Extinguishing Control Computer 8010 – 19-Inch
FB 798955.GB0 / 09.07 59
7.5.3 Relay outputs, 10 and 11
Free programmable, dry contact relays for low voltages.
The two relays 10 and 11 can be configured for the emergency operation via the appropriate jumpers. During
emergency operation, the corresponding relay mode is permanently assigned to the two relays. In a CPU-
failure-mode of the system these relays are activated.
