I have an alarm system but the horn stays onn until its silenced. My last horn burned out because it was on for 5 minutes. It says it should only be on in 10 second intervals.

What you are looking for is a 'recycle timer'. This is a relay that, when activated, cycles between on and off. If you want to do it cheep what I would do is take a turn signal flasher (the electronic one, not the bi-metal one) and have it drive the horn relay. The horn will honk at the same rate as a turn signal flash. The other problem is that, by law (in our country) the alarm can only sound for a limited period of time, after which it must shut off or the owner will be find for excessive noise.
The alternative is to buy an industrial relay from Agastat, Omron, Potter and Bromfield, etc. One for the horn cycle and one for the alarm time period. Be warned, industrial relays are designed to be rugged and reliable, and come with an appropriate price tag.

This is not the problem with the horn.
The design shall take care to turn off the alarm after 10 sec. or 5 min, which may be configurable.
In my house I have an alarm , where the alarm rings for 2 min at the max. We can reset before 2 min. We can also configure the length of alarm from 2 min to 5 min or continuos (till the battery goes dead).
You can get intermittent alarms in the market. Instead of continuous sound, they give beeps at regular intervals.
Check with the alarm supplier.
