detects radio signals and generates an alarm message.
6. "Radio Fire Alarm Receiver" is a system that
receives fire alarm signals, displays, and records
the alarm messages. It may simply listen for any
alarm messages (one-way data transmission) or it may
sequentially transmit a radio signal asking each
(two-way data transmission).
When an addition to an existing system is required,
provide the make, model number, and other pertinent
information to the designer. This will eliminate
most of this specification because the additional
interfaces have to be compatible with the existing
central radio fire alarm reporting system.
