4.1.10 Creating a Common Area
In certain situations, a ‘common’ area may be needed. A common area is an area that only
sets if other specific areas are set. For example, a reception in a building will only need to be
set if the offices and warehouse are set. If the office is set, but the warehouse is not, then the
reception would still need to be inactive so people would be able to leave the premises. An
example of how to set this up is as follows:
Office:
Inputs 1, 2, 3 and 4.
Warehouse:
Inputs 5, 6 and 7.
Reception:
Input 8.
Therefore what we would need to do in the above situation is program the office in one area
(for example Area A) and program the warehouse in another area (for example in Area B). We
then need to make the Reception ‘common’ to these two areas (Partitions A and B), so we
need to select both areas A and B for this input (input 8). After selecting the partitions for each
input there is an option called “Input Area: Any/All”. For inputs 1, 2, 3, 4, 5, 6 and 7 we need
to make this attribute ‘any’, as they work independently to the area they are assigned to. For
input 8 (The common area), we need to make this attribute as ‘all’, therefore when partitions A
and B are both armed, the reception (input 8) will automatically set as well. In these
examples, the user codes could be allocated to individual areas A and B or to both areas.
However, the keypad controlling the common area MUST be programmed to be “IN” exactly
the same combination of areas as the common inputs – i.e. in “AB” in this example.
4.1.11 Input Attributes
Attribute
Response Modification
Chime
System loudspeaker(s) will ‘chime’ when an input triggered whilst the alarm
panel is unset. Note: The input concerned will not indicate on the display.
Single
System chimes once when the input is triggered.
Follow
System chimes until the input is cleared.
Omittable
Enables the input to be manually omitted during the Setting procedure.
Double
Knock
The input will only generate an alarm if triggered twice within a pre-set period,
or if the input remains in fault condition for that period.
Dual Trip
The input will only generate an alarm if this input, and another like -
programmed input with adjacent number, are in alarm condition at the same
time. Either input in alarm condition will prevent the system from Setting.
Normally
Open
Enables the system to respond correctly when detectors of ‘normally open’
configuration are wired to the system. Alternatively converts input types which
default to ‘normally open’ (e.g. PTS) to operate with normally closed devices.
Walk Test
If enabled, the input must be walk tested before the system can be set.
Monitor
Activity
Enables an input to generate an alarm if the input does not see any activity for
a period specified by the NAT (Non Activity Time) timer. (See change timers)
Special
Log
Forces a log entry when the input is opened or closed, even when an alarm
does not result. May be selected to apply when a system is set, when unset,
or always.
Confirm
Group
If one or more inputs are activated within the
same
confirm group, all
confirmed signals will be disabled. If confirm group is selected as ‘00’ the
inputs are not part of any group. If inputs are allocated to group 99 they will
generate an alarm that results in an intruder (unconfirmed) signal to an ARC
only. They will not under any circumstances generate a confirmed signal,
regardless of which group the input that activated the ‘unconfirmed’ alarm is
allocated to.
Any input may be programmed with any combination of these attributes, except where stated.
