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.

Certifications and approvals

Installation/configuration notes

• The device can be connected to the following panels:
– FPA-5000 / FPA-1200 with NZM 0002 A or FLM-420-NAC
– BZ 500 LSN, UEZ 1000 LSN, UEZ 2000 LSN, UGM 2020

• Doubled screw clips exist for looping-in of voltage.

• FNM-320LED-SRD is not certified to EN 54-23. The beacon is not suitable for fire alarm use within the EU.

• The tones certified according to EN 54-3 are shown in the last columns of the tone tables. The sound pressure levels (SPL) are measured at 28 or 15 V DC at maximum volume and at the loudest node. All other SPL measurements are taken on axis at 1 m and are
not third party verified.
