Page 2: General Description
2-12 sense zones (detector zones). The Terofire 12 is provided with 4 alarm zones (bell zones) while the other panels in the range have 2 alarm zones. All Terofire Plus panels have a one man test facility, class change input, fault output and two sets of volt free changeover contacts which operate on fire. - Page 3 Detector Head Removal The Terofire Plus range supports head removal. The basic principle of head removal is to ensure that all call points will function even if a detector head has been removed. When a detector head is removed, the panel will show a fault but the sense zone circuit will remain intact.
