I’m an installer and I have a super strange problem I cannot figure out and neither can system sensor tech support or honeywell. I’ve been through probably 10+ tech support calls. Here’s what’s going on. The system is pretty simple, it’s a Vista 20P panel, with a 4204 relay board, and a zone expander, and a COSMOD. I’ve wired tons of systems with this setup. When I test the system to set off the alarm, the panel goes into alarm and the keypad goes into alarm and shows the correct alarm zone; however the smokes do not sound. When testing a CO alarm, everything works perfectly and the CO’s temporal 4 chirp as they should, so I am completely at a loss. The horn strobe goes off, the panel resets correctly with a disarm code, I’ve checked my global programming, and my relay programming, even moved to a different relay to see if just that relay was bad. With system sensor tech support they had me just power the COSMOD from a battery, do that, test the smoke, and bam the smokes sound. So they determined it’s the panel. So I replaced the panel with a new one, manually reprogrammed everything, and still the same problem. I’m wondering if anyone has any idea what I could be missing! TIA!
Did you wire the smoke bell trigger to the correct fire output?
I believe so…I mean just like every other system I’ve done, it’s terminal 3 on the panel to the bell in/smk trigger on the cosmod. …
Is your wiring something similar to this?
If so, I think I see your problem.
There is a DIP Switch on the COSMOD that changes how the device responds to signals in the BELL IN terminals. There is BELL OUT Mode, where the COSMOD listens for Temporal Code 3 in the BELL in terminals for the Devices to sound, and there is SMOKE TRIGGER mode, which sounds the devices if there is a signal on the BELL IN terminal. Here is a section from the Manual that talks about the DIP Switch.
Take a look at that DIP Switch and Let us know how that goes.
Yes wiring is exactly this actually.
Right so yes I know about the Dip Switch settings, if I turn dip switch 1 to öff"the smokes sound, but that is not the right setting as they’d be on all the time. I have several other systems almost identical to this and it setup exactly the same way and the smokes sound temporal 3 on alarm as they should. Upon overlooking some of my pictures, I wonder if I have the positve power and aux power mixed up in the way they are wired to the relay. I may have my positive of the Cosmod wired to the NC of the relay, and the Aux Power from the panel to the Com. If I power the Cosmod simply with a battery to the power in, the smokes sound on alarm fine. Thanks for your help!
Ok I totally wired the positive of the cosmod power to the NC instead of the Common of the relay, could that be my problem?
Possibly, Try wiring the Cosmod to the C contact and the NC contact to the power supply.
Yes, I Do see your frustration here, and I am sorry this is not working out for you…
I just don’t understand the reason why the Cosmod does not listen for the Fire Alarm Signal from the bell circuit…
Another Alternative (If possible, Assuming that you have another space for a relay on the 4204.) is to Wire the Smoke trigger the same way as the CO zone. Since the Bell Signal Coding seems to be the problem here, if you have an Uncoded 12v signal powering the Smoke trigger should work as expected.
(It also looks like there might be a malfunction on the COSMOD. Since they are $$$$, I’m trying to provide alternatives with what you already have.)
Hope this helps…
Thank you!
what do you mean wire the smoke trigger the same way as the CO zone? Are you saying wire another relay to the CO trigger on the Cosmod?
It’s just weird that the CO’s work fine, but the smokes do not
Yes, that is what I meant…
