- Highest reliability by optimal adjustment of the alarm threshold via intelligent algorithm for the fire detection
- Individual use of the thermal measurement according EN 54-5 in the sensitivity levels 1 to 6 as maximum detector (static --> A1S, A2S, BS) or as rate-of-rise detector with maximum threshold (differential and static --> A1R, A2R, BR)
- Individual change of detector class for sensitivity levels 1 to 6 using DPT
- Detector sensitivities automatically adapted and programmable
- Periodic sensor test
- Automatic and manual addressing on D-Loop
- Integrated isolator
- Freely programmable alarm output to control parallel indicator
- Functions completely integrated via D-Loop protocol
- Day-/Nightmode with selectable sensitivities
- Integrated event log
- Multicolour LED for alarm (red) and fault (yellow)
- LED blinking option for life signal or maintenance mode
- Delivery including dust protection cover for installation phases
