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.
