Output 2 Not Turning Off

[Digger]

Stef,

I know this sounds silly but double/tripple check you have the resistor across the right terminals. Counting up from the bottom its the 3rd and 4th terminals. From the top down its the 4th and 5th terminals.

The reason I say this is that the relay has 3 connections and I have seen experienced technicians make the mistake of using the 3rd and 4th terminals from the top and then you have this problem. A friend of mine spent about a 1/2 hour on this exact problem and it was that the resistor was across the wrong terminals. I walked over and spotted it after about 2 minutes since I took a fresh look at it.

Good Luck........

You are right Digger,

Sometime, I take for granted that I must be ok and I'm not. But in that case I look again and again and can.

Here is a picture.

I didn't read this entire thread, but I'm a little confused. Spanky mentioned a 100 ohm, 1/2 watt resistor. Is that what you are supposed to use to simulate a siren output?? I'm just not sure and hopefully someone can clarify this.

I THINK you may need a lower resistor if you "just" have that in the in output 2 and no siren, but again, I'm just not sure (i.e. wait for confirmation before you do anything)!

Sorry for the lack of detail, just throwing out a possible trouble point.

Output 2 is a switched negative. The + side is on all the time with +12VDC. The negative side is switched through a FET Power Transistor to Negative. Do not connect the Negative side of the siren to a common Negative or it will stay on all the time.

Output 2 is supervised and has a supervision current running through it. If you measure across Output 2 with a volt meter you will see 12 VDC when nothing else is connected. A speaker or most any resistance up to about 4700 ohms will satisfy the supervision current so that the M1 does not show Output 2 trouble.

Thak you BSR,

Like Spanky said, any resitance up to about 4700 ohms will satify the supervision current.

Question: Does a 2.2k ohms resistor is ok? I think it should be ok since it's less than 4700 ohms...

Ah, I stand corrected. If I read that correctly I would say yes also.

Also curiosity got the better of me and I disconnected the siren from output 2 and placed a 2.2K ohm resistor instead and it indeed stopped the "output 2 trouble" beeping!

It took a few seconds to register though. Are you leaving the power on for at least 30 seconds during your test?

Hi BSR,

There is a 2.2k ohms resistor connection to the panel since at least last week. The M1 keypad never stop showing the output 2 trouble messages.

Yesterday, I have upgrade the firmware, hoping it would help.

When I tried to connect my Ademco wave 2 siren to the output 2, there was current and the siren active. I tried putting a 2.2k resistor accros the -/+ of the output 2 terminal in parrallel with the siren. Maybe I should have placed it in series?

The resistor should be in parallel across the Output 2 terminals. Only put the resistor on Output 2. If it still shows trouble, the output 2 circuit could have a problem.
