2.3. Extemal Release Extinguishing Input
The SFCP Rail has a separate input for an external release extinguishing button. The
extemal release extinguishing button has the same function as the dual release
extinguishing buttons (fire buttons) on the front of the panel. By pressing the extemal
release extinguishing button the fire extinguishing devices will be released. Depending on
the dip-switch (time) settings it is possible the release is delayed. The delayed can be set
from 0 to 30 seconds in steps of 5 seconds. The zone inputs are continuously scanned for
fire or fault detection.
The Input of the external release extinguishing Input is set to the following values:

RESISTANCE of less than 190 Ohm: FAULT

RESISTANCE of more than 190 Ohm and less than 1k2 Ohm: RELEASE

RESISTANCE of more than 10k Ohm and less than 12k Ohm: NORMAL

RESISTANCE of more than 12k Ohm: FAULT
The external release extinguishing Input needs a 10k Ohm resistor as End-Of-Line (EOL) resistor,
even when the input will not be used. This to prevent a detection fault on the input(s).
2.4. External Hold Input
The SFCP Rail has a separate input for an external hold-off button. The external hold-off button has
the same function as the internal hold-off button. When an alarm is active and this button is pressed,
the extinguisher enabling is delayed. When the button is released, the system will wait 5 seconds.
After these 5 seconds, the count-down timer will reset and start from the set delay time. The
monitored inputs are continuously scanned for fire or fault detection.
The Input of the external release extinguishing Input is set to the following values:

RESISTANCE of less than 190 Ohm: FAULT

RESISTANCE of more than 190 Ohm and less than 1k2 Ohm: HOLD-OFF

RESISTANCE of more than 10k Ohm and less than 12k Ohm: NORMAL

RESISTANCE of more than 12k Ohm: FAULT
The external hold-off input needs a 10k Ohm resistor as End-Of-Line (EOL) resistor, even when the
input will not be used. This to prevent a detection fault on the input(s).
If the external hold-off button is pressed during normal state (no fire / alarms), the SFCP Rail will
give on fault on the front. Which can be recognized by the blinking of the yellow detection fault
LED. The detection fault will lit up for 3 seconds and then flash five times, which indicates the
external hold-off button is pressed.
2.5. Direct Fire
When the timer settings are set to a delay (between 5
— 30 seconds), the direct fire dip-switch
gives the choice to override the delay in case of a fire event. If a fire alarm is detected by the SFCP
Rail and the count-down timer is started you can override the timer. By pressing the dual release
extinguishing buttons (fire buttons) on the front of the panel or the external release extinguishing
button (when commissioned) in the fire state you start the extinguishing releasing process.
Note: Make sure the fire-extinguisher is safe to release. Any delay on the extinguishing
release system will be override immediately, and start the fire-extinguisher!
