VdS Approval for Rugged Metal Enclosure Fire System Horn Sounders


E2S Warning Signals has gained VdS approval and CPR compliance to directive 305/2011/EU for its AlertAlarm D112 alarm horn sounder by testing to EN54-3. It combines the field-proven electronics of its AlertAlarm A Series with a robust, corrosion resistant marine grade LM6 aluminum alloy enclosure, giving greater mechanical and UV protection. The D112 has a maximum SPL of 119 dB(A) @ 1m at the nominal 24VDC fire alarm system operating voltage; the CPR compliance is valid for operation from 18 – 30VDC. The 48VDC version is also compliant. The VdS approval covers the five most commonly used fire alarm warning tones and also confirms that the units operate to specification under conditions of dry and damp heat, cold, shock and vibration. The aluminum enclosure complies with Type B environmental category making it suitable for outdoor installation, and so supporting the extension of a fire detection system into areas beyond the relatively benign office environment, improving safety. Other tests include EMC, SO2 corrosion resistance and dust and water ingress.



UL approved versions for general signaling use are also available. For this version, the aluminum enclosure is sealed to IP66, NEMA Type 4, 4X and 3R.



For use in a wide range of signaling applications, the AlertAlarm D112 offers a choice of 45 different alarm tones, and with the option of activating a second and third tone via additional control cables, it is a cost effective, sophisticated signaling solution providing the versatility of multiple tones from a single unit. It is also available as part of the DL112X, in which the horn sounder is integrated with a 5 Joule Xenon strobe, or as the DL112H combination unit, where the horn sounder is combined with a high output 24-unit LED array beacon.
