoring station and building occupants.
