Telephon second ringer
[Type TW2]
The TW2 is built into a shock-proof plastic casing based on protection standard IP 66. The intermittent alarm has a maximum volume of 93 dB (A)/1 m. Because this is significantly different from running machines and motors, it can be perceived even in a loud environment.
