A 3 HP motor siren draws about 2,200 watts, lives outside on the terrace or minar and needs servicing every year. The ABR e-Siren is an electronic siren that draws under 5 watts, sits indoors next to your amplifier and needs no maintenance. Both make the siren sound your mohalla knows. Here is how they compare on everything a masjid committee pays for.
Motor siren vs ABR e-Siren: side-by-side comparison
| Parameter | Motor siren (3 HP) | ABR e-Siren |
|---|---|---|
| How it makes sound | Motor spins a rotor that chops air | Microprocessor-controlled, variable-frequency electronic tone |
| Power draw | About 2,200 W | 5V DC, 300 mA to 1 A (under 5 W) |
| Speakers | Its own housing, on the roof | Your existing amplifier and minar horns |
| Installation | Technician, electrician, wiring to the roof | Two cables, plug ‘n’ play |
| Location | Outdoors, exposed to sun and rain | Indoors, next to the amplifier |
| Yearly maintenance | Bearings, wiring, repairs, climbing the minar | 0% maintenance |
| Vibration | Shakes the structure | 0% |
| During a power cut | Too heavy for most inverters | Runs on inverter or UPS |
| Size and weight | Large and heavy | 10 × 12 × 5 cm, 300 g |
| Warranty | Varies by seller | Lifetime* replacement |
Power: 2,200 watts vs under 5 watts
A 3 HP motor is about 2,200 watts. The e-Siren is rated under 5 watts. In other words, one motor siren draws as much power as more than 400 e-Sirens running at once. That is the “over 98% power saving” (up to 99.99%) you will see on our product page.
To be fair: a siren only runs for a few minutes a day, so the difference on the monthly electricity bill is modest. The power figure matters most in two other places:
- Power cuts at Sehri. A 2,200 W motor is usually too much for a masjid inverter. Under 5 W is not, so the e-Siren keeps working when the power goes.
- Wiring and safety. A heavy motor needs heavy wiring to the roof. The e-Siren plugs into an ordinary socket indoors.
Where the real money goes: upkeep
For most committees, the real cost of a motor siren is not electricity. It is the yearly routine: arranging a technician before Ramadan, climbing the terrace or minar, replacing bearings or rewinding the motor, repairing rain-damaged wiring, and the emergency call when it fails on a Ramadan night.
The e-Siren has no motor, no bearings and nothing outdoors, so there is nothing to service. It is a one-time purchase of ₹4,000, backed by a lifetime* replacement warranty.
Safety
Every year someone has to climb up to a motor siren, often at night and sometimes in the rain. Heavy rotating machinery on a minar also adds vibration and load to the structure. An electronic siren removes both: no climbing, no rotating parts, no vibration.
Sound
A motor siren’s pitch depends on how fast the motor spins, so it takes time to wind up and changes as the motor ages. The e-Siren produces a consistent Hi-Lo wail from the moment you press the button, and you control loudness from the amplifier. It plays through your existing horns, so it reaches as far as your azan does. Learn more about how an electronic siren works.
Verdict
If your motor siren is already on the roof and working, it will keep making noise, but it will keep needing attention too. If you are buying a new siren, or your motor siren needs repair again, an electronic siren that plays through the amplifier you already own is simpler, safer and cheaper to live with.

A 3 HP motor siren draws roughly 2,200 watts while running. Larger motor sirens draw more.
How much power does the ABR e-Siren use?
5V DC, 300 mA to 1 Amp, which is less than 5 watts and less than a mobile charger. That is over 98% less than a 3 HP motor siren.
Is an electronic siren cheaper in the long run?
Usually, yes. The bigger saving is not the electricity bill but the yearly servicing, repairs, technician visits and wiring that a motor siren on the roof needs.
