[QUOTE="pickleye, post: 281113, member: 7045"] Don't know if this helps but... When we put in fire alarms in schools, we add an interface to the fie alarm system near the (existing) door controls. The systems we are fitting have all devices on a loop detectors, call points, sounders and interfaces. We have an external company commission and program panels. Some of the modifications to older stuff have interfaces on sounder circuit. However some specifiers don't like this as if the bells are silenced the interfaces allow the doors to Lock again. As said above some get a link directly back to the panel. [/QUOTE]
