Smoke Detector Services

Hardwired smoke detectors connect to your electrical system with battery backup. When one senses smoke, all interconnected units sound simultaneously.

What This Service Includes

Three of five home fire deaths occur without working smoke detectors. Battery-only units depend on batteries people forget to replace.

D & D Electric installs hardwired, interconnected systems—continuous power, battery backup, whole-home alert when any detector triggers.

Frequently Asked Questions

How often should smoke detectors be replaced?
Every 10 years regardless of function. Sensors degrade over time, becoming unreliable.
Where should smoke detectors be installed?
Each bedroom, outside sleeping areas, every level including basement. Ceiling-mounted, away from vents.
What's the difference between smoke detectors and smoke alarms?
Terms used interchangeably. Alarms are self-contained; detectors connect to monitored systems. We install both.
Do I need carbon monoxide detectors?
Pennsylvania requires CO detectors with fuel-burning appliances or attached garages. We recommend combination units.
Can you interconnect my existing battery detectors?
No—battery units can't be hardwired. Need hardwired replacements for true interconnection.
Why do my smoke detectors false alarm?
Kitchen steam, dust, insects, or age-related degradation. Relocate, replace aged units, or use photoelectric near kitchens.

What Our Customers Say

"D&D Electric has become our go-to electrician service. We first worked with them a few years back when we had an issue and other contractors couldn't schedule us and D&D by contrast came out the next day and did quality work for a reasonable price and were friendly and personable throughout."
