ABUS Terxon SX Wired Alarm System Control Panel with 8 Zones and Integrated PSTN Dialer

For a small shop owner who needs dependable intrusion detection without complex networking, the ABUS Terxon SX wired alarm panel delivers straightforward protection. This control unit manages up to 8 hardwired zones, each supporting normally closed, normally open, or end-of-line resistor configurations, making it compatible with a wide range of door contacts, motion detectors, and glass break sensors. The metal housing includes a dedicated tamper zone to alert you if someone tries to open the panel. Three programmable outputs let you trigger external devices like strobes or additional sounders, while the integrated PSTN dialer can call up to four phone numbers to report alarms. With support for up to 8 user codes and 4 wired keypads, it suits homes and small businesses that need multiple access levels. The panel runs on 230V AC mains and accepts a 12V backup battery (not included) for continued operation during power outages. Its 250-event memory helps you review recent activity, and the optional IP module allows future expansion to network monitoring. Certified to VdS Home standards, this panel is a solid foundation for a basic wired security system.
