how many smokes w/sounders on elk?

[pjwinstalls]

I am starting my install of 10 4 wire smokes tomorrow. They have sounders and the manual for them states the maximum alarm current is 25ma-90ma. I am putting these on the saux power output on the m1. I am not sure how to figure out if the m1 can handle all 10 of these smokes?

help is appreciated.

Thanks

Well if you call each device 100ma for the sake of "being covered" the total for 10 devices will be 1 amp. Look @ what the aux power is rated, (I don't have it in my head right now) do you have other devices attached to it?
My first thought is that you should consider adding a second PS to your setup. I could be mistaken...

it says that the SAUX is protected by a 1.1 A PTC.

When using smoke detectors with sounders you need a reversing module(s) to have them all sound at the same time and in synch. The power for the sounders can be obtained from either the aux power or the bell circuit depending on the panel and how you choose to wire it. The sounders would not be powered off of the Saux power when using the reversing module. The detectors would be powered off of the Saux and total would be less than 100 ma since they draw microamps in standby for most detectors.

Not sure exactly the numbers in your case since I dont know which model you are using.

Can you provide a few more details in how you are setting this up? How many zones? How many reversing modules? How are you intending to wire the reversing modules etc.

its one zone with one reversing module. It is a DSC reversing module and i followed the instructions that came with it to wire it. It only has one input for power which i connect to the Saux. It has connections on it for monitoring the panel and to trigger it. I wired these two connections to output 3 on the elk. Lastly the two of the wires from the smokes wired directly to zone 1 on the elk which will be a fire zone. I dont see where i could wire a second power input as you stated. It only shows the power coming off the SAUX, into the reversing module, then out to the smokes from there. Sound right??


One other question, am I suppose to put a resisitor across all the zones that are not wired/in use?

Thanks

Ok I never used that model so I dont know it. If it has to come from Saux you are limited to about an amp. An aux power supply switching through output 3 may be necessary. Make sure to supervise the power if you do.

Tomorrow I will look up that unit as I have the DSC disc at work.

I have 10 smokes and the manual for them says maximum current is 25-90ma so 1 amp should be enough i think. Also, i have the dsc EOL relay at the last smoke.

You also need to add in anything else connected. If you have a elk I doubt all youhave is 10 smokes connected to it. Watch the keypads they draw a little if I remember. Also plan for a little future expansion.

I thought the 1amp on SAUX is dedicated just for smokes....I wouldnt think the draw from the keypads would effect it?"

There is standby power and alarm power. The sounders are considered alarm power and there is a 1 A rating for alarm (going off memory and its been a lonnnnnggg day). You have to consider your other alarm power as well (main siren(s) in/outside) and any other devices activated in alarm. You probably do need an aux power supply.

I dont have a siren, just the speaker on output 1. I have tested the system in alarm mode and it seems to be working fine the couple of times I have sounded the alarm. If it is working fine now, can i assume it would continue to unless i added things.? What other type of things drain from alarm power? Still learning here obviously...thanks!
