The FNM-320 Sounders are acoustic signaling devices with a sound transducer
Functions
The integrated sound transducer offers a selection of 32 tone variants, including various wailing tones, diverse signals for fire alarm (e. g. the DIN tone according to EN 457 / DIN 33404) and other special modulations. The tones are set with a 5-pin DIP switch in the signaling device. With a selected tone type, on activation of the second input, the second tone type is switched on. An additional switch provides two settings, either full output or an attenuation of 10 dB(A). Depending on the tone type, volume set, and operating voltage, the sound pressure varies up to a maximum of 112 dB(A). Monitored connection to fire panels is possible. The bayonet lock enables simple mounting.
