System overview
Spur tolerant soft addressing
The control panel utilises intelligent soft addressing technology to greatly simplify the
installation and commissioning processes .
Once the system has been installed and the autolearn menu selected, the control
panel will automatically scan the detection loops and allocate each device with
an address number corresponding with its position on the loop, this avoids the
traditional need for manual addressing of the system devices which is time
consuming and provides a potential for error .
A major innovation is the ability to incorporate spurs of analogue devices which are
fed from the main loop by utilising a spur isolator . Whenever the panel detects a
spur, it breaks from allocating address numbers to the loop wired devices, allocates
address numbers to each of the devices on the spur in sequence and then continues
to address the devices on the main loop .
Every analogue device incorporates an integral short circuit isolator ensuring
maximum system integrity . A single short circuit will not disable any loop-mounted
devices, the isolators in the devices each side of the short circuit will operate and the
control panel will drive communication from both ends of the loop .
The spur isolator also incorporates a short circuit isolator such that in the event of
a short circuit on the spur, the integrity of the main loop will not be compromised .
Please refer to local standards e .g . BS5839 Pt1:2017 for details of the maximum
allowable are to be covered by a single spur .
Simple future expansion
The system is designed to ensure simplicity of future expansion . If an additional
device is added after the system has been programmed, the control panel will
allocate the next available address, it will not alter any of the existing address
numbers allocation thus enabling simple updating of as fitted drawings etc .
Similarly if a device is removed, the relevant address is saved as a spare address for
future use, the addresses of the remaining devices are not altered .
