PAGING PANEL
In cases where Building Control System or BAS to be the domain controller including emergency voice annoucement,
it can be used to activate particular pre-recorded messages at MR1300.
The BAS would provide a close dry contact, which would activate mixer audio bypass at EP1200, as well as triggering
a message at MR1300.
The typical connection diagram is illustrated below :
Amplifiers input and output connections
Zone selector triggering connectors to TD zone decoder

As EP1200 requires a latched contact to bypass the mixer output audio, BAS system should be able to provide a
latched contact for the duration of the event.
Example, a fire sensor is activated and the BAS pick up the distress signal, it then provides a close contact, which
is then required to mute normal BGM through EP1200. In the same time, activate a warning message via MR1300.
The message shall be repeated until inspection is done and distress status is removed.
