Emergency Light & Siren
Emergency lights and sirens are the alert system that tells people something has gone wrong and gets them moving toward safety. When the power cuts or a fire alarm triggers, these devices are the difference between an orderly evacuation and chaos. Hacsons supplies emergency beam lights, motor sirens, hand operated sirens and piezo buzzers across Pakistan. Prices start at ₨1,575 for the Piezo Siren SE 804P and go up to ₨95,000 for the MS 790 industrial motor siren, with every unit built for real emergency conditions, not just warehouse shelves.
What's Included in Our Emergency Light & Siren Range
Our range covers two core families: emergency lighting and audible alarm devices. On the lighting side, you'll find wall mountable emergency beam lights in red and green housings with rechargeable battery backup and UL listed twin head emergency lights with adjustable halogen lamps. On the siren side, we stock industrial motor sirens from the compact MS 190 at ₨1,650 up to the heavy duty MS 790 at ₨95,000, double motor sirens like the MS 690 that hit 170 dB, manual hand crank sirens for areas without electricity and piezo buzzers for smaller indoor spaces.
Most industrial buyers pair sirens with our Fire Extinguisher units and Hoses & Reels when building a complete fire response setup. For facilities that need full evacuation coverage, our Traffic Safety range includes barricade chains and caution tapes for cordoning off emergency zones.
How to Choose the Right Emergency Light & Siren
Buying the wrong alert system is worse than having none at all. Here's what actually matters.
Match the siren to the space it needs to cover. Sound output is measured in decibels at one metre and the number drops fast as distance increases. A 110 dB siren like the MS 190 works for warehouses, workshops and small factories. For large industrial facilities, ports and open yards, you need 120 dB or higher. The MS 690 double motor siren pushes 170 dB at one metre, which is loud enough to cut through machinery noise across a sprawling factory floor. For offices and indoor commercial spaces, a piezo buzzer at 105 dB is plenty. Putting a 170 dB siren in a small office isn't just overkill it's a hearing hazard.
Decide between electric and manual operation. Electric motor sirens run on AC power and integrate into fire alarm panels for automatic triggering. They're the standard for factories, warehouses and commercial buildings with reliable power. Manual hand crank sirens like the Model 12 work without electricity, making them the right choice for civil defence, disaster response and remote sites where power can't be guaranteed. Some facilities keep both electric sirens for daily operation and manual sirens as backup for power failures.
Check the IP rating for your environment. Sirens rated IP44 resist dust and splashing water, which covers most indoor industrial and semi exposed outdoor applications. For fully exposed outdoor installations where rain and washdown are constant, you need a higher IP rating. The MS 790 carries IP44 and a durable metal shell with a pure copper motor that resists heat buildup during extended operation.
Emergency lights need the right backup duration. The Building Code of Pakistan and NFPA 101 require emergency lighting to operate for at least 90 minutes during a power failure. Our Emergency Beam Lights in red and green housings provide rechargeable battery backup with automatic activation when mains power fails. The UL listed LX 690 twin head model delivers at least 1.5 hours of backup with a lead acid battery and 24 hour full recharge time. For stairwells, corridors and exit routes, wall mounted beam lights with high intensity LEDs work best. For large open areas, twin head adjustable lamps cover more ground.
Think about sound direction and coverage. A siren mounted on a wall projects sound in one direction. In large facilities, you need multiple sirens or a rotating mount to cover all areas. The MS 290 has an adjustable air outlet that lets you direct sound up or down. The MS 790 has four pre drilled base holes for solid mounting on any flat surface. For outdoor installations on poles or rooftops, check that the mounting hardware matches your surface.
Our quality checklist before dispatch. Every emergency light and siren that leaves our warehouse goes through a check most suppliers skip. The siren motor spins freely without grinding or hesitation. The sound output matches the labelled decibel rating when tested. The housing shows no cracks, dents, or paint runs. The mounting base is flat and the pre drilled holes align with standard bolts. The wiring terminals are clean and accept cable without forcing. The insulation resistance meets the rated specification. The emergency light battery holds charge and activates within two seconds of power loss. The LED beam is clear with no dark spots or flickering. The test button and charge indicator function properly. And the certification label is legible and traceable to the manufacturer. These checks take three minutes per unit. Skipping them is how buildings end up with a siren that doesn't sound or an emergency light that dies in five minutes.
Plan for testing and maintenance. Emergency systems fail silently. A siren that doesn't sound or a light that doesn't activate is useless when you need it most. Test sirens monthly by triggering the alarm circuit manually. Test emergency lights monthly by pressing the test button and confirming the beam activates. Replace lead acid batteries every three to four years. Clean siren intake vents quarterly to prevent dust blockages. Check mounting bolts every six months for loosening from vibration. Keep a log of every test and maintenance action inspectors ask for it and it's the only way to prove your system works.
Why Buy Emergency Lights & Sirens from Hacsons
We stock alert systems that carry real certifications from real testing bodies. Our LX 690 emergency light meets UL 924 standards and carries a UL94V 0 flame rating. Our motor sirens use pure copper motors that resist heat buildup and last longer than aluminium wound alternatives. The MS 690 supports both AC110V and AC230V with 100MΩ insulation resistance for electrical safety. Every unit ships with mounting hardware and clear wiring instructions. Orders go nationwide and if you're not sure how many sirens your facility needs or what dB level cuts through your machinery noise, ask us. Five minutes on the phone is cheaper than buying the wrong alert system twice.
Frequently Asked Questions
What is the price of an emergency light and siren in Pakistan?
Emergency lights at Hacsons start at ₨7,500 for the Emergency Beam Light in red or green housing and go up to ₨9,000 for the UL listed LX 690 twin head model. Sirens start at ₨1,575 for the Piezo Siren SE 804P and range up to ₨95,000 for the MS 790 industrial motor siren. The MS 190 sits at ₨1,650, the MS 290 at ₨3,100, the manual hand siren at ₨25,000 and the MS 690 double motor at ₨58,500.
How loud should a fire alarm siren be for a factory or warehouse?
For factories and warehouses with machinery noise, you need a siren rated at least 120 dB at one metre. The MS 790 delivers 115–125 dB and the MS 690 pushes 170 dB for large facilities where alert transmission must cut through heavy background noise. For offices and small commercial spaces, 105 dB from a piezo buzzer is sufficient. Always test the siren in the actual environment a rating that looks adequate on paper can disappear in real noise conditions.
What is the difference between an electric motor siren and a manual hand siren?
Electric motor sirens run on AC power and can be wired into fire alarm panels for automatic triggering. They're the standard for factories, warehouses and commercial buildings with reliable electricity. Manual hand crank sirens generate sound without any power source, making them the right choice for civil defence, disaster response and remote locations where electricity can't be guaranteed. Most industrial facilities keep electric sirens for daily operation and manual sirens as backup for power failures.
How long do emergency lights stay on during a power outage?
Building codes in Pakistan and international standards like NFPA 101 require emergency lighting to operate for at least 90 minutes during a power failure. The LX 690 provides at least 1.5 hours of backup with its lead acid battery. The Emergency Beam Lights in red and green housings deliver extended backup duration through rechargeable cell batteries. Test your emergency lights monthly by pressing the test button and confirm the beam activates. Replace batteries every three to four years, or sooner if backup time drops noticeably.
