FDR-3G
Type of activation BST1
IMPORTANT: Danger of electric shock! Parallel circuits, i.e. a smoke detector on multiple slave devices are not allowed!
Switch off the power supply before working on any electrical equipment.
Allow only qualified electricians to work on the electrical system.
Actuator power supply via fitted communication unit: DC 24 V
NOTES:
• Left: Connection scheme for fitted communication and supply unit BC24-G2 (THC).
• Right: Example connection scheme for smoke detector ORS 142 K from Hekatron - not part of the delivery.
LEDs status indication (BST1)
LED colour| LED state | Status
Green | ON | Damper open
Green | Blinks | Damper is opening
Yellow | ON | Damper closed
Yellow | Blinks | Damper is closing
White | Blinks | SLC-communication ok – control command „close damper“
White | Flashes | SLC-communication ok – control command „open damper“
Red | ON | Safety element triggered (at X4)
Red | Blinks | self-test active; error: communication loss; error: actuator not connected; error: thermoelectric tripping
device of actuator triggered; runtime monitoring error; mechanical error triggered
