Appendix B - General Guidelines

Labels
¨
Labels are given to identify location of areas on a site.
¨
A previous created label can be modified.
¨
for manual call points enter text MCP in the label description.
¨
a 32 character label can be given to a device, each Input/Output line, zone or sector
¨
A supervisory input channel label of an interface unit will be displayed at the
control panel when an interface input has operated.
Sectors
¨
There can be up to 16 Alarm or Plant sectors
¨
a sector is a collection of devices having a common action.
¨
a sector that is actioned ON will activate its alarm devices, such as interface outputs,
S-cube and Visual and audible part of an S-Quad.
¨
a sector signal can be Continuous (factory default for Class Change), 0.25 second
pulse (factory default for Alert), Nee-naw (factory default for Evacuate) or 0.5 second
pulse (factory default for Test)
¨
Alarm sectors operate automatically with 'Sound Alarms' and 'Silence Alarms'
buttons
¨
Plant sectors are independent of the 'Sound Alarms' button and are primarily used
with plant control equipment and can be silenced by pressing the 'Reset' button.
¨
A loop powered interface outputs can be assigned to a sector.
¨
Alarm sounders and interface outputs are restricted to one sector only.
¨
The fire plan on power up is known as 'one out all out'. This is when sector 1 has all
the sounder and output devices of the system. A fire event will activate evacuate on
all interface outputs and alarm sounders in the system.
¨
A sector can be assigned for activation by class change.
¨
It is advisable to build a fail safe mechanism when sectoring. If for any reason certain
sector assignment has been lost due to system power-down and subsequent NVM
recovery conflicts on system power up, the sounders will still operate in a fire
condition.
¨
the fail safe mechanism will involve leaving Sector 1 free from any device
assignment, as any devices that lose their sector assignment will default to Sector 1.

Day Mode delays
¨
a Day Mode delay can be:
•
switched ON / OFF manually at the panel
•
or preconfigured to operate ON, OFF or with CALENDAR
Zones
¨
A zone has a collection of trigger devices that are located in the same general area. It
may be used for one or all three of the following:
•
for illumination of zonal fire at the panel
•
for common disablement purposes
¨
a device may only be assigned to one zone.
¨
input/output lines of an interface can be assigned individually to zones.
¨
a zone is a collection of devices, sharing a common label
¨
zones default to normal operation and can be configured for coincidence operation
•
coincidence of 2 detector operation in a zone or
•
coincidence of 2 zone
¨
disabling a zone will disable the sensors within that zone
¨
all devices default to zone 1
"
The exceptions are devices that cannot be zoned, see page 36.
Fire relay
¨
The 'Fire relay' is not enabled (factory default) and can be enabled to operate with
zone fire. The relay is normally de-energised.
