Imax = 64mA when 30 break glass units and 100 smoke detectors.
As the break glass units are monitored,
the connection of the break glass units
depends therefore of the number of
smoke zones.
The break glass units can always be
connected in a ring but must, as a
minimum:
- when 1 smoke zone - connect to break
glass unit bus 1
- when 2 smoke zones - connect to
break glass unit bus 1 respectively to
break glass unit bus 2
- when 3 or more smoke zones -
connect in ring
Smoke detectors and keypads are
connected on the break glass unit type
WSK 501/502.
Per 20A section up to 30 break glass
units can be connected.
On max 10 of these 30 break glass units
smoke detectors type WSA 300 can be
connected - and max 10 smoke
detectors per break glass unit.
This gives a total of 100 smoke detectors
per 20A section.
