AJAX 42802.79.WH3 Double Button Wireless Hold-up Transmitter, White

Protect people and property with the AJAX Double Button wireless hold-up transmitter — a compact panic button engineered for fast, dependable emergency signaling. This AJAX hold-up & panic button sends instant alerts to your security monitoring system using the Jeweller two-way radio protocol, with a wireless range of up to 1300 m to ensure coverage across most sites. Built-in encryption and anti-tamper logic reduce false alarms and prevent device spoofing, while automatic fallback to a free radio frequency keeps alerts flowing during network interference. The IP55-rated housing and a clear LED confirmation make installation and daily use straightforward for commercial installations, retail, healthcare and multi-tenant buildings. Compatible with Ajax hubs and range extenders running OS Malevich 2.10 or newer, it can also trigger auxiliary responses — sirens, electric locks, shutters — so your security or surveillance system can respond automatically. Specify the AJAX Double Button as part of your intrusion monitoring and emergency response plan to strengthen safety protocols and accelerate incident handling. Add to your security setup today for reliable panic protection.
