Building Technologies
Fire Safety
Alarming is controlled at 'Area' level. During alarming the ↑ alarming equipment is
activated, e.g., ↑ alarm devices and remote transmission devices.
↑ Alarm devices
For ↑ local and ↑ global alarming, acoustic alarm devices, beacons, digital outputs,
etc., can be used. The tone of the alarm devices can be configured differently for
local and global alarming (the alarm devices must be suitable for this).
Remote transmission
The alarm message is transmitted to an intervention station. In the case of local
alarming, this is usually the company fire brigade and for global alarm usually the
state fire brigade. A remote transmission device must be used to transmit alarm
messages via the public telephone network.
