1. Features: Most important purchase criteria for smoke detector

1.1 Types of Smoke Detectors

Smoke detectors are broadly classified into six types- ionisation, photoelectric, a combination of ionisation & photoelectric, projected beam, aspirating, and heat detectors.

  • Ionisation

There is the use of two metal plates in this type. The electronic current between them senses the smoke when it enters the chamber, which triggers the alarm. This type is best when the intensity of the smoke is very high, or you want to detect flames quickly. This nature makes them sensitive to the smoke from cooking and results in a false alarm.

Most people prefer ionisation smoke detectors as they are inexpensive.

  • Photoelectric

Instead of plates & chambers, light-sensitive sensors are used in photoelectric smoke detectors. When this light gets disruptive by smoke, you get notified.

These are most sensitive to fire than smoke. Fire experts suggest using this type as they sense severe fires more quickly and not trigger false alarms.

They cost a bit more than ionisation smoke detectors, but it is worth buying them.

  • Combination Detectors

There are smoke detectors in which the best of both the ionisation and photoelectric are taken.

Ionisation is best when the intensity of smoke is very high, whereas photoelectric is best when the intensity of smoke is low, but its amount could be suffocating.

The combination of two detectors takes care of both situations. Additionally, it can sense more than smoke & fire. It raises alert in case of emission of harmful gases as well such as carbon monoxide, sulphur dioxide, etc.

  • Projected Beam

The projected beam type of smoke detector is not much famous in the modern market. However, their working principle is similar to a photoelectric smoke detector.

The smoke detector with the projected beam continuously emits invisible light beams, and if the direction of the beams is distorted by smoke, the alarm rings.

  • Aspirating

The aspirating smoke detector is gaining popularity with time, and light beams are used in this as well.

Sample air is collected from the surroundings and passed through the bore pipes and further into the testing chamber. The light emitter present in the chamber passes light beams through the sample air. If it gets disturbed, you are alerted.

  • Heat Detectors

Heat detectors are the oldest forms of smoke detectors.

The detectors have a heat sensor, which predicts the temperature of the surrounding air. The sensor is set at a certain threshold, and once the threshold is broken due to high temperature, it gives the fire indication. Heat detectors alert the user only in case of hazardous fire, whereas, smoke detectors, alert the user in seconds after a fire has started.

Heat detectors are not that effective as smoke detectors are, and therefore, they are rarely used these days. Heat detectors are deployed only at places where smoke sensors and detectors can’t be used or in a small space where high-temperature flames are always expected.

1.2 Types of Smoke Alarm

Smoke detectors do not always alert you through loud noise. There are a few types in which you can get smoke and fire alerts, and they are as follows.

  • Beeping Alarms

    The loud beeping noise is the most common way a smoke detector alert people about fire.

  • Strobe Light Alarms

Strobe light alarms are designed mainly for those who need a hearing aid. In this type, bright strobe light and sometimes vibrations are used to alert users to a potential fire.

  • Voice Alarms

If you want a specific voice rather than a generic beeping sound, voice alarms will do the job. At the time of the fire, a pre-recorded voice send the alert and not a beeping sound. People with kids believe that their children may respond better to command coming in their parents’ voice rather than anybody.

  • Smart Alarms

Smart fire alarms provide more than beeping sound alert. They can link your smoke detector to a smartphone app which will alert you when your alarm goes off irrespective of the fact where you are.

1.3 Power Source

There are two types of power sources that can be used used in a smoke detector- battery or hard-wire.

Battery-operated

As the name suggests, a battery is used to run the smoke detector. Battery-operated detectors are easy to install and usually come with DIY instructions. Another benefit is that you will be sure that it will work even in the event of a power outage. However, keeping a check on the battery is essential because the low battery will result in low or no beeping sound.

Hard-wire

The smoke detectors with hard-wire power source call for wire installation. The installation system is a bit tough, and you need to seek professional help for the same. Furthermore, they come with the option of including batteries as well, so that even in case of a power cut, you get the alert. This type is typically used in the case of newly constructed buildings since everything is done from scratch by the professionals, then they can take care of this thing as well.

It would help if you replace smoke or fire alarm every ten years.

3.3 Why Is my smoke detector beeping intermittently?

If your smoke detector is beeping intermittently, then you first need to notice the pattern and then check the manual because different pattern means different alert which varies as per manufacturer and detector model. Some of the common alert examples and their meanings are:

  • A single beep after every 30 or 60 seconds mean the battery installed incorrectly or need replacement.

  • Several beeps in 60 seconds could be a sign of an old detector and might need to be changed.

  • Consistent beeps followed by a short pause means threat.

4. How-To: Usage hints and care instructions for a smoke detector

4.1 Where to put smoke detectors?

Position smoke detectors at the best locations for best results. 

  • Install wall-mounted alarms such that the top part of the detector is less than 12 inches from the ceiling.
     

  • For peaked ceilings, position the alarm minimum of four inches and a maximum of three feet below the peak.

  • If it is a basement smoke alarms, then install it on the ceiling at the foot of the stairs.
     

  • Mount alarm at least 10 feet from your cooking appliances to minimise false alarms while cooking.
     

  • Avoid installing detectors near HVAC ducts, doors, or windows as drafts can interfere with their operation.

4.2 What are the general care and maintenance tips for a smoke detector?

  • Test your smoke detectors every month, and for that, you can set a “first day of the month” schedule on your calendar.

  • If you are not sure about battery life or low battery indicator is missing, replace your batteries twice a year.

  • Gently vacuum the smoke alarm every month to prevent dirt from blocking the sensor.

  • Never paint a smoke alarm. Paint can restrict airflow, and the alarm can have difficulty detecting a fire.

4.3 How to stop the excessive beeping of the alarm?

Despite having no signs of fire, your smoke detector might be going off regularly due to one of the following reasons:

  • Check battery as it might be loose, dying or installed incorrectly.

  • The alarm sensors need cleaning.

  • If the detector is installed near an open window, then the draft might have blow dust or pollen into the alarm sensors.

  • The alarm is in a high-humidity area such as a bathroom, so, due to steam from a hot shower alarm is getting triggered.

  • The detector could be too close to cooking equipment. Steam or smoke from the stove, or heat from an open oven, can possibly trigger a smoke alarm.

  • Your detector might need replacement.
