Orbis Timesaver Base Continuity Switch

Orbis is a range with modern styling and a mounting base that saves installation time. It is electrically compatible with Apollo Series 65 and previous ranges of conventional detector. Orbis is a demonstration of Apollos commitment to the market for high quality conventional detectors for use in small to medium size installations. In developing this range Apollo has put ease of installation and reliability in daily operation at the forefront of considerations. The attractive and compact design means that Orbis will blend in well with all architectural styles. TimeSaver Base designed for fast installation StartUp for fast commissioning FasTest reduces maintenance time automatic drift compensation with DirtAlert warning to easily identify dirty detectors SensAlert which indicates that the detector is not operating properly wide voltage and operating temperature ranges optical sensor designed for high reliability and reduced false alarm incidence multisensor smoke detector for detecting fast-burning fires flashing LED option Orbis has been designed to make installation fast and simple. The E-Z fit fixing holes are shaped to allow a simple three-step mounting procedure: Fit two screws to the mounting box or surface Place the Orbis base over the screws and slide home Tighten the screws The base offers two fixing centres at 51 and 60mm. A guide on the base interior indicates the length of cable to be stripped. Five terminals are provided for the cables, four being grouped together for ease of termination. The terminals are: positive IN positive OUT negative IN and OUT (common terminal) remote LED negative connection functional earth (screen) The terminal screws are captive screws and will not fall out of the terminals. The base is supplied with the screws unscrewed in order to avoid unnecessary work for the installer. The end-of-line resistor or active device should be connected between the OUT+ and COM terminals. If it is required that all detectors be fitted with their LEDs facing the same direction the bases must be fitted to the ceiling observing the marking on the exterior which indicates the position of the LED. In many installations bases with diodes are specified in order that an active end-of-line device may be fitted. Diode bases are marked OD. Loop continuity testing is facilitated as there is a continuity device in the base. The continuity device enables power to pass through every base in a loop to ensure that each is connected correctly. Once a detector is fitted to the base the continuity device is automatically locked permanently open so that the power flows through the detectors. When the bases have been installed and the system wiring tested, the detector circuits can be populated. Two methods are suggested: 1. Apply power and fit the detectors one by one, starting at the base nearest the panel and working towards the end of the circuit. As each detector is powered up it will enter StartUp and flash red. If the LED does not flash, check the wiring polarity on the base and ensure there is power across IN+ and COM. If the LED is flashing yellow the detector is not operating correctly and may require maintenance or replacing. 2. Fit all detectors to the circuit, apply power and check detectors by observing the LED status of each device. The StartUp feature lasts for 4 minutes so it may be necessary to reset or de-power the circuit to allow all detectors to be observed. The LED status is the same as method 1.
