Description
The 4 plus 4 Bell monitor Board is designed to expand the
functions and Sounder and Bell output capabilities of the
Ampac FireFinder™ Fire Alarm Control Panel.
The 4 plus 4 Bell Monitor Board comes with four voltage
free changeover contacts and four switched sounder
outputs.
The four sounder outputs are monitored for short and
open circuit line conditions and the status of each output
is reported back to the FireFinder panel.
Up to eight boards can be fitted in each FireFinder panel
and each output can be individually controlled to turn on
or off via the FireFinder panel or controlled by other
FireFinder panels on a FireFinder network system.
