Jason,
This alarm company is a black eye on the industry. They really shouldn't be in the trade at all.
I'm not sure which current Honeywell panel is equivalent to your First Alert unit but if you'd like to swap it out let me know. I'll have Honeywell send you a new panel at cost.
The "SE" series panels are discontinued. The current panels have a "P" designation. Following are dealer prices on the panels: You'll need a 6160 keypad to program the system. They cost more than some panels.
Vista-10P .. $86.00 Vista-15P .. $91.19 Vista-20P .. $100.39
6160 .. $97.39There are kits that include panel, keypad and a siren or battery. They cost less than just a panel and keypad.
If you ever want to have it monitored in the future there are a couple of companies that charge between $8 and $12 a month. IIRC, their contracts are for one year. I don't offer monitoring.
