STI GLR331ZA-EN Push Button with Key-to-Reset, Low Profile, Flush Mount, Indoor / Outdoor, Custom Text Label, White

Designed to deliver dependable, glass-free emergency activation, the Safety Technology International GLR331ZA-EN push button is a purpose-built emergency & lockdown button for facilities that require safe, tamper-resistant signaling. The Global ReSet Series offers a low-profile, flush-mount device that simulates break-glass activation but resets with a key—ideal for schools, shopping centers, food processing plants and high-traffic public areas where broken glass is unacceptable.

Installers and security managers benefit from a unit that integrates easily into alarm, access control and monitoring systems: it accepts 30V AC / 42V DC input, is constructed from durable polycarbonate, and is UL/cUL listed and ADA compliant. Upon activation an indicator drops into view for immediate visual confirmation, and the protective cover helps prevent accidental or malicious triggers. The custom text label option ensures clear instructions for staff and responders.

Use the GLR331ZA-EN to enhance emergency response, reduce false-alarm disruptions, and streamline maintenance. Pair with your security, surveillance or emergency notification setup for reliable lockdown capability — contact your distributor to specify or order today.
