INGLE OR DUAL FIRE ALARM
(PDS
4)
Normally we work in dual fire zone mode. In some cases, a single mode state
can be useful. In dual mode, the extinguisher(s) are released after an alarm
condition is detected in both fire zones. In single mode, the extinguisher(s)
are released when one fire zone is in alarm.
PDS 4 OFF = automatic extinguishment activation with 2 fire zones in alarm.
PDS 4 ON = automatic extinguishing activation with 1 fire zone in alarm.

after the second fire alarm.
PDS 5 OFF = VFC relay active with 2
nd

PDS 5 ON = VFC relay active with 1
st
fire alarm.

XTINGUISHING DELAY TIMER
(PDS
6-7-8)
Extinguishing delay is only useful in normally occupied spaces. For the delay timer settings, there are
3 PDS, which can be set between 0 and 35 seconds, with steps of 5 seconds. The count-down timer is
used to wait a certain amount of time before extinguisher is activated. This timer can be set with the
use of the timer PDS 6,7 and 8.
