Zone Types
Zones will report differently depending on the Zone type assigned. For example, a zone set as an Alarm type zone will report an
input going open as a full alarm when the System is Full Set.The behaviour of many zones is based on that of the most common
zone type “Alarm”, so it is advisable to use this type as a reference. For all zone types, a discon (disconnected) or tamper alarm
activation is reported in the same fashion as an Alarm type zone, as well as generating a technical fault.
Note that zone behaviour as detailed below can be radically altered by assigning Zone Attributes, so it is therefore essential to be
familiar with the consequences of such actions. See “Zone Attributes” section for a full explanation of all Zone attributes.
Area -1 to
Area -30
Available only when the number of areas is greater than 0. Area zones are instant Alarm zones which are
active when the relevant area is set/armed. When activated, these trip the intruder alarm output (Out-
put 1), the External and Internal bell outputs (2 and 7), as well as the relevant Area Alarm, Bell and
Strobe outputs. All attributes are assignable to Area zones.
Note: If one area is in Alarm and a second Area goes into alarm, the relevant Alarm output will trigger
for the second Area, but the Area Bell and Strobe outputs will not trigger unless the Bell and Strobe from
the first area have switched off, and the “Retrigger” variable is set to YES.
FTC
This zone type is used in conjunction with the FTC relay on the DM1200. The FTC zone is a normally
closed zone type which is wired in series with the FTC relay. In the event that the DM1200 cannot com-
municate with the ARC, the FTC relay trips causing the FTC zone type to open.
Note If the “Service Reset” variable is set to 1,an FTC zone type generates a call service
and an engineer will be required to clear the alert.
Common
Available only when the number of areas is greater than 0. The Common zone is active when the Com-
mon Area is set/armed – that is, when all other areas are set/armed and the “Common Area” variable is
set to YES. When activated, a Common Zone type will trip the intruder alarm output (Output 1), the
External and Internal bell outputs (2 and 7), as well as the Common Area Alarm, Bell and Strobe out-
puts. All attributes are assignable to Common zones.
Part
Available only when the number of Areas equals 0. Part zones are instant Alarm zones which are active
in Part Set, Half Set and Full Set modes. When activated, a Part Zone type will trip the intruder alarm
output (Output 1), the External and Internal bell outputs (2 and 7), as well as the Common Area Alarm,
Bell and Strobe outputs.
The Part zone type can be applied to perimeter zones of a premises so that when the Part Set mode is
chosen, the perimeter of the premises is protected while free movement is allowed through the exit and
access area and inside the building (i.e. the exit door is configured as an Alarm zone type with the Exit
attribute, and any sensors in the Access area are also configured as Alarm zone types with Access
attributes). Only limited attributes can be assigned to Part Zones, namely Inhibit, Exit, Fire-X and Double
Knock. If other attributes are required use an Alarm zone type instead.
Half
Available only when the number of Areas equals 0. Half zones are instant Alarm zones which are active
in Half Set and Full Set modes. When activated, a Half Zone type will trip the intruder alarm output
(Output 1), the External and Internal bell outputs (2 and 7), as well as the Common Area Alarm, Bell and
Strobe outputs.
The Half zone type can be applied to perimeter zones of a premises so that when the Half Set mode is
chosen, the perimeter of the premises (including all exits) is protected, but free movement is allowed
inside the building, i.e. Late working operation. Only limited attributes can be assigned to Half Zones,
namely Inhibit, Exit, Fire-X and Double Knock. If other attributes are required use an Alarm zone type
instead.
