Detection Block Connection - Detnov CCD-103 Mode D'emploi

The extinguishing panel connections are divided into two blocks.
Conventional detection block, with the following inputs and outputs:
- Zone Inputs 1,2 and 3.
- Alarm and Fault relay outputs.
- General alarm sounder output.
- 24 V aux. output.
- Exterior input.
- Ventilation relay output.
Extinction block, with the following inputs and outputs:
- Extinction bottle solenoid output.
- Warning sign "Don't enter extinction active" output.
- State 1 and 2 sounder outputs.
- Triggering, stop and hold MCP inputs.
- Door surveillance and 2 bottle surveillance inputs.

4.1- Detection Block Connection

4.1.1- Detectors Connection
In the factory default configuration, the extinguishing panel has 3 zones. Zones 1 and
2 work as crossed zones in order to activate the automatic extinction process. Zone 3
is an independent zone for adjacent zones.
The extinguishant fire panel is compatible with the conventional range detectors and it
will not work properly with another detectors
As indicated in the drawing above, the positive connects to contact number 1 both in
the input and output. The negative connects to the line input at contact 4 and leaves
through contact 3 to the following detector. At the end of the line you must place a
4K7 end-of-line. Remember that the maximum number of detectors per zone is 32
detectors or 32 MCP.
If you are not going to use all the zones, it is necessary to connect the end-of-line
resistor (4.7kOhm) at the terminals of the not used zone in order to avoid a fault signal
from the system.
