Smoke and carbon monoxide detectors are two of the most important safety devices in any home, but only if they are installed correctly. A detector in the wrong location, wired improperly, or running on a dying battery is not doing its job. At Kelley Electric, we install hardwired smoke and CO detectors in homes across the Lehigh Valley so you know they will actually work when it matters.
Why Hardwired Detectors Are Worth It
Battery-operated detectors are better than nothing, but hardwired units connected to your home’s electrical system offer a level of reliability that batteries cannot match. They have a constant power source, they are interconnected so if one goes off they all go off, and most include a battery backup so they stay active even during a power outage.
For Lehigh Valley homeowners, especially those in older homes throughout Allentown, Bethlehem, and Easton, upgrading to hardwired detectors is one of the smartest and most straightforward electrical improvements you can make.
Smoke Detectors: Your First Line of Defense
A properly placed smoke detector gives you and your family time to get out. Fires move fast, and the difference between early warning and no warning can be measured in seconds. We assess your home’s layout, identify the right locations for coverage, and install detectors that meet current Pennsylvania code requirements.
There are two main types of smoke detectors, ionization and photoelectric, and each responds differently to different types of fires. In many cases a dual-sensor detector or a combination of both types gives you the most complete protection. We will walk you through the options and make a recommendation based on your home.
Carbon Monoxide Detectors: Protecting Against What You Can’t See
Carbon monoxide is colorless and odorless. You will not smell it, see it, or taste it, which is exactly what makes it dangerous. It is produced by gas appliances, furnaces, water heaters, fireplaces, and attached garages, and it can build up to harmful levels faster than most people realize.
A hardwired CO detector continuously monitors the air and sounds an alarm before levels become dangerous. For homes with gas appliances or attached garages, which describes a large portion of homes in the Lehigh Valley area, a CO detector is not optional. It is essential.
Combination Units and Whole-Home Coverage
Many homeowners choose combination smoke and CO detectors, which handle both threats in a single unit. We can install combination units, separate detectors, or a mix depending on your home’s layout and your existing setup. Either way, we make sure every floor is covered and that all units are interconnected so the whole house gets the alert at once.
What to Expect When You Schedule Service
When our electrician arrives, we start by walking through your home to assess current detector placement and identify any gaps in coverage. From there, we handle all the wiring, mounting, and interconnection. Before we leave, every detector is tested and verified. The whole process is typically straightforward, and we will answer any questions you have about placement, maintenance, or when to replace units down the road.
Kelley Electric has been serving Allentown and the surrounding Lehigh Valley communities since 2008. We are locally operated, licensed, and insured, and we work exclusively on residential properties, so this is exactly the kind of job we do every day.

Pennsylvania code requires a smoke detector on every level of the home, inside each bedroom, and outside each sleeping area. For most Lehigh Valley homes, that means multiple units. If yours are older or missing from key locations, it's worth having an electrician assess your current coverage.
CO detectors should be installed on every level of the home and within 10 feet of each sleeping area. If you have an attached garage, gas appliances, or a fuel-burning furnace or water heater, those areas warrant extra attention. Our electricians will map out the right placement for your specific home.
Battery-operated detectors are standalone. If one goes off, the others don't. Hardwired detectors are connected to your home's electrical system and to each other, so an alarm in the basement triggers every detector in the house simultaneously. They also have battery backups, so they keep working during power outages.
Smoke detectors are generally rated for 10 years. Carbon monoxide detectors typically last 5 to 7 years. After that, the sensors degrade and the units should be replaced, even if they appear to be working. If you're not sure how old yours are, check the manufacture date printed on the back of the unit.
Yes. Combination units detect both smoke and carbon monoxide in a single device, which simplifies installation and reduces the number of units on your ceiling. They're a practical choice for many Lehigh Valley homeowners, and we can recommend and install the right model for your home.
For straightforward hardwired detector installation or replacement, a permit is typically not required. However, if the work involves new wiring or panel work, permitting may apply. Kelley Electric handles all the necessary steps and will let you know upfront what's involved for your specific job.
Chirping usually means a low battery, but if you've replaced the batteries and the chirping continues, the unit itself may be at the end of its lifespan. Detectors that are 10 or more years old should be replaced regardless. If you're not sure what's going on, we're happy to take a look when we're on-site for service.
