Beam Pair
Zones with this attribute cause an alarm only if two or more zones that are in the same
ward and have the Beam Pair attribute trigger within the time specified by the Beam Pair
timer (page 64). This attribute is normally used only for areas protected by an array of
infra-red beams, with each beam connected to a separate zone. Zones that have the Beam
Pair attribute should be the same type (normally Normal Alm or Perimeter).
Monitored
When triggered, a zone with this attribute activates outputs that follow the Monitored O/P
On (page 48) or Monitor (page 55) event.
Non Latching
Select this attribute for a zone of type Keyswitch (page 24), Shunt Key (page 24) or
Security (page 27) if a non-latching switch is used (i.e. a switch where the contacts do not
stay open after the key is operated).
Supervision
This attribute is for use with radio zones. If you wish to enable supervision for a radio zone
then you must set both the supervision warning timer, (option 1-5-2 27, see page 66).
and the supervision failure time (option 1-5-2 28, see page 66) to a figure greater
than 0.
YES – The control unit monitors this zone for supervision (default).
NO – The control unit ignores all supervision problems with this zone.
Note: By default the supervision attribute is set to YES for all zones, including the hardwired
zones. The control unit uses supervision monitoring on radio zones only, not on
hardwired zones.
Activity
This attribute works together with Downloader to aid remote monitoring of individual
zones. When enabled, the control unit sets an internal flag if the zone has been activated
at any time within the last seven unsetting periods. Downloader can display the state of
this flag and a remote engineer can use this information to judge the health of the
detector for that zone. An installer on-site can also view the state of this flag by means of
“View Zones” option 2-1. The display shows an “A” if the zone has been active within
the last seven unset periods.
YES – The control unit monitors this zone for activity.
NO – The control does not monitor this zone for activity (default).
Step 4 – Select Zone's Wards
Each zone can be assigned to one or more wards.
If the Ward configuration option (page 84) is set to ON, Zones assigned to more than one ward
will only be armed when all the wards they are in are set (by default this option is set to OFF).
