The cost of installing hard-wire smoke detectors will vary a huge amount depending on several things:
- Your area of the country (New York and California are high)
- Whether you have an accessible attic
- Whether there is a convenient place to draw the AC power
- Whether external (on-wall) wiring ducts are acceptable
- Whether walls and ceilings are already opened up for remodeling work
The cost could be between $100 or so all the way up to more than $1000.

Hard wired smoke detector versus battery operated smoke detector?
Hard wired detectors are generally better. Some have back up power sources should the city power go out. It depends on how much you want to spend. Hard wired detectors are more expensive to install and are generally built better.
Why would hard wired smoke detectors sound if no smoke is evident?
Hard wired smoke detectors can sound even if there is no smoke present due to a variety of reasons. These can include dust accumulation, a malfunction in the detector, low battery power, or fluctuations in temperature or humidity. It is important to regularly maintain and test your smoke detectors to ensure they are functioning properly.
Do hard wire smoke detectors expire?
Sort of. They need periodic servicing.
How much should it cost to hard-wire two smoke detectors?
The cost of installing hard-wire smoke detectors will vary a huge amount depending on several things: - Your area of the country (New York and California are high) - Whether you have an accessible attic - Whether there is a convenient place to draw the AC power - Whether external (on-wall) wiring ducts are acceptable - Whether walls and ceilings are already opened up for remodeling work The cost could be between $100 or so all the way up to more than $1000.
What are the advantages of hard wired versus battery only smoke detectors?
If the battery dies the smoke detector sill works, that the biggest advantage to using hard wire.
Do wired smoke detectors mount on electrical boxes?
Hard wired smoke detectors have to have a junction box behind them. These detectors use 120 volts as a working voltage. These types of detectors should be wired with 3 conductor #14 wire. The detector uses the black and white wires for the 120 volt source. Detectors these days have an output signal wire that can be connected to other detectors so that if one trips it will sound the alarm in other detectors that are on the same circuit. This output wire can be connected to other detectors by the third red wire in the 3 conductor cable.
Do smoke detectors have to be on a desginated circuit in bedrooms?
Putting smoke detectors on a designated circuit is a good design policy. One of the features of a designated design is that the smoke detectors can be all looped together. The smoke detectors of today have a third terminal where if one detector trips all of the detectors on the circuit have the ability, if connected, to alarm. All of the detectors are wired with a 3 conductor #14 cable. The black and white wires are used for power to the detector and the third red wire is used on the third terminal to alarm all of the detectors on the circuit when one smoke detector trips. With all detectors in an alarm mode it is hard not to hear or sleep through any emergency because of closed doors blocking the sound. Using this method of connection it is recommended a detector in each bedroom and above the stairwell between floors. Keep away from the kitchen area or the whole house will know when someone burns the toast.
Where can you buy smoke detectors?
Check out the smoke detector installation section of this link for more information. Its in section 3. There are many guidelines that may vary from state to state, so you may have to get a local codebook for your state or territory.
How do you smoke loraepam?
You could smoke it if it existed. I think you mean Lorazepam. You should ask you doctor or pharmacist if you are having a hard time.
Why do batteries in smoke detectors have to be replaced in 6 months?
They don't. Normally the 9 volt alkaline batteries in a smoke detector need to be replaced every year. If yours needs to be replaced every 6 months then something is wrong. If you are using a standard battery and not an alkaline battery it may only last 6 months. Use nothing but alkaline batteries. You sould hear a chirp from the detector when the battery needs replacing. A hard wired smoke detector has a battery back-up that should last around 2 years. If it only lasts 6 months then there is no power to the smoke detector and it is wired wrong or the wiring has come loose. The only reason to recommend changing batteries every 6 months is bacuase people tend to not change the batteries as they should. It has been proven by tests that about 35% of smoke detectors in homes have dead batteries.
Why do hard wired smoke detector activate alarm?
A smoke detector is designed to activate an alarm if smoke is detected. It does not matter if the unit is hard wired or battery operated. This is its job. In a hard wired system you can interconnect the alarms if a three wire is used between units. The black and white wires are used to power the unit and the third red wire can be inter connected to the alarms in each one of the other detectors in the same system. Hence if one smoke detector alarm trips, the horn alarms in all of the other detectors will go in to an alarm state. This is a very good safety factor and units should be wired this way. For example if a detector trips in the basement at night and there are closed doors between floors you might not hear the alarm in your upstairs bedroom. If all of the alarms sound upstairs and down no matter which unit tripped, you are bound to hear them, no matter what part of the house you are in.
How much does limo cost?
It can be very hard to buy a limo, and very hard to find one for a cheap price, but it should cost around $5,000 to $10,000.
