as a guy who has hired and worked with a lot of alarm service companies, the late night/weekend responses might suck but they pay pretty well.

I typically pay just over $100 per hour for emergency service with a 1 hour minimum. Not bad when the guy comes out and spends 10 minutes changing a faulty detector - which he also sells to me at over 100% markup.

I'm not complaining. It's not my money I spend and the company I prefer to use provides spectacular service. The owner's become a pretty good friend over the years. He's living comfortably.
