The Protec Algo-Tec™ 6000PLUS sensor range has been developed to incorporate advanced fire sensing technology, electronic sounders, high intensity LED visual alarm devices (VAD) and speech enhanced talking sounder capability, all integrated within the sensor head and powered from the loop.

6000PLUS/OPHTCO/TSVAD Interactive addressable high performance optical smoke, heat and carbon monoxide multisensor.

The ultimate in multi-sensor technology, providing a formidable weapon in the pursuit of reliable fire detection and the avoidance of unwanted or false alarms. The sensor provides total confidence that when initiated, there really is a fire threat.
The sensor incorporates infra-red light scattering for smoke detection, with thermal enhancement of the optical sensitivity, temperature detection equivalent to grade A2, and a third channel incorporating a carbon monoxide (CO) sensing element.
The combination of optical smoke, heat and carbon monoxide gas sensing technology within one fire detector head provides the ideal solution. The sensor can now detect free burning chemical fires, fires producing smoke and low levels of CO and heat, to deep seated smouldering fires, which produce little heat and smoke but large amounts of CO.
Combining the results from all sensing channels enables rapid fire detection with rejection of false alarms and increased sensor reliability.

Sensor Talking Sounder - For the ultimate method of alerting building occupants of the incidence of an emergency, the Protec Algo-Tec™ 6000PLUS sensor is equipped with an integrated voice enhanced sounder. The talking sounder is capable of delivering synchronised alert and evacuate messages around a building, removing any ambiguity, particularly for anyone unfamiliar with the building alert and evacuation strategy, enabling a more prompt and safe building evacuation.

Sensor VAD - Compliance with DDA legislation is assisted by the addition of the Protec visual alarm device (VAD) to the 6000PLUSensor, to warn those with hearing impairments or in noisy environments. The VAD utilises a high intensity LED with lower power consumption and increased reliability when compared to alternative indicators.
The VAD is located in the centre of the sensor, so can be viewed from all angles.
Suitable for ceiling mounting the VAD distributes light in a cylindrical pattern to achieve the required minimum illumination of 0.4lux over the entire coverage area in accordance with EN54-23.
The maximum mounting height is 3m with a coverage diameter of 7.5m.
For smaller areas the device can be programmed on-site for coverage diameter of 3m or 5m at reduced power.
