11.1
A
COUSTIC ALARM
The NCP has an internal attention signal. Malfunctions are standard signalized with a continuous tone
signal, alarms with a pulsating tone signal. Deviating tone signaling takes place with extinguishing
activation and operation of the hold (extinguishing delay) function. The voltage of the monitored
output to drive an additional sounder/beacon is controlled by the NCP and is independent of the main
power supply voltage level.
11.2
E
XTINGUISHANT RELEASE OUTPUT
The NMS is equipped with two activation techniques for the activation of fire extinguishing systems.
The selection can be made using PDS 3. By default, the NCP is programmed for the activation of
electrical igniters intended for aerosol fire extinguisher generators, with PDS 3 in the OFF position.
The activation of aerosol fire extinguisher units is actuated by means of a current pulse of 1.3A for
50ms. When PDS 3 is set to the ON position, the NMS is suitable for activating an extinguishing system
that makes use of a solenoid as actuator of the extinguishing installation. The activation voltage is
then 24V DC with a maximum of 1A.
IMPORTANT
For the default current pulse activation method (PDS 3 OFF) the NMS supply voltage, meant for electrically
activatable aerosol fire extinguisher units, is 8V to 28V DC. For the voltage-controlled activation (PDS 3 ON),
the NCP supply voltage, meant for an extinguishing system that uses a solenoid actuator, is 24VDC.
