It depends on the circuit that controls the siren. The circuit may be designed for only a 100 watt device and by doubling the current through the circuit, the circuit may be destroyed.
Watt is a unit of power. 1 Watt = 1 Joule/second; joule is the unit for energy.
A watt is a unit of power, not of energy. The international unit for energy is the joule. One watt is an energy transfer of one joule per second.A watt is a unit of power, not of energy.

One watt is an energy transfer of one joule per second.
The word "watt" was named after James Watt, a Scottish engineer who played a crucial role in the development of the steam engine. The watt is a unit of power used to measure the rate of energy transfer or work done.
the answer for the si unit of power is the watt or w
A watt is a unit of power, and it can also be expressed as one joule of energy per second.
1 joule per second = 1 watt
Watt is a unit of power, not a unit of energy. Joule is the SI unit for energy; Watt means Joule/second. So, the "per time unit" is already implied. Saying "watt per second" or "watt per hour" would be completely wrong. The power is simply "900 Watt".
watt
The unit of measurement that represents true power is the watt (W).

The watt unit is called after James Watt.
Watt is a unit of power. watt hours is a unit of energy. (Note x watts times y hours is what you pay for on your electric bill.)
