Detection measures The main tasks of an automated fire protection system are to detect (an incipient
stage) fire, sound an acoustic alarm, notify the fire service and activate the pre-
programmed control functions. Such a system consists of a control unit with
peripheral input devices (such as manual call points and automatic fire detectors),
output devices (such as sounders and beacons) and output contacts to control
other systems (such as smoke control systems, HVAC systems, elevators,
automated extinguishing systems, etc.).
To minimize the danger to life and minimize business interruptions and loss of
data as well as any damage to property, it is important to detect a fire as early as
possible. Optimal product selection combined with the appropriate knowledge
make it possible to design a fire detection system capable of detecting a fire
extremely early and virtually eliminate any danger of false alarms.
Chapter 2 describes the measures needed to ensure that a fire is detected reliably
and at the earliest possible stage.
Alarm and evacuation
measures
When a fire breaks out prompt warning is essential and buildings must be
evacuated within minutes to protect people’s lives.
The purpose of a (acoustic) fire alarm is to warn people of the potential hazard.
In a basic installation the fire detection system must activate the installed alarm
devices and transmit the alarm signal to the fire department.
More sophisticated installations may include a dedicated voice alarm system,
which can be instrumental in preventing panic by providing clear information
about the danger and any required evacuation procedures through calm and
concise announcements.
In addition to the type of alarm and evacuation system provided, evacuation
plans, escape route identifications, emergency lighting systems and smoke
venting systems are essential to ensure a fast and safe evacuation of all persons.
To enable a safe evacuation, the emergency lighting must be turned on in all
relevant areas.
Air handling systems remove smoke from a building allowing the escape routes to
be kept clear of smoke which is essential to enable people to leave the building in
a quick and safe manner.
Chapter 3 describes the measures needed to alert staff and the intervention
forces, and how to ensure a fast and safe evacuation
