Loop Devices
The Protec Algo-Tec
™
 6000PLUS protocol utilises FAST
™
 addressing 
(Firmware Addressed Secure Technology). Every FAST
™
 device is 
manufactured with a unique serial number.
FAST
™
 addressing ELIMINATES troublesome and time consuming 
address cards and DIL switching whilst being far more secure than 
“soft addressing”.
The Protec Algo-Tec™ 6000PLUS sensor range has been developed 
to incorporate advanced fire sensing technology, electronic 
sounders, high intensity LED warning beacons and speech enhanced 
talking sounder capability, all integrated within the sensor head and 
powered from the loop. 
Typical Sensor Variants
6000PLUS/OPHT/S = c/w Sounder
6000PLUS/OPHT/L = c/w LED Beacon
6000PLUS/OPHT/SL = c/w Sounder and LED Beacon
6000PLUS/OPHT/TS = c/w Talking Sounder
6000PLUS/OPHT/TSL = c/w Talking Sounder and LED Beacon
