Apollo Soteria Multi-Sensor Detector (Dual Optical/Heat) (SA5100-710APO)

The Apollo SA5100-710APO Soteria Multi-Sensor Detector (Dual Optical/Heat) uses advanced dual optical sensing technology to accurately detect smoke particles entering the chamber and a central heat thermistor for detecting heat. It has five different operating modes, giving you the option to adapt the detector to suits it environment.

Operation

The Apollo SA5100-710APO Soteria Multi-Sensor Detector (Dual Optical / Heat) mounts two LED indicators which illuminate red when in alarm, yellow to indicate a fault and green to indicate protocol activity.

The photo-electric smoke sensing channel works on a light scattering-Tyndall effect basis: an IR emitter–receiver pair (LED and photodiode) is placed in a smoke chamber, designed to have high immunity to environment light and dust settling.

The optical detection also exploits a second photodiode receiver to take advantage of the dual angle scattering information to improve the capability to reject nuisance related signals.

Proper amplification and data processing is applied to the signals to discriminate transient signals, noises, etc from real fire and dangerous situations. The optical smoke sensing channels compensates for environment light and uses an enhanced dust compensation algorithm to sensibly reduce maintenance periods.

The heat sensing channel exploits a single, centrally positioned, NTC thermistor which supervises the environment temperature.

The mixed information of optical and thermal detection gives an high immunity to false alarms, increases sensitivity in case of temperature raising and allows the product to achieve multiple criteria photo-thermal detection. The dual optical/heat algorithm is based on 5 modes, and allows to adapt the detector performances to different application environments.

Communication

The Apollo Soteria range uses the new digital CoreProtocol to allow more advanced control and configuration, whilst maintaining backwards compatibility with the previous generation of Apollo products – 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.

Device Addressing

The addressing method will not be using the XPERT Address card, instead, it will be through soft addressing or a DIL switch on bottom of the detector.

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.
