Siren without beacon GPxx series

ruggedpowerful

The GP range of conventional motor powered sirens provides a basic solution to address wide area mass alert signalling for all industrial, civil, commercial and environmental requirements. The products are of simple rugged construction and provide a low frequency traditional air raid siren sound. Features Audibility range between 135db @ 1 metre, (105db @ 30metres) for the smallest unit to 145db @ 1 metre, (115db @ 30metres for the largest unit. Sirens in this range in increasing order of sound output are the GP6, GP10 & GP12 units. 475Hz constant tone signal for the GP6 & GP10 sirens and a combined 475/560Hz constant tone signal for the GP12 siren. 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 standard GP6 & GP10 units of -20 to +60 degrees C and for the GP12 -20 to +55 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. Control units can be supplied to enable the siren to produce the ‘wail’ tone signal with associated control switches. If mounted in a climate where icing can occur the unit should be fitted with thermostatically controlled heaters. The Motor windings are tropicalized as standard. Anti-condensation heaters for the motor can be supplied.
