What are the hours and when should I call?

First Alert operates the call center for this 800-323-9005 phone number Mon-Fri 7am-7pm, Sat 8am-6pm CT. The short answer is that you should call on a Wednesday. This observation and the following section are based on analysis of a sample set of 8 calls made in the last 90 days using our free, web-based phone (see above).

Automatically call when they open

When you use our free AI-powered phone to call and talk, wait on hold, or navigate for you, it will automatically wait until the First Alert call center opens before trying to call. It will ask your permission before it places the call, so you can also further delay that scheduled call until you are ready. But that means you can "set it and forget it" ahead of time.
An important note: busy times vs hold times vs best time to call
When we refer to busy or less busy times, we are talking about the volume of calls. The busiest times are when the most people are calling this First Alert phone number (least busy times have fewer people calling). This high call volume does not necessarily mean that you will have a long hold time when you call. Companies like First Alert staff their call centers differently based on the time of day and day of the week, so you may experience a shorter wait on hold at the busiest of times. When we refer to the best time to call, we are referring to the optimal combination of lower call volume and shorter wait times.

The least busy time to call

The least busy day to call First Alert is Wednesday. The most busy day to call is Monday. Again, this is based on a sample of 8 calls made with our AI-powered, web-based phone in the last 90 days.

The shortest wait on hold

We measured the shortest hold times to be on Friday. The longest wait in the queue on average occurs on Tuesday.
But if you use our free call and talk for me or wait on hold for me service, you don't really need to worry about average wait times.

The best time to call First Alert

In summation, the best day to call First Alert is Wednesday. This is not the day with the shortest wait on hold in the phone system, but we still recommend it for its ideal combination of low call volume and short hold times. Plus we believe that First Alert staffs the call center well on Wednesday.
