Description
High performance Cost effective Scalable UL-Listed Primary Signaling
Keltron RF774F wireless transceivers provide two-way alarm transmission from monitored locations to the supervising receiver. Replacing expensive and unreliable telephone lines, active network radio is a self-routing and self-healing solution that ensures instant life safety event monitoring over a wide geographic area.
Designed for use in campus facilities, industrial complexes or municipal environments, each Keltron RF774F wireless transceiver serves as both a transceiver and a repeater to improve the strength and range of the entire network. The two-way transceiver provides high integrity communications that ensure every signal is authenticated and acknowledged.
Keltron RF774F wireless transceivers feature 8 discrete programmable inputs, 4 reverse polarity (RP) and 4 end-of-line (EOL) inputs.
Keltron develops and manufactures universally-compatible, UL listed life safety event management systems for the municipal and proprietary markets. Solutions include Ethernet signaling systems, active network radio systems, distributed multiplex systems, digital communicator/receiver systems, and direct wire systems.

Features
The Keltron active network radio system is UL-listed as a Primary Signaling System. This means that it may be used as the sole method of transmitting fire alarm signals to the receiving location. Other key features include:
- 4 reversing voltage inputs, optically isolated for maximum ability, programmable for reversing relay type fire panel outputs (RP)
- 4 programmable zone inputs for general alarm applications, (EOL)
- Built-in power supply and battery charger
- Digital dialer input using the IntelliTap receiver to tap the alarm panel dialer output and transfer full alarm data by radio
- Alternate input module, DataTap™ RS232 interface to addressable FACP
