Protecting our Community since 1976
In 1976, Wilbert Wilson started a small alarm company in Murphys California; today Signal Service is the largest family owned alarm company throughout the Sierra foothills. Owned and managed by Wilbert’s three sons, Andy, Mark and Will who have made Signal Service the success it is today.
We measure our success by the quality of our relationships and service to our customers, and look forward to the opportunity for continued service in the years to come

UL Listed Fire Alarm Company
When it comes to Fire Certification, we adhere to the utmost industry standards. We have worked hard to become UL Listed so that we know we are providing our customers with the best in Fire Protection
Our Monitoring Central Station is locally owned and operated
We do not outsource to another state or country. You will be speaking to a live person 24/7 to assist you with your emergency.
We employ our own Technicians
From installation to service to ongoing inspection and maintenance; we hire, train, and develop our own employees. Most alarm companies will outsource their work to sub-contractors so you never know who will be entering your home or business.

We only install reputable equipment that is made in America, however, if for any reason the equipment fails due to no fault of your own, we will replace the equipment for up to one year.
Responsive Customer Service
When you call our office, you will be greeted by a live person immediately. We strive to answer the phone immediately when our customers call, and not let the phone calls go to an automated answering prompt.
