2.3 Panel relays
Panel has four relays located on the power management board marked
AUX
,
FAULT
,
SUPPLY
and
OPER
.
The behavior of the operation (
OPER
), supply (
SUPPLY
) and fault (
FAULT
) relays is predefined and cannot
change. All relays are rated 30Vdc, 5A max. External fuses must be added based on the rated current of the
connected circuit.
Operation of each relay is described at the table below.
Table 3
– Panel relays
RELAY
DESCRIPTION
Operation
Relay state depends on system operation.
Supply
Relay state depends on the status of mains power supply.
Fault
Relay state changes if there is one or more faults.
Auxiliary
Operation of this relay is user configurable.
2.4 Inputs
The panel has four programmable inputs on the power management board marked as
IN1
,
IN2
,
IN3
and
IN4
on the PCB. Each input can be programmed to perform a specific action on all zones or a certain zone.
Activating an input can trigger one of these actions:
Table 4
– Input triggered actions
TRIGGERED ACTION
DESCRIPTION
FUNCTION TEST
Starts a function test on the points of the selected zone.
INHIBIT
Sets all points of the selected zone in
inhibit mode
.
RESET PANEL FAULTS
Resets the active faults on the panel.
2.5 Outputs
The panel has four outputs on the power management board marked as
24VP
,
24VM
,
OUT1
and
OUT2
on
the PCB. Two of them are voltage outputs (
24VP
and
24VM
) and the other two are programmable outputs
(
OUT1
and
OUT2
).
