Wireless smoke alarm set Komfort Q, 3x TG550A, IR alarm stop, white. Wireless smoke alarm package consisting of 3 TG550A with small size and attractive design language according to DIN EN 14604 with additional certification according to the increased test requirements of the Q certification based on the vfdb guidelines 14-01 (Association for the Promotion of German Fire Protection). Increased test criteria against the penetration of foreign bodies and increased protection against damp heat, oxidation and EMC, as well as better thermal cycling. Serves for the early detection and signaling of fires with smoke development in the interior of apartments or apartment-like areas, as well as mobile homes, caravans and camper vans. Can be installed as a single device or as a wireless network with up to max. 40 detectors with additional activation of any detector in the wireless network as a repeater to increase the range. The radio network can be set up without tools using push-button mode and can be checked using the integrated range indicator using LEDs. Patented alarm stop using any manufacturer-independent IR remote control, by pressing the detector button or optionally using the radio network with a radio pressure button TG558B alarm stop. Manual alarm triggering is optionally possible by integrating a radio pressure button TG558A for the house alarm. Optional control of external signal or peripheral devices using the RXA005X relay socket. Processor-controlled function self-test of all relevant components (every 10 seconds) and PGSA technology with independent algorithmic sensitivity adjustment in the event of interference such as dust to maintain functional reliability. Large function and reset button with integrated white light cone in the event of fire and during the test alarm. Acoustic signal (85 dB at 3 m) and red flashing LED for alarm. Acoustic signal for low battery, contamination or fault messages with acoustic signaling and yellow LED. Time-limited deactivation function of the smoke detection to suppress false alarms from the detector for approx. 12 minutes with automatic reset function to normal operation. Nighttime sleep function to delay fault messages until the day. Fault messages can be suppressed for a further 8 hours by acknowledging the reset button. The fault of a dirty detection unit/detector head cannot be reset as long as the false message is still being analyzed in the evaluation unit. Disassembly and theft protection can be activated, after which unlocking is only possible by turning a screwdriver with a maximum size of 7 mm. The detector is automatically activated when screwed into the base. Battery life of at least 10 years using an encapsulated lithium battery.
