Global Cache 950-0008 AC/DC Voltage Sensor

Ensure reliable power-state monitoring across your security, surveillance and AV deployments with the Global Cache 950-0008 AC/DC Voltage Sensor (GC-SP1). This compact voltage regulator-class sensor identifies on/off status by detecting AC or DC voltages above approximately ±2V and accepts voltages up to ±24V, making it ideal for power strips, wall-adapter powered equipment, ring detection on telephone lines, and remote device monitoring. The GC-SP1 is optically isolated and protected by a transient voltage suppressor to safeguard your GC-100 network adapter, iTach controllers or other TTL-input devices. It operates from a 4.5–5.5V supply with a typical draw of only ~1mA and supports AC signals from 5Hz to 5kHz, delivering dependable performance with minimal power impact. A standard 3.5mm stereo jack simplifies installation; note iTach sensor-mode use requires an audio crossover cable to swap tip and ring. Designed for professionals managing networking and physical security systems, the GC-SP1 brings low-cost, low-power monitoring to distributed installations. Add this Global Cache voltage sensor to your next security or AV project to improve uptime and streamline remote monitoring.
