5.1.2 Opening and closing the housing cover when the power
supply is switched on
When the housing cover is open, the mini USB connection and the internal
indicators are accessible.
Damage to electronic components in the aspirating smoke detector
● When working on the open aspirating smoke detector, use anti-static floor
mats and anti-static work surfaces.
●
Ground yourself immediately before opening the housing, e.g. by touching a
ground point or wearing an anti-static belt.
Accidental triggering of an alarm
Triggering a false alarm
● When the housing cover is opened, the buzzer sounds. The relay outputs
remain active and the 4…20 mA analog output has been switched to fault
(0.5 mA).
● If the button is pressed, the buzzer switches off and the relay
outputs are deactivated. The 4…20 mA analog output remains on fault.
●
Closing the housing cover automatically reactivates the relay outputs and the
4…20 mA analog output switches to normal operation.
