Federal Signal Informer Relays Not Working

[Bw1332]

Hey folks,

We have a federal signal informer that we hooked a 12v red light up to so we can see in our sleeping area at night when we get calls. The only problem is that the light wont avtivate on alert. I have 13.8v going into the relay 1 common, and the wire going to the lights plugged in to the relay 1 n.o. Still no success, so I even went as far as setting the relays to manual reset. Still nothing. Its only a year old alerter. Any help would he greatly appreciated!

While I have never worked on one of these, I did read the manual.

The relays close briefly for about 10ms on power-up, so does the lamp flash briefly then? You may have to be in a dark room to see this if you're using incandescent bulbs.

Other problems could be programming - you may have to tell it what alert each relay is to activate on.
Or the relay could be bad. It can handle 5A, so unless you hooked a automotive headlamp to it, it's unlikely you fried the contacts.

If the above doesn't help, you can send it back for repair, or you can crack it open, and see if the relay coil is getting voltage when it's supposed to activate. You may get lucky and find a bad solder joint, or a driver transistor that provides voltage to the coil is bad.
