I have 10 pieces of these smoke detectors (consisting of 1x and 1x Mumbi RMF104 RMF106) ordered, 5 each for a building. They are put together in groups of 4 plus 1 Slave Master. The 2 buildings (1x truss structure; 1x Solid construction with reinforced concrete floors) are multistory, me it is especially important to cover all escape routes. Networking works on all three floors, from the basement to the top floor (building 2 has solid floors). The interior of the smoke detector works fairly straightforward (earplugs are recommended), if one reads the instructions properly.
here briefly the procedure: Pick from a master smoke detectors. In this press the LEARN key until the device is green. From now on, you have 20 seconds to connect all slave devices. In the SLAVES, smoke detectors be sure to press the Learn button until it lights red. Now you stick to the MASTER smoke alarm down the TEST button until all smoke detectors trigger an alarm signal (run all about 1 minute and then switch off). Press now any smoke detectors the TEST button (whether master or slave). The alarm sounds. All other devices emit an alarm sound and the LEARN LED will flash green.
Important: Please do not post the programming of the devices change / remove the batteries, as this programming is affected. Should any error in programming the devices arise, please remove the batteries from all units. Wait before making the reprogramming requires a minimum of 3 minutes.
Price / performance is unmatched! The delivery by Fa. HandyNow food was very quick and without any problems! I can recommend the smoke detector absolutely!
