Break glass unit
Up to 10 break glass units type WSK 50x can be connected to the WCA 3SS, but
only 1 WSK 501 / 502 per line, meaning max 2 WSK 501 / 502 per panel.
Smoke detectors and ventilation keypads can only be connected to the break
glass units type WSK 501 / 502.
Up to 10 smoke detectors can be connected to each WSK 501 / 502, and 10
smoke detectors can be connected to the smoke detector input on the main
control card, which give a total maximum of 30 smoke detectors.
There is no limit on the number of ventilation keypads connected to the WSK 501
/ 502.
Smoke detectors and ventilation keypads cannot be connected to WSK 503 /
504.
