Two Way Wireless Door/Window Magnetic Contact

The FW2-MAG is an advanced magnetic contact sensor with integrated RF transceiver designed to be a fully supervised low-current device. A built-in reed switch and/or an external wired input may be applied in this device. To maximize security, an 8.2K end-of-line resistor is monitored on the external wired input. FW2-MAG uses smart message control, which verifies that all messages are successfully transmitted, so that no intrusion event will be uninformed to the system. Each FW2-MAG has a unique factory set ID code (24bit) which by registration is set into memory of the paired Freewave2™ Transceiver, enabling more secured communication and devices to be remotely controlled from a specific transceiver.

How can you use a wireless device with FLEXi SP3 smart alarm control panel?

RF-SH wireless expander interface

By connecting an RF-SH wireless expander interface you can use the "classic" wired alarm system as a hybrid or wireless. Comes handy when you have no option to lay wires and need wireless sensors or other equipment.
