Call came from Guardian Protection about a low battery in the alarm.  Legitimate call.

Call at 3:30 am. No one there

Got a call at 11:39 at night.  Have no idea why..........

Rec'd phone call on a Sunday afternoon. Guardian Security calling because alarm went off at my office and I'm listed as the emergency contact. They sent police to make sure things were alright. Found bathroom window half open. Good call!

I received a phone call from this number.

I called Guardian.  It IS a number they use.  IT IS legit.  Good news!

Live in Arizona! Have received 2 calls from this number, both at 2:45 a.m. Not good.

My alarm is going off! great!

It is Guardian alarm company -- if you have a home alarm, you'll want to answer this call!

Thank you, so much for listing these comments, because i never answer my phone when an unfamiliar number calls.I happen to be at work and saw them calling and google the number and saw these comments and answer an the maintenance man was trying to get the house..Ugh! But once again thanks :-)

It is Guardian Security calling to inform you that your premise alarm has gone off.

Called to let me know the test period was up for our alarm. Did not ask for password

Neighbor has us listed as emergency contact.  Received call to let us know alarm went off, police were coming to check out.  Legitimate caller.

Have Guardian.  Just a courtesy call to let us know their is a low battery on one of our sensors

Got a call, dont own the system. 7:53 AM

i used to work for Guardian Protection and this is their number for their alarm central station...they are probably calling because you set off your alarm, took down a sensor, or you are an emergency contact for someone that has a system.

Caller hang up.... No message.

7:31 am
