Bells and Bells transformers

Bells and Bells transformers
All you need to complete your low voltage installation

The range of bells and buzzers includes modular versions for discontinuous use SM1, RM1, TSM and TSR, suitable for acoustic signalling in residential and commercial sectors, and versions for continuous use SM2 and RM2, which are able to operate continuously for up to 12 hours while maintaining the quality and level of the sound. RM2 and SM2 are dedicated to specific applications such as acoustic signalling in the industry, alarms notification, supervision and intensive use (schools, factories etc...). TSM and TSR versions also include a transformer:
the input is 230V a.c. and the bell is supplied in 12 or 24 V. Bell transformers are made to supply extra low voltage, they are needed to supply power to any discontinuous load in safety extremely low voltage. The range includes TM and TS: TM ensures fail safe operations and excellent safety thanks to the perfect isolation and separation between the primary and seconday circuits. TS in addition has a thermal protection device integrated into the seconday that makes them resistant to short circuit currents.

Main benefits

 Complete: The range of a speciality manufacturer with a global supplier brand, suitable for a wide range of applications
 Compact: Very competitive dimensions
 Safety: Thanks to the perfect isolation and separation between the primary and secondary
 Reliable: Very low voltage variation (reduced compared to the standard’s allowance) to supply also the most sensitive devices

Main features
 Wide variety of different voltages and powers
 Continuous power up to 63VA
 On-off switch on TS8
 SM2 and RM2 able to operate continuously for up to 12 hours maintaining quality and level of sound.
