The C-TEC FF502P is a sounder circuit extender that adds four extra monitored conventional sounder circuits to a fire alarm system. It works with most manufacturers' fire alarm control panels. When the host panel's sounder circuit activates, the FF502P's four circuits follow it. If an open or short circuit is found on any extender circuit, the fault is reported back to the host panel.
