Explosion protection - device description

The ExResistTel MB serves for making calls within operating facilities in danger of explosion in the zones: Zone 1, Zone 2, Zone 21 and Zone

22. The telephone is to be realized in the following ignition protection types:

The ExResistTel MB telephone is designated to analogue telephone networks.

The non-secure voltage of the telephone network is led into increased security on the clamps 13 and 14 (A, B). In the call state, this voltage is switched through to the clamps 15 and 16 (Bell shunt1, Bell shunt) with increased security. The clamps 15 and 16 (Bell shunt1, Bell shunt) are designated for the connection of passive loads, e.g. a passive external, explosion protected second alarm.

Furthermore, from the non-secure voltage of the analogue telephone network:

• a secure listener current with clamps within the telephone casing, for the receiver connected with the telephone casing, as well as

• secure circuits with clamps within the telephone casing to connect a secure headset or optionally a secure second receiver, as well as

• a secure circuit with clamps within the telephone casing for the connection to a secure speaker.

The headset, second receiver, external speaker and external secondary alarm accessories are not a component of the ExResistTel MB telephone, but rather can be connected as an option.

Explosion Protection – Device Construction

The ExResistTel MB telephone has an unpainted casing made of electrical-static, conductive press plant material and a stainless steel keyboard.

The casing consists of a box shaped lower part, in which a tub is integrated to hold the electronic system, as well as a curved cover with a keyboard. The cover is pressed under the medium layer of a surrounding seal with four screws on the casing lower part and forms the non-secure and secure connection space. The electronic system conductor board is located in the tub from the casing lower part, which is completely embedded in the compound.

Non-secure connection clamps with increased security:

From the casting, a 4-pin connection clamp series (See connection plan on page 18) comes out in increased security, to connect the non-secure telephone network (A, B), clamp 13 and 14 as well as for the connection for an optional, external, explosion protected second alarm (Bell shunt1, Bell shunt), clamp 15 an 16.

Secure connection clamps:

From the casting, a 12-pin, secure connection clamp series (see connection plan on page 18) comes out to connect the receiver integrated in the telephone casing, clamps 1 to 4, as well as the secure accessories, clamps 5 to 12. The clamps 7 and 8 are intended for the connection of dynamic earphones, as used in second receiver and headsets. This output is therefore optionally used to connect a second receive or a headset, this means second receivers and headsets cannot be connected simultaneously as accessories.

To connect the accessory, the blank plugs installed in the telephone casing are to be exchanged through suitable explosion protected cable and line guides (M20x1.5).

Before the connection of the secure accessories, an evaluation of the security should be executed by the raiser corresponding with the PTB report "interconnection of non-linear and linear security circuits", PTBThEx-10, November 1999 (ISBN 3-89701-440-8), provided no system certificate is provided for the designated interconnection.

The technical data for the evaluation of the security should be taken from the section "explosion protection parameters". Further information see EN60079-14 "electrical operating equipment for gas explosion endangered areas" as well as EN50281-1-1 "electrical operating equipment for usage in areas with flammable dust". When operating the device in explosion dangerous areas with flammable dust, the operator must observe EN50281-1-2 (IEC61241-1-2).

In order to hang up the secure accessories of the second receiver or headset, a metal clamp is designated, which is only delivered together with the headset. In order to mount the metal clamp to the telephone, two screw sockets are placed in the ground of the casing. The metal clamp has corresponding bores, which allows for a mounting on the bottom of the casing through counter sunk bolts (see device overview on page 7). Thus, the raiser must first mount this on the bottom of the casing when using the metal clamp. After this, the wall assembly occurs.

Secure program interface

From the cast, an 8-pin, secure connecting plug comes out (14) (see device overview on page 8). It is only used by the manufacturer for programming purposes. The connecting plug is to be left blank. Programming through the raiser is not permissible.

Secure strand connection to the installed speaker

From the casting, a secure 2-pin strand line (16) (see device overview on page 8), guided to the installed speaker. It is soldered under casting and on the speaker.

Secure strand connection to the reed contact

From the casting, a secure 2-pin strand line (17) (see device overview on page 8) led to a board, on which a magnet contact (reed contact) is found. It is soldered under casting and on the conductor board with the magnet contact.

Secure keyboard connection

From the casting, a secure 14-pin flat band line with connector is guided through (7) (see device overview on page This connector should be placed on the 14 pin pin in the casing cover before the device is screwed down.
