Knight Grade 2, Surface Shock/Tilt Sensor with Integral Resistors
SEISMO is a shock/vibration sensor also capable of detecting tilt movement of the surface it is mounted on. This unit requires a 12V supply to operate correctly. Tamper protection is provided by a microswitch tamper, which detects when the lid is removed. The circuit is also run around a PCB fitting hole. The PCB will snap when the unit is pulled from the surface, providing back tamper protection. This detector comes complete with integral resistors, configured by shunt selection: EOL Resistors: 1k, 2k2, 4k1, 4k7, 5k6. Alm Resistors: 1k, 2k2, 4k1, 4k7, 5k6, 6k8. These resistors cover the majority of leading panel manufacturers including Honeywell, Texecom, HKC, Risco etc. Use of the resistors is optional. LED output displays detections for both stimuli (blue for vibration, green for tilt), alarm output, low power and a comfort light. Calibrated at the point of manufacture, most can be fitted with the default sensitivity in place. A recalibration function is available on the PCB. SEISMO can be configured to alarm on vibration only (supporting a pulse count), tilt only, tilt/vibration or tilt+vibration. Fitting screws are provided for immediate installation from the package.
