4. 1 Check the correct functioning of the detector with testing gas every 6 months 1 2 Recalibrate FIDEGAS S/3 detector every 2 years during its working life (at manufacturer´s factory) Each filter/sensor has its own electronic circuits Do not swap sensors or circuits. FIDEGAS S/3. Exproof detectors maintenance

5. Release the cables from the connector marked with 1, 2, 3, & Earth connection. • Releasing the self-blocking take out the whole set (cable + connector/s). • 2. Release sensor´s connector. • 3. Unscrew the filter/sensor. • Do not twist the flat cable, neither hook it with other elements. • 4. Electronic circuit can be dissassembled after releasing 2 subjection screws. FIDEGAS S/3. Exproof detectors maintenance Dissassemble and replacement of FIDEGAS S/3 detector Each filter/sensor has its own electronic circuit Do not swap sensors or circuits.

7. 2. Control unit´s bag includes the following replacements: 2 1Afuses Thermal retractable tubeto isolate the detector-panel shield connection cable avoiding short-circuits Conectors It allows the correct functioning of the panel when one or more are not connected (or if they has been disconnected for revisions). Screw M-4. Electronic circuit FIDEGAS CA Quick installation guide 1. Mount on the wall the control unit (door to be opened from left to right). 3. Control unit – detector connection Fuse 1A. Protect the detectors. All fault LEDs lightining up mean blowed fuse Connect: control unit-detector Isolate the shield using the thermal retractable tube and connect it to EARTH in the proper connector. Place the connector in those non used connectors

8. Between C & NO (ALARM) Between C & NC (GAS CUT) PREALARM: This output its timed to activate the extraction during 2 minutes. IT SHOULD NOT ACTIVATE ALARMS 12V CC Outputs Do the connection between C & NC or C & NO, being sure that the devices connected (electrovalve, contactor, siren, etc.) work at 2V and total consumption does not exceed the C fuse value of 0,5A. FIDEGAS CA2. Conector 230V AC Dry contact (close contact and no powered). Between C & NC (ALARM) Between C & NO (GAS CUT) Example of 12V output connection to an electrovalve FIDEGAS CA2.Conector 12V DC FIDEGAS CA Quick installation guide 230V CAOutputs Do the connection between C & NC or C & NO, being sure that the devices connected (electrovalve, contactor, siren, etc.) work at 230V and total consumption does not exceed the B fuse value of 2A. CONSIDERATIONS: When connecting 230V -or after a main fault- wait for 30 s before REARMING the system.Pay attention to the fuses capacity (mentioned in the manual)When all fault LEDs will be lightining up, check the state of the fuse ( D - E )

9. Testing bottle concentration is not suitable for calibration neither precision test. Ii is only recommended to check the detectors correct functioning. FIDEGAS CA Quick installation guide FIDEGAS S/3 DETECTORS testing: Put the cap on the sensor head 1 Introduce cannula In the cap´s hole 2 Release gas for 2 s. to activate alarm Wait 3 s before releasing more gas as required gas concentration to activate the ALARM keeps 2 m in the mask aprox.. 3
