This is a basic single-zone system that features the CT-2B/G control unit with single timed output and simplified features. Four sensor probes may be attached in series to the control unit(s). Control unit is capable of operating twelve annunciators. Adjustments include probe sensitivity and relay time. Includes manual trip test button, retrigger hold-off, and transient suppression (that can be disenabled). Comes with 12 volt transformer. Direct burial cable on sensor probe is custom cut in lengths of 50 feet to 3,000 feet or more (for splicing purposes, a probe with 10 feet of cable is available). The length of cable does not affect probe sensitivity. No conduit is required, though it may be used. Cable is fully shielded and may be placed in same conduit as power and telephone lines. Cable is covered with polyurethane and may be spliced with an available epoxy splice kit. Four different annunciators may be used with this system: CT-8, CT-8A, CT-9A, CT-11
