Apollo Soteria Smoke & Heat Multisensor Detector c/w Isolator - SA5100-700APO

The Soteria Optical/Heat Multisensor Detector uses new optical sensing technology, PureLight®, to detect smoke particles entering the chamber and is fitted with two thermistors for detecting heat. It can be switched to detect smoke, heat or a combination of both offering greater flexibility.

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

In addition to the optical smoke sensor, the Soteria Optical/Heat Multisensor Detector uses dual temperature sensors for improved reliability and is responsive in all detector orientations.

The independent signals from the optical smoke and heat sensors are combined in the detector microprocessor to produce an alarm decision according to the response mode chosen. With reference to Table 1, the five modes provide response behaviour which incorporates pure smoke detection, pure heat detection or a combination of both. The mode of operation of this processing is selected at the fire control panel.

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.
