If using non-polarised sounders or bells, it is
necessary to install a 1N4007 diode to avoid the
effect of the reverse current.
4.2.1. Sounder timer
On the bottom left part of the MAIN BOARD there is
a double line with pins to configure the time delay
of the sounders. This time delay is configured by
placing the jumper in the corresponding position
of the desired timer (between 0 and 10 minutes).
4.3. Wiring of 24 VDC auxiliary output
CCD-020/040 control panels have 1 24 VDC
auxiliary output that is used to supply power to
the devices that require this power. Its maximum
current is 450 mA and it is protected by a fuse. Do
not use this output to supply power to devices with
excessive power consumption when on standby.
This output is not resettable.
4.4. Wiring of voltage-free relay output
CCD-020/040 control panels have a fault
relay and an alarm relay. These relays, with a
maximum current of 2 A, switch when the control
panel detects an alarm or fault. The fault relay is
energised and, if there is a loss of power, it will
signal the respective fault.
NO TE:
If using the contacts to
supply power to inductive loads, use
a protection diode to avoid damaging
the contacts.
