(minutes:seconds) indication. Before this delay
counts down to 0, press the INVESTIGATE control
key.
Note: You now see an Inv mm:ss (minutes:seconds)
countdown of the remaining investigation time. The
countdown updates in 5 second steps. Once the
countdown reaches 0 the signalling activates.
4 You can now determine the cause of the alarm and
carry out the necessary measures.
Note: You can investigate any other current events
using the More and All function keys, as you can
with non-alarm events. For more information see
steps 1 and 2 in section 2.6 “Event operator actions“
on page 9.
5 If you confirm there is a fire, you can override the
delay and activate signalling by pressing the
EVACUATE control key, if applicable, or by activat-
ing a call point.
6 If you determine there is a false alarm, you can reset
the control panel, as described in section 2.8.6
“Resetting the panel“ on page 14.
2.8.2 EVACUATE control key
With the Enable keyswitch set to 1 (ON), pressing the
EVACUATE control key will produce the same
response as an alarm. See 2.7 “Alarm panel behaviour“
on page 10.
Note: If your panel does not have an EVACUATE con-
trol key, activate a call point instead.
2.8.3 Silencing the sounders
You can optionally silence the sounders using the
SILENCE/RESOUND key without affecting any other
alarm conditions. This is not permanent, as you can re-
activate the sounders if necessary.
Alternatively, if available on your panel, press the
SOUNDERS ON/OFF control key to enable or disable
the external sounders. If the SOUNDERS ON/OFF con-
trol key is set to OFF, the sounders will not resound if a
new alarm occurs.
Silencing the sounders
1 Insert the key into the Enable keyswitch, and turn to
the 1 (ON) position.
2 Press the SILENCE/RESOUND key.The system
responds as follows:
– The sounders are silenced.
– The (SOUNDERS)
LED is unlit.
– All other outputs remain activated.
– The LCD display remains on and shows the alarm
type and the complete zone identification.
– A Sound SIL message appears.
3 If you need to re-activate the sounders, press the
SILENCE/RESOUND key again.
2.8.4 Clear a system fault on panel

tem fault, follow this procedure to clear it.

and display a boot screen.

buzzer sounds. Press the SILENCE BUZZER key on
the panel to disable the buzzer.The initialisation
countdown continues to 0.
