The FW2-MAG-9F is an advanced fully supervised detector with, low current with 2-way communication with the alarm panel, that includes an advanced RF protocol for a secure and reliable system operation. The 2-way transmission allows that the sensor obtains a response from the panel to avoid repeating the event transmission (aperture or tamper), this way will reflect a prolonged battery charge time. Each FW2-MAG possesses an ID code that is unique and factory programmed (24 bits), that its registry establishes in the TRANSCEPTORS memory. Characteristics: -For door or window. -Technology @ 916 MHz. -Operates with a lithium battery. -Auxiliar battery for connection of dry contact sensors. NOTE: For its implementation in the Runner Panel an FWTRANS9F transceiver is required. Not compatible with FWRCV.Key Features Advanced Two-Way RF Protocol for Secure System Operation Bidirectional Transmission for Enhanced Energy Efficiency Factory-Programmed 24-Bit Unique Identification Code 916 MHz Technology for Reliable Wireless Communication Lithium Battery for Extended Operational Lifetime Auxiliary Output for Dry Contact Sensor Connection
