Monitoring Tower Lights, HVAC, & Radio Systems for a County Fire Department

On this trip to Texas, one of my stops was to a county fire department. When we arrived, we were instantly greeted by the fire chief. Since he is also responsible for the multiple radio sites owned and operation for county public safety personnel, he took out out to 3 tower sites to survey the equipment and plan a remote monitoring system to cover everything.

Multi-Building Alarm Echo to a Single Fire Alarm Control Panel (FACP)

I got a call recently about a six-building complex that, due to local fire ordinance, requires that the fire detection system in each building be linked back to just one conventional fire alarm control panel (FACP). See the two devices that, working together, will pull this off.

He had questions about the specific architectures and I/O we use for measuring temperature. I think that conversation will be useful for you as you research your options for remote site temperature measurement.
