IT-400 series instruction manual
ENGLISH
To disarm the panel
:
IT-400 : Rotate the key in “
DAY
” position.
IT-400 K : Insert the key into the key holder for less than 5 sec.
IT-400 D : Digit the access code on a keypad and press “
#
”.
The panel will disarm
. The LED “
ON
” or “
NIGHT
” will
go off
.
If while armed, an alarm has been triggered, when the control panel is disarmed, the LED
of the triggered zone will flash until the control panel is again armed. This indicates "Alarm
memory".
To cancel the alarm memory in IT-400 D / IT-400K, press any key on the keypad or change
the status of the control panel by first arming and then disarming the control panel.
To cancel the alarm memory in IT-400, it is sufficient to change the status of the control
panel by rotating the key before in "
ON
" position and then in "
DAY
" position.
16.0. DISARMING
(DAY mode)
1)
The unbalancing of the 24 hour zone (Terminals 28 and 29), the sabotage of zones L1
L4
and the inserting of false electronic keys will cause
:
- Slow flashing of “
24 H
” LED on the panel. The LEDs will remain active until the next
arming of the panel to indicate “Alarm memory”.
- The activation of the indoor and outdoor siren alarm relays (Terminals
9 to 17) for the
time that has been programmed.
2)
The unbalancing of the fire zone (Terminals 25 and 26) causes
:
- Slow flashing of the “
FIRE
” LED on the panel. The LEDs remain active until the next
arming of the panel to indicate “Alarm memory”.
- The activation of the fire alarm relay (Terminals 3, 4 and 5) for 30 seconds.
3)
The unbalancing of the panic zone (Terminals 27 and 28) causes
:
- Slow flashing of the ”
PANIC
” LED on the panel. The LEDs remain active until the next
arming of the panel to indicate “Alarm memory”.
- The activation of the panic alarm relay (Terminals 5, 6 and 7) for 10 seconds.
- The activation of the indoor and outdoor siren alarm relays (Terminals 9 to 17) for the
time they have been programmed.
4)
Low battery level (load under 10.5 V) causes
:
- Slow flashing of the “
LOW B.
” LED on the panel. The LED remain active until the next
arming of the panel to indicate “Alarm memory”.
5)
Opening of L1
L4 when functioning in N.C. or the violation of the zones (both not
excluded) will cause
:
- The lighting of the LED on the panel corresponding to the triggered zone only for the
time that the zone remains open or unbalanced.
