WARNING !
THE INSTALLATION OF THE DETECTOR DOESN’T EXEMPT FROM THE OBSERVANCE OF ALL RULES ABOUT THE CHARACTERISTICS, INSTALLATIONS AND THE USE OF THE GAS DEVICES, THE VENTILATION OF THE ROOMS AND THE EMISSIONS OF THE PRODUCTS OF THE COMBUSTION PRESCRIBED FROM UNI STANDARDS AND THE PROVISIONS OF THE LAW.

WIRING DIAGRAM

WARNING!
THE GAS DETECTOR MUST ONLY BE POWERED THROUGH THE POWER CORD CONNECTED TO THE DEVICE.

IF THE INSTALLATION ALSO INCLUDES A SOLENOID VALVE, THE ELECTRICAL SAFETY AND THE PROPER OPERATION OF THE DEVICE ARE GUARANTEED ONLY IF THE ELECTRICAL CONNECTION IS MADE WITH A FIXED WIRING THAT TAKES ADVANTAGE OF THE SPECIFIC OPENING IN THE PLASTIC BASE (SHOWN WITH THE ARROW IN FIG. 3) SO THAT THE IP PROTECTION DEGREE OF THE ASSEMBLY IS NOT AFFECTED.

SHOULD THE POWER SUPPLY CORD BE DAMAGED, THIS CAN ONLY BE REPLACED BY AN IDENTICAL ONE AVAILABLE FROM THE MANUFACTURER OR ITS TECHNICAL SUPPORT SERVICE.

OPERATION

The BEAGLE Plus –S (Fig. 1) is a flammable gas leakage domestic detector. When exposed to a gas concentration much lower than the danger level, the detector turns on a red light and a buzzer, then, after 5 seconds it, turns on a relay which can be used to stop the gas supply.
OPERATION

Note: The user might smell the presence of gas before the detector does; this happens because the distribution companies use to add odorizers to natural gas and LPG.

This sensation is extremely variable from person to person, and depends on the exposure time.

To test the correct operation of the detector, hold down for 5 seconds the button ’T’ (Test) on the frontal panel: the green, yellow and red LEDs will turn on; the buzzer will buzz and after 5 seconds the relay contact is activated.

The BEAGLE Plus –S is equipped with a delay line which avoids the intervention of the alarm system (in order for the gas sensor to heat up) whenever the device is turned on or even after a mains black-out, as soon as the power comes back. After that delay (about 30 seconds) the yellow LED turns off and the green LED remains on to show that the detector is powered.

The BEAGLE Plus –S features an auto-diagnostics system which verifies the sensor reliability. When the yellow indicator is turned on (sensor fail) the possible causes must be searched among the following:

sensor fail;
sensor disconnected;
detector malfunctioning.

INSTALLATION

This device is intended for wall mount only. To access to the internal terminals, remove the front panel by loosening the screw (Fig. 2).

The power supply of the unit is solely intended to be through the connected power cord.
If the installation also includes the connection of a load, it will be necessary to remove, with a screwdriver, the plastic part indicated by the arrow in Fig. 3, to pass the cables of the fixed wiring. Then make the wiring as proposed in diagram of Fig. 5 or 6.

Please note that the intervention delay is strictly dependent both on a correct positioning of the detector in the room and to the type of gas to be detected.
In case of ‘heavy’ gases (as for LPG) an installation in low places is advisable (about 30 cm from floor level), meanwhile for ’light’ gases like methane in high places (about 30 cm from ceiling level).
Please avoid to install this gas detector in any position i which its operational features could be compromised, such as the following:

in an enclosed space (e.g. in a cupboard or behind a curtain;
directly above a sink;
next to a door or window;
next to an extractor fan;
in an area where the temperature may drop below – 10°C or exceed + 40°C;
where dirt and dust may block the sensor;
in a damp or humid location.

Do not use the following substances in the device immediate adjacency:

alcohol, fuels
solvents and diluents
adhesives, silicones products and colours
cleaning detergents
perfumes
spray products in general

Clean the device only using a cloth damped with water.

In order to grant a real safety, a gas detector must be coupled to an electro- valve capable of blocking the gas flow in the event of an alarm.
Both the gas unit and the solenoid valve must comply with the law prescriptions in force in the country concerned.
BEAGLE Plus –S detector can be connected to two types of electro-valve:

230V Normally Open electro-valve;
230V Normally Closed electro-valve;

In order to check the proper efficiency of the device sensor a specific test gas bottle (optional) is made available which must be used according to the enclosed instructions.

WARNING: Any other method for testing, such as the use of cigarette lighters, flammable vapours etc., can lead to wrong conclusions as well as to the irreversibile damage of the sensor itself.

The installer is reminded to fill in and apply the sticking label supplied with the product by writing the installation date of the product, the date before which the sensor module must be replaced, the date before which the sensor module must be replaced the second and last time and finally the date before which the entire detector must be replaced.
The latter is stated on 15 solar years from the installation date of the product.
This label must be applied, at installer care, on a visible side of the gas detector once it has been fixed in its typical installation position.

Warning label:

The sensor module can be replaced only twice and the replacement must be done by qualified personnel only.

WARNING

Tampering of the device exposes to electrical hazard or malfunction.
The appliance must be wired to the electric mains through a switch capable of disconnecting all poles in compliant with the current safety standards and with a contact separation of at least 3 mm in all poles.
Installation and electrical wirings of this appliance must be made by qualified technicians and in compliance with the current standards.
Before wiring the appliance be sure to turn the mains power off.

WARNING! In case of an alarm:

Extinguish all fire sources.
Close main gas valve (either methane or LPG).
Do not turn on or off any electrical light; do not turn on or off any electrical device.
Open doors and windows to increase ventilation.
If the alarm stops it is necessary to search the possible cause and consequently provide.
In case the alarm persists and the cause of the leak cannot be found, vacate the premises and, from external, immediately notify the gas emergency service.

SENSOR REPLACEMENT

Every five years (max twice) the internal sensor module must be replaced with a new precalibrated sensor module.
The replacement must be done by qualified personnel according to the following instructions:

Use the relevant sensor module part:
BEAGLE plus L: AC MG01
BEAGLE plus M: AC MM01
Remove the power supply from the detector.
Remove the detector’s panel as shown in Fig. 2.
Spot the sensor module to be replaced:
Remove the old sensor module, holding firmly the edges of the board and pulling it out:
Insert the new sensor in the relevant connector. Attention must be payed in that the module’s pins match the relevant detector’s female connector.
WARNING: the sensor module must be mounted so that its components face the inside of the detector’s board.
Place back the front panel on the detector and tighten the relevant screw.
Power up the detector and check for its correct operation.
Fill in the detector’s warning label or fill in the new label supplied with the spare sensor module and stick it on the detector.
Note: that the warning label’s date must be 5 years ahead the set up of the new sensor module.
