Our colleagues at E2S have announced VDS approval and CPR compliance to directive 305/2011/EU for their AlertAlarm D112 alarm horn sounder by testing to EN54-3. The sounder combines the field-proven electronics of the AlertAlarm A Series with a rugged, corrosion resistant marine grade LM6 aluminium alloy enclosure, providing much improved mechanical and UV protection. The D112 has a maximum Sound Pressure Level of 119 dB(A) @ 1m measured with the nominal 24VDC fire alarm system operating voltage applied; the CPR compliance is valid for operation from 18 – 30VDC. The 48VDC version is also compliant. The VdS approval covers the five most frequently used fire alarm warning tones and also confirms that the units will operate to specification under conditions of dry and damp heat, cold, shock and vibration. The aluminium enclosure complies with Type B environmental category making it suitable for outdoor installation, thus supporting the extension of a fire alarm system into areas other than benign environments thereby enhancing its overall effectiveness and improving safety. Other tests include EMC, SO2 corrosion resistance and dust and water ingress.
UL approved versions for general signalling use are also available. For this version, the aluminium enclosure is sealed to IP66, NEMA Type 4, 4X and 3R.
Ideal for use in a wide range of signalling applications, the AlertAlarm D112 offers a choice of 45 different alarm tones, and includes the option of activating a second and third tone via additional control cables, it is a cost effective and sophisticated signalling solution which provides the versatility of multiple tones from a single unit. It is also available as part of the DL112X, which is the horn sounder integrated with a 5 Joule Xenon strobe, and as the DL112H combination unit, where it is combined with a high output 24-unit LED array beacon.
With more than 20 years experience in the fields of designing and manufacturing sounders, beacons, loudspeakers, voice alarms and disaster warning sirens for the oil & gas, hazardous area, industrial and marine markets E2S continues to offer an expanding range of top quality products and Comsec as their Irish agent will be pleased to offer any assistance you may require in the design of specialised systems.
