Low Voltage Smoke Detectors

Low Voltage Smoke Detector
Important Information You Need To Know: Smoke detector manufacturers recommend replacement of smoke detectors at least every ten years. Research shows thirty percent of detectors fail after ten years, fifty percent after fifteen years!
Years in service Rate failure

  • 1 year 3%
  • 10 years 30%
  • 15 years 50%
  • 30 years 100%

Replacement of Smoke Alarms at Residence 1 and 2 Families. Unless otherwise recommended by the manufacturer’s instructions, one and two resettled live alarms 1 and 2 family stations must be replaced when they fail to respond to these operating tests, but may not operate longer than ten years from the Production Date.

Actually we often call several times to replace the damaged smoke detector, now we know what the reason. This should be a care item that must be planned. How old is your house and detector? The newer design has a latch relay and a temporary silent feature that automatically reactivates itself after eight minutes.
What kind of detector do you have: 120 volts, or maybe low voltage? 120 volt newer 120 volt lower voltage System security Reasoning is that homeowners can easily use their alarm system and therefore do not have a functioning smoke detector at home.
General Information for you.
That more than half of the smoke detectors in the house are not functioning properly. It is a bad battery, or sometimes, people have even taken off the battery!
There are three basic types of smoke detector installations:

  • Battery only (9 volts) that only attached to one ceiling. These are usually found in homes built before 1980.
  • 120 volt ‘Hard-wired’ smoke detector. House built after 1980. Same with the first smoke detector smoke, all detectors go off. In order for you to hear alarms even if you are in another part of the house. In fact almost all of these units have power back up volt volt. If there is a power outage, when people can remove a candle, it’s good to know if the detector still works.
  • Low voltage smoke detector ‘Hard-wired’. It is part of the burglar alarm system. The battery back-up alarm system provides power if the power is now off. This system is best managed by an alarm company. If you have a 120-volt smoke detector, now you can find a good idea. You do not want to try to figure out what the breaker is if you get a false alarm in the middle of the night. Have someone see the power LED when you turn off the breaker until your LED has been off.

Now, What do you do if your smoke detector system goes out?
Check to make sure everyone is safe and there is no fire at all. Sounds simple but you do not want to assume that this is a false alarm right. If it is a false alarm then:

  1. For a single or battery detector, you can try to clean the alarm by blowing or vacuuming around the detector if dust causes problems to your detector. Last is to remove or disconnect power or battery.
  2. Then for an interconnected smoke detector, you need to determine which detector is causing the alarm and try to release it.

Yes .. Different smoke detector models have different methods to indicate which detector is starting the alarm and thus activate all. The key is a red LED indicator light. On some systems, the problem detector will not show any red LEDs while others are steady on LEDs or blinking LEDs. Some systems are the opposite.
Helpful Hints for you:

  1. Try to test your system occasionally. For interconnected units, it helps others to tell whether other detectors are also triggered when you press the test button. They start a second or two after the first. You need to make sure to press the test button on each unit. Even if you experience a lightning attack or surges, be sure to test the detector to verify that their electronic items have not been damaged at all.
  2. Then replace all batteries every 6 months. The occasional chirp sound indicates your battery is weak. Make sure the battery back-up of your smoke detector system is working properly. You need to know if different brands and models vary in terms of appearance and battery power.
  3.  Then if you get an occasional sound and have replaced all your batteries, check also the carbon monoxide detector to see if it requires a replacement battery or not.
  4.  If the detector is more than ten years old, it is important to replace it all. The new detector is 120 volts with a battery backup, can indicate which unit triggers the alarm, and sometimes turns off temporarily for the fault alarm case.
