Apollo Soteria Tri-Sensor Detector (Dual Optical/Heat/CO) (SA5100-810APO)

The Apollo SA5100-810APO Soteria Tri-Sensor Detector (Dual Optical/Heat/CO) combines advanced dual angle smoke, heat and carbon monoxide sensors into a single algorithm which reduces the susceptibility to false alarms. It has a centrally located heat thermistor, along with a CO sensor providing three methods of detection. The detector can also operate in 5 sensitivity modes to suit various applications.

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 the 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.

Operation

The Soteria Tri-Sensor (Dual Optical/Heat/CO) detector mounts two LED indicators which illuminate red when in alarm, yellow to indicate a fault and green to indicate protocol activity.

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

The optical detection also exploits a second photo-diode receiver to take advantage of the 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 dual optical smoke sensing channels compensates for environment light and uses an enhanced dust compensation algorithm that sensibly reduces maintenance periods.

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

The CO sensing channel samples the output of the CO conditioning circuit, which exploits an electrochemical cell in order to supervise the environment level of carbon monoxide (CO).

The mixed information of optical, heat and CO detection improve both the immunity to false alarms and the early fire detection. The optical-heat-CO algorithm is based on five modes, and allows to adapt the detector performances to different application environments.

Communication

Soteria uses the new digital CoreProtocol to allow more advanced control and configuration, whilst maintaining backwards compatibility with previous generations of Apollo products – Discovery. Discovery and CoreProtocol make use of the Normal, Read and Write modes with additional nonvolatile data fields made available to the fire control panel.

Backward Compatibility

Soteria detectors have been designed to operate on Discovery loops. This allows for Soteria detectors and bases to operate on existing systems and for Soteria detectors to operate on Discovery bases (XPERT 7 Intelligent Mounting Base).
