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/Heat Multisensor 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)
• A sophisticated dynamic algorithm, providing transient rejection and compensation for drift whilst maintaining accurate sensitivity

Application

Fire detectors should always be installed in accordance with all local and national laws and codes of practice.

The Soteria detector can be switched between smoke and heat only modes making it suitable for a wide range of applications.

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.
