Sentinel Fire & Security was established in 1976 by Galen Hanselman in a small office in Hailey Idaho as the microprocessor was first introduced into electronic security detection industry and moved the office to Ketchum in the mid 1980’s.   In 1989, Mr. Henry Nicolai, who graduated locally from The Community School, purchased the business moving it once more to a North Main Street location. In 1999, he purchased Ketchum Alarm Company, another local company that was established in 1982 by Mr. Tom Bowman, and moved the business to a purpose built office on Lewis Street in Ketchum’s light industrial area.  Mr. Bowman now serves as Sentinel’s general manager

A small local company, Sentinel Fire & Security employs three full time installer/technicians (adding one or more helpers during the busy summer construction season), one full time office manager, five monitoring dispatchers as well as the general manager.

We are licensed in the State of Idaho and all of our technicians have specialty state electrical licenses.  We also maintain an Idaho public works license.

Our office in Ketchum is staffed 24/7/365 and we have four technicians living in Blaine County able to respond to after-hours service calls.  When you call our local number, 726-4788, you will get someone answering the phone in our office in Ketchum.  We do not own a telephone answering machine or voice-mail system because we never need them.

Many years ago, the owner of the company made the conscious decision to handle the monitoring of the alarm systems installed in Blaine County locally and we now provide that service for well over 2500 local customers.  Our monitoring station, although not having an expensive (for our size) UL listed pedigree, is a secure facility and has full redundancy in receivers and power generators.  We will not be affected by other power failures or telecommunication failures outside our region.  We also have a local network of radio transceivers as an option to our customers, to provide backup in the case of a premise or local telephone outage.

We are proud to be a locally owned and operated company and look forward to many more years in service to our community.
