Aqualarm makes a range of engine, bilge, and intrusion alarms, much of which works well for retrofit.<\/p>\n

<\/div>\n
On Wind Horse<\/em> we are using their exhaust overheat detectors (a collar which straps around the exhaust line) to give us a warning if cooling water has stopped.<\/p>\n
<\/div>\n
We also use their cooling water flow detectors for the engines and genset, and remote fire detectors.<\/p>\n

<\/div>\n
We have two of these in Wind Horse<\/em>‘s engine room – one between the engines and another further aft, over the generator and diesel heater.<\/p>\n
<\/div>\n
We have used these external engine overheat detector (this last item is mounted on the engine heat exchanger to give us warning of a problem where low engine coolant might not reach the normal heat sensor) for at least 20 years.<\/p>\n

The photo above is of a direct wired smoke detector. These units are hard wired to your DC power system, and close a switch, which then sounds an alarm if they detect smoke. If you have an engine room, like we do, this is probably a better bet than a household unit, as an internal alarm sound would be masked by the engine noise and shielding. We’ve ordered one of these to test on Wind<\/em>Horse<\/em>.<\/p>\n
<\/div>\n
Another interesting product is the “Light Sentry”. This unit senses whether it is light or dark, and turns on a light circuit automatically. Seems like it might be good for anchor lights.<\/p>\n
OK, we agree this looks like an Aqualarm catalog, but this is interesting stuff and we’ve had good luck with it over the years, so we thought you might like a head’s up.<\/p>\n","protected":false},"excerpt":{"rendered":"
