The FP range of conventional motor powered sirens provides a basic solution to address wide area mass alert signalling in hazardous area locations for all industrial, civil, commercial and environmental requirements.

The products are of simple rugged construction and provide a low frequency traditional air raid sound.

Features:

• Audibility range between 135db @ 1 metre, (105db @ 30metres) for the smallest unit to 140db @ 1 metre, (110db @ 30metres for the largest unit. Sirens in this range in increasing order of sound output are the FP6 & FP10 units.
• 475Hz constant tone signal.
• ATEX approved for zone 1 & 2.
• Overall siren standard approval Exd IIG IIC T4.
• Non electrical parts standard approval EExc IIC T1..T6 X.
• Roughly omni-directional sound coverage which peaks in the direction of the front stator face.
• 400Vac +/- 10% 50Hz 3 phase nominal power supply requirement. (Alternative voltages and frequencies available on request).
• Operating temperature range for the FP6 & FP10 units of -20 to +60 degrees C.
• Cast aluminium & steel construction.
• Environmental rating of IP55.
• If the power supply to the sirens is pulsed to enable the siren to produce a ‘wail’ tone then the maximum run time of the siren is reduced from continuous for constant tone to 15 minutes or less.
• Control units can be supplied to enable the siren to produce the ‘wail’ tone signal with associated control switches. The controls are only suitable for locating in a non-hazardous area.
• The Motor windings are tropicalized as standard.
• Anti-condensation heaters for the motor can be supplied.
• The standard siren builds offered are fitted with EExde rated motors but EExd motors can be supplied.
