Emergency Voice System Operation

11-4

The user at the second LOC requests EVS Control from the LOC with EVS Control and that LOC grants the
request. (See Section 11.2.7). If the EVS lockout timer expires while an EVS Control request is in progress,
the system will automatically pass EVS Control to the requesting LOC.

The user at the second LOC enters an access code with the EVS Super User profile option.

The LOC lockout timer can be set between immediate and 12 hours in increments of 1 second or it can be set to
never expire. The default setting is 30 seconds. The LOC lockout timer is restarted upon any key press at the
LOC with EVS control. The LOC lockout timer is cleared when EVS Control is relinquished.

11.2.2.3 User Profile Access Control

The user will need to enter an access code containing the EVS Control Request or EVS Super User profile option
to gain EVS Control. EVS Control Request and EVS Super User profile options will be mutually exclusive to the
system. If the access code has EVS Super User, the EVS Control Request is ignored and activations by that user
are always as EVS Super User.

11.2.3

Manual EVS

After gaining EVS Control the system enters the LOC EVS interface which allows you to activate the
Emergency System and allows for Emergency Paging. Once an emergency event has been activated the panel
enters a Manual EVS State. In this state, all EVS Alarm programmed points that are currently in alarm in the
system are changed to an active state. The display status screen reflects this when viewing the system for status.
Any outputs that were activated by the EVS Alarm programmed points are deactivated until Manual EVS state is
exited. Only an EVS Reset can exit the Manual EVS State. If a user gains EVS Control at an LOC and does not
activate an EVS message, the system will automatically generate an EVS Supervisory indicating such. This
prevents an LOC from being in an undesired state of EVS Control when an actual event emerges.

There are two modes for interacting with the LOC EVS interface when in Manual EVS State:

Message Mode

Microphone Mode

These two modes allow you to quickly toggle areas of output for a desired message or to speak to a microphone
for EVS Paging.

After gaining EVS Control, the system is in Message Mode of the Manual EVS State.

11.2.3.1 Switching between Microphone Mode and Message Mode

At any time while in EVS Control, you can switch between Microphone Mode and Message Mode. Microphone
Mode is entered by simply engaging the microphone.

Message Mode: Use the EVS Message keys to toggle which message/event to output to the system. Use the
Select Keys to toggle output areas to play the current EVS Message in. The Select Key's red LED will toggle
on/off with the activation/deactivation of the area is now receiving the message. Any non-voice groups
assigned to this Select Key will also toggle with their Activation Cadence. See Section11.2.3.2.

Microphone Mode: Use the Select Keys while the microphone is active to toggle which areas to do an EVS
Microphone Page to. The Select Key's green LED will toggle on/off with the activation/deactivation of the
EVS Microphone Page to the area.

11.2.3.2 Activating Output Groups Dynamically

This method allows the system to be setup with minimal or no system mapping. When in Manual EVS State and
operating in Message Mode the user can dynamically activate/deactivate output areas for system notification to
take place in. The Select Key red LED will become lit and the circuits in the output group(s) will become active
