after talking with my engineer about the relay idea, and looking at how the siren interacts with the LEDs I think that the relay idea is the way forward. We are going to rewire the system so the relays do not also sound the siren. So when the alarm is going off the siren will sound, but once...
woah. That is stupid (edit: meaning super simple) and bullet proof.
If I understand how that works it looks like that could be wired so that a failure in the relay would not interrupt the intermittent alarms (a design requirement) and that a simple power kill at the breaker for the alarm...
Yes, 12v DC deep cycle batteries
The switches are separate, and are at their most basic exactly a set of contacts, although the high heat alarm for the engine room is a little more complicated...
The alarm system is accepting current or no current, no current is no alarm, and when current is...
need 12v alarm system design help --I want the alarm light to stay on for 20 seconds
We have an alarm system on our boat that is very basic, it is 12v and about as simple as it gets.
(float-switch makes a connection when bilge water gets high enough and light and siren go off... Different...
