2.- Get rid of the the outer cover and pull back the mesh (pic 2).

3.- Adjust the mesh to the inner part of the cable gland, helping yourself with a screwdriver (pic 3).

1.- Unscrew the cable gland. Pass the cable through the cable gland about 15 cm. (pic.1). Mark the cable and cut the outer cover.

4.- Introduce the washer to adjust the mesh inside the cable gland (pic 4). Fix the security circlip and adjust it against the washer helping yourself with a screwdriver (pic 5).

5.- Connect the cables in the wire clamp (pic 6).

6.- Assemble and fix the cable clamp with the right wrench in the correct order as indicated in pic. 7, 8 and 9.

7.- Once you have tighten the cable gland, connect the wire clamp and close the cover. Do not forget the allen security screw

Dissassemble and replacement of FIDEGAS S/3 detector

1. 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 .

1. Mount on the wall the control unit (door to be opened from left to right).

2. Control unit´s bag includes the following replacements: 2 1A fuses Thermal retractable tube to 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

3. Control unit – detector connection

Fuse 1A. Protect the detectors. All fault LEDs lightining up mean blowed fuse

Isolate the shield using the thermal retractable tube and connect it to EARTH in the proper connector.

Connect: control unit-detector

Place the connector in those non used connectors

FIDEGAS CA2. Conector 230V AC

PREALARM: This output its timed to activate the extraction during 2 minutes.IT SHOULD NOT ACTIVATE ALARMS

Between C & NO (ALARM)

Between C & NC (GAS CUT)

230V CA OutputsDo 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.

12V CC OutputsDo 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.

Example of 12V output connection to an electrovalve

FIDEGAS CA2. Conector 12V DC

Dry contact (close contact and no powered).

Between C & NC (ALARM)

Between C & NO (GAS CUT)

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 )
