15.0 Appendix A, RVAV Description
• Availability: RVAV is available on loop devices that have a ‘Fire LED’.
• Format : When the device receives the signal to RVAV, it outputs its address in the
following format:-
The address is output as hundreds, tens and units with a one and a half
second delay between. If the address is less than 100 then the leading zero for
the hundreds is not output. The address is determined by counting the LED
flashes. A zero is denoted by a long flash of approximately one second. There
is a half second delay (approx.) between LED flashes.
