Relay Outputs - Honeywell Esser 2 Series Operation And Installation Instruction

Extinguishing Control Computer 8010 - Series 2

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
Operating mode
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
Relay 10
Relay 11
Contact load
Operating mode
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!
