17.3.1 Relay outputs
The power supply unit and relay board of the Extinguishing Control Computer provides 13 relay outputs for
switching and control functions. Status functions such as faults, deactivations, common fire or others of the
possible switching conditions can be assigned to the relays, whereby an OR logic operation of the individual
functions can also be programmed. All relay outputs are protected with separate melting fuses. The activation
time and the duration of each relay is programmable with the programming software.
Relays 1 to 8
Programmable relays for low voltages.
The relay mode can be configured via a jumper to >positive switching/monitoring< or >dry contact<.
Contact rating
: Changeover contacts, max. 30 V DC / 2 A
Operating mode
: Dry contact or positive switching / monitoring
Relays 9, 10 and 11
Programmable relays for low voltages.
The two relays no. 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.
Relay 9
: Without CPU-failure-mode capability
Relay 10
: Emergency operation fire (jumper J7)
Relay 11
: Emergency operation trouble (jumper J 5)
Contact load
: Changeover contact, max. 30 V DC / 2 A
Operating mode
: dry contact
The relays no. 1 to 11 must not be connected to high voltages even in the dry contact mode.
Switching an alternating voltage with this relay is
not
permissible!
