Technical Address / Presentation Number
7.1
Technical Address for COM Loop Units
The technical address "NNN" is used when programming any unit connected to the COM
loop. The addressing tool 4414 / 4414E is used to write the address in a loop unit.
Technical address is also used to identify which unit has generated a fault.
•
The addresses don't have to be in sequence.
•
The connections on the COM loop don't have to be in sequence.
•
The technical address can be set to 001 – 255.
•
With the programming tool 4414E, the units can also be set to 000 (factory setting).
If the auto-addressing function should be used, the units on the loop must have technical
address 000. See the Technical Manual for the system.
A brand-new detector is factory set to COM loop (technical) address 000. Connected on
the COM loop, the detector LEDs will start blinking every second, indicating that an
address (001 - 255) has to be set before the detector will work.

Presentation Number
For each fire alarm point / input / zone, a presentation number NNN-NN has to be
programmed. The presentation number is shown in the FDCIE display and the external
display units, to identify the point / zone activating fire alarm.
It is also used to disable / re-enable fire alarm points / zones and as a trigger conditions in
the control expressions to activate programmable outputs.
Together with the presentation number, a user definable 40 characters text message
(alarm text) can be displayed (if programmed).
NNN
01-99
Zone number
NN
00-99
01 – 99 = The address within the zone.
00 = Only the zone number will be displayed,
e.g. used for conventional zone line inputs.
