Warning signals approved
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 aluminium alloy enclosure, which is said to give 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 aluminium enclosure complies with Type B environmental category making it suitable for outdoor installation.
