Keltron's PET401 is one of a series of distributed-multiplex addressable transceivers that provide a low cost and reliable method of protecting a wide range of proprietary, commercial, and industrial buildings and complexes.
The PET401 is especially appropriate for use in campus environments and industrial complexes because the module and the FACP may be located up to several miles apart when using an optional modem.
Reliability - high-performance error-detection during serial, multiplexed signal transmission
Low cost - retransmits serial data output from the FACP with cost-saving wiring flexibility
Compact and easy to install
Contains both serial alarm input RS-232C and full RS485 signaling circuit capability
Branching minimizes wiring and allows miles of distance capability
Wide range low power input - 8-24V at 75mA
NFPA 72 signaling line circuit classes A or B to style 7
