Brand Information
Orbis Marine conventional fire detectors offer a wealth of features to save time, enhance reliability and reduce false alarms within the marine environment. These include drift compensation and DirtAlert®, a feature that warns Service Engineers via a flashing yellow LED that detectors need maintenance; and patented FasTest®, a procedure that takes just four seconds to test smoke detectors and confirm that they are functioning correctly.
Brand Features
Approved for use in marine environments
Modern, low-profile design
TimeSaver® Base for fast installation
Transient rejection for false alarm reduction
High humidity tolerance at up to 98% RH
Wide operating temperature -40°C to +70°C
Operation
Multisensor Smoke Detectors are recognized 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 Marine optical smoke detectors the increased reliability of detection is combined with high immunity to false alarms.
The Obis Marine multisensor smoke 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 Marine 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.
Product Information
The Orbis Marine Multisensor Detector benefits from the same false alarm reduction technology as the optical detector, with the addition of a heat sensing element.
