The HAES SNDEXT-4 is a general purpose sounder circuit extension card that adds 4 monitored, fused conventional sounder circuits to a fire alarm system. It is driven from an existing sounder circuit in the control panel, so it works with most makes of conventional fire alarm panel. It needs a permanent 28V DC supply, which can be taken from the 28V output of a HAES Excel-EN panel.
