Connection of automatic and manual smoke detectors / BMZ
Instead of smoke detectors a connection module
(external closer contact) for EMERGENCY-OPEN from an
external fi re alarm system (FAS) may be connected to
terminal 1 / 22.
Only connect when disconnected from the mains power
supply! Switch off power supply and secure against
reconnection!
!
!
Cable installation must be in compliance with applica-
ble legal requirements. The terminal cross section for
connecting the detectors is maximum 1,5 mm², mini-
mum 0,5 mm².
The fi re detector connection is closed-circuit monitored
for line failures. Therefore, both the last smoke detector
and the last breakglass unit in the line must be provided
with a 10 k
resistor (RE) (see schematic diagram). If
the fi re alarm line is not used, mount the 10 k
resistor
on terminal 1 / 22. Otherwise, the yellow indicator „
S
“
signals a fault
