The FDOT100 optical heat detector analyses air and temperature in the protected area in order to promptly trigger the fire alarm if necessary and, at the same time, offer a high protection level against false alarms. The alarm condition occurs when:
- the smoke quantity in the optical chamber exceeds the alarm threshold
- the temperature or the thermal variation within a certain time frame exceeds the alarm threshold. In one of these conditions, an alarm message is sent to the MC100 module which reports it to the fire detection control unit connected to it. The alarm signal can reach the MC100 module directly or through one or more ESPMC100 addon modules. The latest generation openings for smoke entry into the optical chamber ensure a very high protection level against dust penetration, increasing the interval between maintenance operations. The communication between the input module and MC100 and ESPMC100 modules takes place in radio mode through a bidirectional protocol.
