Installation and maintenance
A fire extinguishing system is operated by a fire extinguishing control unit. These installations must comply with the EN-12094-1 standard and SVI regulations.
Operating a fire extinguishing installation
Automated fire detection installation
Below you see the actions the installation generates by means of an automated fire detection (dual detector, two group-dependent or aspiration):
1st ALARM (1st DETECTOR RECEIVES WARNING)
Optical & acoustic alarm (pulsing tone) goes off. This is also called a Slow-Whoop. Via the potential-free contacts (when implemented), a signal is sent to the alarm centre and possible air treatment systems are deactivated;
2nd ALARM (2nd DETECTOR RECEIVES WARNING)
Optical & acoustic alarm (continuous tone) goes off. This goes off inside as well as outside the area;
a delay of 30 seconds is effected, after which the fire extinguishing installation is activated;
Connected manual operation
The extinguishing installation can be manually activated by pressing the yellow button. After the installation has been activated, the acoustic and optical alarms are activated and a 30-second delay is effected, giving everyone enough time to leave the area.
Alarms that have been activated cannot be disarmed without proper procedures. They can only be disarmed by authorised people. These people will first check the area to determine that the danger has passed. When gas extinguishing systems are used, the area can only be entered by authorised people with respiratory devices and measuring equipment to measure the released extinguishing gas and oxygen level. Inside an area where a fire occurred (no matter how small), the presence of toxic substances and gases must always be taken into account. THIS MEANS THAT THESE AREAS MUST NEVER BE ACCESSED WITHOUT PROPER PRECAUTIONS!
To access an area safely and/or carry out activities in such an area (particularly when gas extinguishing installations are used), the door needs to be fitted with a key switch that can be used to disarm the automated operation of the extinguishing installation.
Electrical fire alarm installations

Furthermore, in compliance with NEN-2535, the extinguishing installation must be powered by at least two independent power sources. Both must be able to operate the entire installation independently from each other. Inside the meter cupboard, it must be clearly indicated which separate group(s) is/are allocated to the extinguishing installation.
With regard to the delivery of a fire extinguishing installation, the Logbook is an important element. This Logbook needs at least include the following information:
The operating instructions must be delivered and/or translated into the language of the user and include at least a set in the Dutch language. The same applies to all operating and detection equipment of the extinguishing installation.
Required maintenance for FirePro extinguishing systems:
The maintenance on conventional fire extinguishing systems often requires the deployment of technicians qualified in different areas, while the maintenance of FirePro extinguishing systems can be carried out in a much easier and less time-consuming way by specialist CATTAS personnel.
The inspection and filling of compressed gas cylinders is no longer necessary, just as there is no need to maintain a supply of often large and expensive spare parts for such installations.
Please note: all installation, maintenance, and replacement work with regard to empty units can only be carried out by authorised personnel of the supplier.
