As the break glass units are monitored, the
connection of the break glass units depends
therefore of the number of smoke zones.
- 1 smoke zone: connect to break glass unit
bus 1. It is optional if they are connected in
a ring.
- 2 smoke zones: connect to break glass
unit bus 1 respectively to break glass unit
bus 2. It is optional if they are connected in
a ring.
- 3 or more smoke zones: break glass units
are always to be connected in a ring
Break glass units connected in a ring bus are
not as sensitive to errors on the cables, as
units which are not connected in a ring bus.
Smoke detectors and keypads can also be
connected on the break glass unit type WSK
501 / 502.
Per panel up to 10 break glass units can be
connected.
But only 2 of these 10 (one per line) can be a
type WSK 501 / 502 to which keypads or
smoke detectors can be connected. The
remaining break glass units must be type
WSK 503 / 504.
