of each standard -relay outputs-. Module lines can be programmed in 1, 2 or 4 detection groups following the Spanish,
German-Swiss and Italian Standards, and 1 or 2 groups following the Portuguese-International, French and Flemish
Standard.

DETECTORS INSTALLATION

To carry out the detectors installation use shield cable 4 wires -2 x 1.5 mm
cable communications-, bearing in mind that the max. length between Control Unit and the last detector installed -or
Interface- will be of up to 1000 m for toxic gases.
For reasons regarding consumption and in order to avoid drops in the installation voltage when using EXP detectors -
explosive gases - it is necessary the installation of an independent power supply per module line. Moreover, the supply
cable section must be increased up to 2,5 mm
DETECTORS 2 x 1.5 mm
Toxic gases 2 x 0,25 mm
DETECTORS 2 x 2.5 mm
Explosive gases 2 x 0,25 mm
* For longer lengths, consider the using of auxiliary power supplies.
** Depending on the applicable Standard
NOTE: Explosive detectors with plastic housing are not designed to be installed in environment requiring EEX grade
protection.

LED CODES IN THE DETECTORS

Blinking when the detector is in idle mode:
• Operating OK.
Fast Blinking:
• Detector not initialised.
• Detector not recognised by the Module Line.
• The programmed detector number coincides with another detector´s number.
Permanently lit up:
• EURODETECTOR CO: It indicates that the detected CO concentration is equal to or above 50 ppm.
• EXP DETECTOR: It indicates that the gas concentration is equal to or above 20% L.E.L.

SPECIAL CONSIDERATIONS FOR Cl

In order to shorter these sensors stabilization time, the detectors include a battery to permanently feed the circuit.
Before connecting these detectors to the Control Unit, follow next indications:
1. Remove the connector incorporated to the battery.
