The AT-ZAP multi zone alarm has been designed specifically for use with TraceTek sensing cables (TT1000, TT1100, TT3000, TT5000, TT5001 and TT7000). The AT-ZAP can monitor per zone up to 100 m (328 ft) of sensing cable, or 10 water detection probes. Optical probes, float switches and level indicators can also be incorporated into the system. The AT-ZAP is designed for use in ordinary areas with temperatures of 0°C to 50°C (32°F to 122°F).
