OUR SAFETY & PROTECTION SERVICES
One of the most overlooked safety devices in your home is a smoke detector. Simply put, a smoke detector is a device that is used to detect smoke. There are basically two types of smoke detector systems, one that has smoke detector wiring that issues a signal to a monitored fire alarm system and the other, known as smoke alarms, generally issue a local audible and/or visual alarm from the detector itself.
Smoke detectors are typically housed in a disk-shaped plastic enclosure, but the shape may vary by manufacturer or product line. Most smoke detectors work either by optical detection (photoelectric) or by physical process (ionization), while others use both detection methods to increase sensitivity to smoke. Smoke detector wiring can be powered by a central fire alarm system, which uses a battery backup, or as is the case in many single family detached and multi-family homes, a smoke alarm is powered only by a single disposable battery.
Smoke detectors are generally placed where they will do the most good. In the United States, most state and local laws regarding the required number and placement of smoke detectors are based upon standards established in the National Fire Prevention Association (NFPA 72) fire code. Laws governing the installation of smoke detectors vary from jurisdiction to jurisdiction. The United States requires smoke detectors on every habitable level and in attics that are accessible, and within the vicinity of all bedrooms. In Canada, it is required that a structure have a working smoke detector on every level.
In new construction, minimum requirements are typically more stringent. All smoke detector wiring must be hooked directly to the electrical wiring system, be interconnected and have a battery backup. Some jurisdictions also require smoke detectors in stairways, main hallways and garages.
Wired units allow a dozen or more detectors to be connected, so that if one detects smoke, the alarms will sound on all the detectors in the network, improving the chances that occupants will be alerted, even if they are behind closed doors or if the alarm is triggered one or two floors removed from their location. Smoke detector wiring with interconnections may only be practical for use in new construction, especially if the wire needs to be routed in areas that are inaccessible without cutting open walls and ceilings.
Most residential smoke detectors run on 9-volt alkaline or carbon-zinc batteries. When these batteries run down, the smoke detector becomes inactive. When the battery is low, most smoke detectors will signal with a chirping sound at regular intervals. In regions that observe daylight saving time, public awareness campaigns suggest changing the smoke detector batteries when they change their clocks.
Some detectors are also being sold with a lithium battery that can run for about 7 to 10 years, though this might actually make it less likely for people to change batteries, since their replacement is needed so infrequently. By that time, the whole detector may need to be replaced.
Homeowners with questions or concerns regarding smoke detector placement, installation or repair should contact their Mister Sparky® technician for assistance. Local fire marshals and municipal building inspectors can also provide information on proper usage and placement.
Called Mr Sparky and they were prompt! We were putting our home on the market and had one issue that needed immediate attention. Within five minutes of arriving they found the problem! Josh was our technician; he was friendly, honest, and courteous. You can trust Mr. Sparky to not only get the job done, but to be fair and not gouge you with high prices. We recently had an electrical storm which caused a power surge and we lost power to a few outlets.
Well my thoughts of Mister Sparky. Well Mister Sparky is definitely on time courteous and very professional. Like one of the family. My first call for any electrical or any Appliance services that I would need. Would be Mister Sparky. Thank you Mr. Sparky.
Prompt, efficient friendly staff, Bryan and George were both a pleasure to meet and do business with. I would most definitely recommend this company. I would also add how impressed I am with the pride they show in the community services they provide. For me that is going above and beyond.
Had a problem with electricity arcing in my main circuit breaker box. All lights upstairs would flicker or go out completely. Luckily, I have a home warranty and the cost will be reimbursed. Called for a repair on a Sunday and a tech was at my house in about an hour or so. He took the time to show me the bad panel and breakers (I could hear the pop and crackle of the electricity). The electrician was extremely friendly and knowledgeable. The Problem was fixed and everything seems to be working fine. I would recommend them in the future.
