Hamilton Fire still dispatches rural area alarms to Volunteer and Composite stations, and to senior personnel on multiple alarms on 154.250. The problem is that they are using digital numeric pagers. If you monitor that frequency and hear multiple tones and squawking, chances are that is an alarm of some sort. What I've found, the longer the tones, the more serious the call is. This is quite evident on multiple alarms as several pages for senior personnel are sent out. When these tones go off, I check out the HFD twitter feed to find out what the alarm is. Works about 98% of the time.
