Power Distribution Frame Upgrades; Office Alarm System Features - Nortel DMS-100 Series Reference Manual

4-10 Version 2 Enhanced Alarm System
allows the addition of up to ten additional exit alarm panels to the alarm
system.
The extension circuit permits selective control of the audible alarm panels.
You require control when audible alarm panels are configured with the
audible alarm cutoff control circuit (NT5X86AA) and the audible alarm
cutoff key panel (NT5X86AB). The audible alarm cutoff key panel is
located at the MAP terminal. The audible alarm cutoff key panel allows you
to selectively disable the two main audible alarm panels and the four
extended audible alarm panels. Figure 4-6 shows the audible alarm cutoff
key panel.
When you extend audible alarm capability, a ringing generator must be
available for the extension circuit.
