Electrical Description
The Soteria detector is designed to be connected to a two-wire loop circuit carrying both data and power. A version with a short-circuit isolator integrated into the detector head is also available.
Operation
The low profile design of the Soteria Optical Smoke Detector is sleek and evolutionary, with a 360° LED indicator which illuminates red when in alarm, yellow to indicate a fault and green to indicate protocol activity. At the heart of the Soteria detector is PureLight Sensing Technology which incorporates: Cone technology combined with a high-intensity infra-red LED to provide stability and accurate sensitivity to smoke A photo-diode and an amplifier integrated into an Application-Specific Integrated Circuit (ASIC) 'Serpentine' pathway designed to provide a barrier against dust and insect ingress A sophisticated dynamic algorithm, providing transient rejection and compensation for drift whilst maintaining accurate sensitivity The sensitivity mode of operation of this processing is selected at the fire control panel.
Application
Fire detectors should always be installed in accordance with all local and national laws and codes of practice. Optical smoke detectors are recommended for general use, particularly where there is a risk of slow burning fires or where the development of smoke could become the major hazard.
Device Addressing
A universal XPERT 8 card is supplied with all XPERT 8 Intelligent Mounting Bases. Using a coding guide, pips on the card are removed to set the address of the detector. This simplifies and speeds up installation, commissioning and maintenance. The address location remains the same no matter how often detectors are replaced. When Soteria devices are used with CoreProtocol, device auto-addressing can be enabled by fire control panels that have been designed to incorporate this feature.
Communication
Soteria uses the new digital CoreProtocol to allow more advanced control and configuration, whilst maintaining backwards compatibility with previous generations of Apollo products - XP95 and Discovery. Discovery and CoreProtocol make use of the Normal, Read and Write modes with additional non-volatile data fields made available to the fire control panel.
Backward Compatibility
Soteria detectors have been designed to operate on XP95 and Discovery loops. This allows for Soteria detectors and bases to operate on existing systems and for Soteria detectors to operate on XP95 and Discovery bases (XPERT 7 Intelligent Mounting Base). It should be noted that not all features of Soteria will be available when used with XP95 or Discovery fire control panels. If Soteria detectors are used with XP95 fire control panels incorporating drift compensation algorithms, these must be disabled when communicating with Soteria devices. When Soteria detectors are used with an XPERT 7 Intelligent Mounting Base on a CoreProtocol system, Soteria devices will have a +128 address offset due to only 7 address pips being available on the XPERT 7 card. For example, an XPERT 7 card set at 32 will address as 160 on CoreProtocol with Soteria detectors.
