Optional Functions Not Approved to EN54 Pt 2 & 4
Italian Mode: (option not required by EN54 Pt 2)
This mode can be programmed at access level 3. This relates to points 12.2(a) and 12.2(b) of the Internal
Italian Ministerial Decree 9th April 1994 which states that in the event of a fire detection from 2 or more
detectors or from an MCP there should be a 2 minute delay before output activation otherwise in the
event of a fire detection from any one detector there should be a 5 minute delay before output activation,
provided that the fire event is not acknowledged. These delays apply to siren activation as well as the
shutting down/activation of other external equipment and additionally the legislation states that these
delays should be adjustable depending on the type of activity being carried out within the building.
For example, if there was a fire detected from a single detector then we should start a 5-minute
(adjustable) delay (T2). If however a fire is detected from a second detector or a call-point the delay
should automatically revert to 2 minutes (adjustable) (T1). In this scenario the value of (T1) is critical. To
keep things simple, let's assume that we set T1 = 2 minutes and T2 = 5 minutes.
Swedish Mode (option not required by EN54 Pt 2)
This mode is programmed at access level 3. One of the Swedish requirements is that access level 2 and
3 is only avalailabe by the access of the keyswitch. The key switch is wired to the class change input.
Commission per Loop (option not required by EN54 Pt 2)
This mode is programmed at access level 3. This allows the commissioning engineer to auto learn one
loop at the time
Alarm Verification (option not required by EN54 Pt 2)
This mode is programmed at access level 3.This has the flexibility to delay the activation of detectors by
30 seconds. In the event of an alarm from a detector, the led of the detector will be illuminated and no
alarm will be displayed on the panel. The detectors are checked continuously for 30 seconds. If after this
time, the detector is still in alarm, the output will be activated otherwise the detector will be reset.
Timer T1/T2 (option not required by EN54 Pt 2)
This mode is set on at access level 3 and is a commonly used by eastern european countries.
In the event of a fire the timer T1 can be set from 0 to 3 min where the alarm will be displayed on the
panel and no output activation, if during this time the alarm is acknowledged then timer T2 can be set
from 0-10 min where the alarm can be investigated and alarm reset. However if timer T1 and T2 time out
during alarm activation, the outputs will be activated.
Timer T1/T2 with callpoint Override (option not required by EN54 Pt 2)
This is similar to the above except a callpoint alarm will activate the output instantly
