3 ANNOUNCEMENTS AND CONTROLS
3.1 ANNOUNCEMENTS ON THE REPEATER PANEL
3.1.1 THE REPEATER PANEL IS AT REST

No alarm or fault indicator has been activated. All LEDs are off and the built-in buzzer is not
activated.

The LCD will display the standard screen (see “4. Display information).

The MD2400 repeater panel is in rest as long as the MD2400 fire detection control panel is in
the quiescent position.
3.1.2 ANNOUNCEMENTS IN CASE OF A FAILURE

The built-in buzzer is activated.

The yellow LED “FAULT” lights up.

The name of the group to which the detector belongs, together with the detector name and
the message sequence number, appear on the LCD. The detector name is a description of a
maximum of 28 characters related to the location of the fire detector. The sequence number
indicates the chronology of the reported failure.

Alarm announcements have priority over fault announcements. If one or more alarms are
already on the LCD, an incoming fault message will initially be suppressed. With the help of the
scroll buttons “

” and “

”, the information relating to the fault messages can still be displayed
on the LCD.

General failures, such as a siren error, a power failure, a loop error and a printer error are
reported in the same way.
3.1.3 ANNOUNCEMENTS IN CASE OF A FIRE ALARM

The built-in buzzer is activated.

The red LED “ALARM” lights up.

The name of the group to which the detector belongs, together with the detector name and
the message sequence number, appear on the LCD.

The red LED “EVACUATION” lights up as soon as the set delay time has elapsed.

If the Yellow LED “EVAC. DELAYED” lights up, the delay function is active. In this case, a specific
relay (usually used to control a telephone transmitter to report the fire alarm to the fire
brigade) is only activated for a set time after the fire alarm has been triggered. The delay
function is only activated during presence (permanent presence).

If the delay function is deactivated (yellow LED “EVAC. DELAYED is switched off), then this relay
is activated immediately after each fire alarm (if this relay is connected to a telephone
transmitter, the fire brigade is called immediately). The delay function is deactivated for the
duration of the absence (no permanent presence).
