The speech module 20-9215 from Telecom Behnke is a rear-mount module for the Series 20, specifically designed for sound broadcasting in elevator cabins. It serves as a speaker module that can be integrated into existing emergency call systems to enable acoustic feedback or communication in emergency situations. The module is designed in size 1 (small) and features an integrated connection plate, enabling direct connection to existing emergency call buttons. The installation solution is intended for use in elevator systems, requiring that a Telecom Behnke BNOS elevator emergency call telephone is already installed in the cabin.

Applications

The module is primarily intended for use in elevator cabins, where it functions as a supplement to an existing emergency call system. It enables acoustic signal transmission, for example, to confirm an emergency call request or to transmit voice messages. Its use is within safety and communication systems in buildings, particularly in elevator installations equipped with an emergency call system. Size 1 is suitable for compact installations where space-saving is a priority.

Functions and Equipment in Detail

The speech module features an integrated connection plate, enabling direct electrical connection to an existing emergency call button. This allows the module to be integrated into existing systems without additional cabling. The speaker's power output is one-third of the power output of the speech module size 3, which is sufficient for use in smaller spaces such as elevator cabins. The module is black in colour, allowing for discreet integration into the environment. The module is designed for rear-mount installation, meaning it is mounted behind a front panel or enclosure.

Technology Explained Simply

The module is designed as a rear-mount module, meaning it is mounted behind a front panel or enclosure, with the operating elements (speaker, microphone) accessible through corresponding openings in the front panel. Dimensions are 132 mm (height) × 55 mm (width) × 43 mm (depth), with measurements taken without cover. The spacing between speaker and microphone is 79 mm, enabling standardized mounting. The connection plate is already integrated, so no additional components are required for electrical connection.

Compatibility and Accessories

The module is specifically designed for integration into systems of the Behnke Series 20. It is compatible with existing BNOS elevator emergency call telephones from Telecom Behnke, with installation requiring that such a telephone is already installed in the cabin. A patch cable of length 3 m is required to connect the module to the emergency call system, available under order number 20-9301. The module is not intended for use without an existing emergency call system.

Installation and Mounting

Mounting is done in rear-mount configuration, with the module fixed behind a front panel or enclosure. The 79 mm spacing between speaker and microphone allows for standardized mounting. The integrated connection plate enables direct electrical connection to an existing emergency call button. Installation requires the use of a patch cable (order no. 20-9301) to connect to the existing emergency call system.

Operational Advantages

The module offers a compact and integrated solution for sound broadcasting in elevator cabins, enabling the use of an existing emergency call system. The integrated connection plate reduces installation effort, and the speaker's power output is sufficient for use in elevator spaces. The black painted surface ensures discreet integration into the environment. Compatibility with the Behnke Series 20 ensures seamless integration into existing systems.

Scope of Delivery

The product is delivered as speech module 20-9215, including integrated connection plate.
