Description The keyfobs are compatible with the Bosch Solution 3000 or 4000, Bosch Wireless RF3212E Receiver, and the B810 Receiver, allowing Bosch I/P bus control panels to receive RF signals from wireless devices. Wireless devices save time for busy installers and homes, and receivers are an excellent option for system users who want more security without disrupting installations. Tamper detection, jam detection, and sensor missing status reports demonstrate that the system is operational.
