Fire Safety

Line card
Card for connecting peripheral devices. The card can be a plug-in card or it can be integrated into the
periphery board.
Local alarming
Local alarming equipment (e.g. acoustic or optical) is actuated in order to call up intervention personnel and
to alert people of a possible fire hazard.
Logical channel
Depiction of a logical device function in the detection or control tree. The logical channel is always the
bottom level in the structure tree.
Loop
Detector line topology which runs from the fire control panel via the fire detectors and back to improve
operational reliability. This type of wiring allows all detectors to communicate with the control panel even in
the event of an open line or short-circuit.
Management station
A superordinate system for monitoring and operating safety-related sites and buildings, e.g., fire, intrusion,
access, heating, ventilation.
Manned
Switching status of the alarm organization, if operating personnel are present and can intervene should an
event arise (alarm, fault).
Minor incident
Alarm situation which the operating personnel can handle themselves and does not, therefore, trigger global
alarming.
Multi-detector dependency
When using multi-detector dependency, the danger levels of several detectors are included in the alarm
decision. Measures such as alarming or closing the fire doors are only initiated when the defined
dependencies occur (e.g., two detectors detect danger level 3).
Network tree
Figure of the network in a fire detection installation.
Normal operation
The fire detection installation is supplied with mains voltage.
Parameter set
Defined detector behavior, e.g. in terms of sensitivity, resistance to deceptive phenomena, response time.
Detectors can be operated with different parameter sets.
Physical channel
Depiction of a device's physical function in the hardware tree. The physical channel is always the bottom
level in the hardware tree.
PMI
The arrangement of operating and display elements on a fire control panel or on a fire terminal. Includes the
LEDs, buttons, the display, and the operation options such as the key switch, fire brigade control and
display (FBA), and the EVAC NL Person Machine Interface.
