Hosiden Besson Phone Accessory Tonecaller Yellow 3m Lead IP66 Loud Tonecaller 475-101

Hosiden Besson 475-101 Phone Accessory Tonecaller is a specialized loud ringing device designed for telephone systems, delivering maximum output of 105 dBA. Powered from the telephone line itself (60-100 volts AC), it eliminates the need for an external power source or mains connection.

Manufactured with a weatherproof IP66 rating, the tonecaller is ideal for noisy industrial, commercial, and office environments where hearing the telephone ring is critical. It supports two selectable ringing tones: a very fast sweep 120Hz tone and a slower 2.3-2.9Hz buzz tone sounder, both adjustable in volume from 85 to 105 dBA, ensuring adaptable notification settings according to noise levels.

Installation is flexible, allowing hard wiring via screws or insulation displacement connectors (I.D.C), or by utilizing the supplied 3 meter lead with a 431A plug. The product includes a black fixing bracket for mounting convenience. Its robust weatherproof housing allows use in diverse indoor and outdoor conditions without maintenance.

The tonecaller operates solely on telephone line power, minimizing installation and running expenses. The IP66 rating ensures protection from dust and strong water jets, suitable for harsh environments. Two selectable ringing tones offer customizable alerting options.

Volume control enables adjustment between 85 to 105 dBA output levels. Supplied 3m lead and mounting bracket provide easy installation. Ideal for large offices, factories, or other areas with high ambient noise levels. Maintenance free design supports long-term reliable operation.

Typical applications include industrial and commercial telephone systems in loud settings, manufacturing plants, office complexes, and HVAC control rooms. The durable design and flexible installation options make it practical where conventional telephone ringers may be insufficient.
