Multisensor smoke detectors are recognised as good detectors for general use but are additionally more sensitive to fast burning, flaming fires–including liquid fires–than optical detectors. They can be readily used instead of optical smoke detectors but should be used as the detector of choice for areas where the fire risk is likely to include heat at an early stage in the development of the fire.
As with Orbis optical smoke detectors the increased reliability of detection is combined with high immunity to false alarms.
The Orbis Multisensor Detector benefits from the same false alarm reduction technology as the optical detector, enhanced by the addition of a thermal sensing element.
Operation
The Orbis Multisensor detector has two sensors, one for smoke, one for heat and the alarm decision is derived from either sensor or a combination of both. The multisensor is a development of the Orbis optical detector described in the previous chapter and goes further in its capabilities of fire detection. The optical sensor is identical to the one in the Orbis optical detector. Its sensitivity is, however, influenced by a heat sensing element which makes the detector more responsive to fast-burning, flaming fires.
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.
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®, a facility which is automatically available during StartUp and which modifies algorithms so that testing is possible within 4 seconds.
Environmental Characteristics
Orbis optical detectors operate over a broad range of voltages at extremes of temperature. Thus the operating voltage is 8.5V to 33V at –40° to +70°C, a unique achievement for a conventional detector.
