An explanation of the SIA codes used with the SIA-HS protocol can be found in appendix C at page 84.
When the zone is programmed as a type 6
key
, this input will function as a keyswitch input. Every time this
input is activated, the sections programmed to it are activated or deactivated, depending on the state the
sections are in.
All zones of type 6 are by default programmed as pulse switches. When the input changes from opened to
closed, this is recognized as a pulse and the programmed sections are armed or disarmed.
In screen 8 it is possible to change the functionality of the keyswitch input from pulse to latch. In case of the
latch mode, the zone will disarm the programmed sections when the zone is closed, and arm the sections
when the zone is open. When the Eol principal is used, the functionality stays the same. When the zone is
switched to 11k8, the sections are armed, and when the zone is switched to 1k8, the sections are disarmed. If
you wish the functionality to be the other way around, you can program the zone as normally open.
Attention:
When the keyswitch is used with the EOL principal, tampering the keyswitch will also be
noticed. The keyswitch will not function if the last EOL reading was tamper. Only when the last EOL
reading was a valid reading (either 1k8 or 11k8), the keyswitch will be able to arm or disarm the control
panel.
When a Keyswitch zone is coupled to more than one section, all these sections will be armed or disarmed
simultaneously.
When, during arming with the keyswitch, there are any direct zones still open, the control panel will try to
bypass (block) these zones automatically. To prevent unintentional bypass, all zones are by default
programmed so that they are not allowed to be bypassed. (see “Bypass” at the next page) When the SIA or
SIA-HS protocol is used, every zone being bypassed is reported to the monitoring station.
Attention:
When the control panel cannot bypass the open direct zone, because this zone is not allowed to
be bypassed, the control panel will not arm any of the sections programmed to the keyswitch! Therefore
when a keyswitch is used, we advise to connect an OK LED for visual confirmation.
When the zone is programmed as a type 7
direct dialler control
, the AlphaVision NG control panel will act
like a dialler and send out a report when the input is activated, no matter the state of the AlphaVision NG.
When the input returns to the idle state, a restore report will be send out. With this type of zone available,
the AlphaVision NG control panel can be used as a dialler with up to 96 zones, with all zones having their
own programmable zone description. When a type 7 zone is activated, it is not shown in the LCD display,
but it is saved in the historical overview.
When a zone is programmed as a type 0
not active
zone, it is completely ignored by the control panel and
does not need to be shut off with a resistor. This type of zone is used to define unused inputs. When a zone is
programmed as a type 0 zone, you
must
fill in an “x” at the bypass column. In this case a user can bypass
the zone.
