One of my best boat upgrades ever!
I purchased the Siren system because I nearly lost a battery bank over a winter season. I thought it was charging, but there was a shore power failure and it wasn't. I wanted the ability to be proactive and monitor critical systems such as house and start banks, bilge, high water, entry alarm, etc. The Siren system was the only one that seemed to be comprehensive, and offer all of the features I wanted. The price was reasonable, install was easy, and thus far it has performed flawlessly. I get daily reports on the status of all systems and couldn't be more pleased so far.
