Enable Access Level 2; Enable/Disable Zone; Reset Of Panel - SD3 ALPHA 2 Operating & Installation Manual

3-2 SILENCE BUZZER AND/OR ALARM/FAULT OUTPUTS
In case of pre alarm, alarm or fault, ALPHA 2 turns the relative Leds and the buzzer
on. The acoustic signal can be deactivated without necessity of advanced access
level by pressing for a moment SILENCE BUZZER key.
At access level 2 and in case of alarm or fault, the key allows deactivation of relative
outputs.
This action is signalled by ignition of yellow led relative to this key and its effect lasts
until reset or until a new alarm/fault state occurs.
It is possible anyway to set the panel for an automatic deactivation of buzzer after
10min (see par.4-5)
NOTA: Automatic deactivation of buzzer is not applied for CPU Fault, for this
fault you need to reset the panel manually.

3-3 ENABLE ACCESS LEVEL 2

All the command available on ALPHA 2, except from SILENCE BUZZER and manual
activation of sounders line (in phase of delayed activation of sounders line), are
operative only after activating access level 2.
This access level, anticipated for specific users, is signalled by green led and is
activated by pressing an access code like detailed next:
a) Press and maintain key SILENCE BUZZER. This operation changes the nature of
the keys DISABLE of zone and become the following setting keys: Zone 1 = Key 1,
Zone 2 = Key 2.
b) Press sequence Key 1 and Key 2 (code access level 2)
c) Release the key SILENCE BUZZER.
If the operation has been executed correctly, green led level 2 will be ignited. This
access level 2 remains active for 30s since no key has been pressed during this time.
Access level 2 can be optionally activated by the means of mechanical key to be
inserted in the panel as well (see par.7-1).

3-4 ENABLE/DISABLE ZONE

Every single zone can be disabled or enabled by following this procedure:
a) Activate access level 2
b) Press key ON/OFF relative to the zone you want to disable/enable; if the
corresponding led goes yellow on it means that the zone is disabled and if the led is
off it means the zone is enabled (pressing the ON/OFF key switches alternatively the
zone ENABLE – DISABLE)
The deactivation of the zone remains permanent until it is manually activated again.
Disabled zones are considered non operative by ALPHA 2, therefore all alarm or fault
signalisations relative to disabled zones are ignored. Disabled zone remains able to
analyse the state of its line and keeps on indicating through led the eventual alarms
or faults kept in memory.
