Brand Information

Orbis® is a range of conventional detectors which has been developed and tested to create advantages for fire engineers and installers, as well as owners and users of buildings. 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 Apollo’s 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. Orbis is manufactured in Apollo’s factory near Portsmouth, England Orbis has been tested and approved to the following standards: EN54–7: 2000 + A1: 2002 optical smoke detector EN 54–7: 2000 + A1: 2002 & CEA 4021: 2003-07 multisensor smoke detector EN 54–5: 2000 + A1: 2002 heat detector Detectors have been declared as being compliant with the essential requirements of the EMC Directive 2004/108/EEC and the Construction Products Directive 89/106/EEC

Operation

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.

Application

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.

Maintenance & Service

Detectors should be checked regularly at the intervals indicated by the locally applicable code of practice. Apollo recommends that detectors be checked at least once a year. One of the features of Orbis is FasTest® which makes it possible to carry out a functional test, using smoke or heat, within about four seconds. If detectors appear not to be functioning correctly they should be returned to Apollo for testing. If detectors are externally dirty they can be cleaned carefully with a damp cloth sing a small amount of industrial alcohol. DirtAlert™ Orbis detectors have drift compensation to compensate for changes caused by the environment. The most usual change is contamination. If the detector is dirty to the point where it can no longer compensate, its LED will flash yellow while it is in StartUp. Maintenance checks should therefore include removing a detector from its base and re-inserting it or pressing reset on the panel to imitate StartUp. A flashing yellow LED is not a sign that the detector needs to be replaced immediately. The decision to replace should be taken by the service engineer, taking the environment of the detector into account. If the detector is not replaced it will eventually cause false alarms. When deciding how long to leave the detector on site in such a case, the following rule of thumb may be used: installation time + 25%. For example, if a detector had been installed for four years when the LED flashed yellow, it could be left in place for up to 12 months. Dirty detectors can be returned to Apollo for cleaning and re-calibration.

Additional Information

Orbis has been designed with a number of features that make commissioning easier and that save time. StartUp When Orbis detectors are powered up they automatically enter a phase known as StartUp and in which they stay for 4 minutes. After this they revert to normal operation. If the detector is reset, ie, if power is disconnected for one second or longer, the detector will always enter StartUp for the first four minutes after power has been restored. The detector LED flashes red once a second to indicate that it is in StartUp. What StartUp indicates StartUp is used to check that the positive and negative cables are connected in the correct polarity and that power has been applied to the detector. If this is the case, the LED will flash red once a second. StartUp will not check whether the IN+ and OUT+ connections have been transposed. This is not a problem if standard bases are used as the detector will operate normally. If, however, diode bases are used and a detector is removed from a base with transposed positive connections none of the detectors beyond this point will operate. FasTest® Orbis detectors incorporate a test facility known as FasTest®. In normal operation Orbis smoke detectors do not change to the alarm state at the first sensing of smoke. If they did, they could be too sensitive and cause false alarms. Algorithms determine the point at which the detector changes to alarm. This could slow down routine maintenance during which detectors are tested by means of smoke or a smoke-simulating substance. In order to avoid such a problem Orbis detectors have FasTest, a facility which is automatically available during StartUp and which modifies algorithms so that testing is possible within 4 seconds. The problem of testing is even more acute in the case of heat detectors as they absorb a great deal of heat during testing. Orbis heat detectors also incorporate FasTest®. In the case of heat detectors a fast test is defined as a sample which recognises a rise of 10°C within one minute. Since sampling takes place every 2 seconds an Orbis heat detector will respond within about 4 seconds. Smoke or Heat Testing Smoke or heat testing Orbis detectors is aided by the FasTest® feature. A detector will react rapidly to the correct stimulus if applied within 4 minutes after power up. Choose the appropriate test function on the control panel and reset the detector circuit. This should place the detectors into FasTest®. Apply smoke or heat as appropriate and the detector should enter the alarm state within 4 seconds. The panel may sound the alarm and reset the zone automatically (refer to control panel’s instructions). If not, silence the alarm and reset the panel. Repeat the procedure as necessary. Note that the multisensor detector will respond to either smoke or heat while in FasTest®.
