How to connect the SensorSwitch CM-9-R to the M1G

So I'm thinking of use the SensorSwitch CM-9-R. Has anyone connected this to the Elk M1G? I'm just wondering how it connects?
 
I've read the manual and it seems like you have a few options, depending on your overall monitoring goal.

It seems you can 'daisy chain' multiple sensors together and have only one with this relay installed that will then toggle when ALL the daisy chained sensors show no occupancy.

If you are connecting to the Elk, I would register it as a 'normally closed' sensor and connect the brown (center relay tap) and the Violet (During Occupancy, open relay contacts) to an Elk input zone. If you are not using EOL resistors, make sure you select the EOL option appropriately.

Right, if you are going to use rules like this:
[codebox]WHENEVER [time of day occurs]
AND [occupancy sensor] IS NOT SECURE
THEN [take actions. . .][/codebox]
Then you have made the right choice in buying the relay (-R) model unit, and as BSR suggests, you probably want to define the zone as 16-Non-alarm and the "type" as 0-EOL or 1-Normally Closed.
 
OK, forgive me but I'm a software guy so I still don't get how the sensor gets power. Does the Elk provide the 12V power?

Yes, Red(+) and Black(-) to the power bus on the M1. Grey and Brown to a zone input. I am planning on installing these in my bathrooms for occupancy detection.
 
Hi - this is my situation too but I have a SensorSwitch CM-9 (without the relay) It has three wires, one for power, one is common and the third outputs 12vDC (200ma available) when in a "triggered" state for however long the CM-9's time delay is set for.
Can I supply 12 to an Elk Zone for it to sense a change? It doesn't seem right... If I cannot do that, what is another option?

I think that version is meant to drive an external relay that turns a light on/off directly. I guess you could try to add a relay that is powered by the triggered output, but your best bet is probably to send it back and get the relay version.

Thanks Wuench. I happened upon some of these (inexpensively) so I want to make them work -

Anyone have a suggestion for a tiny, cheap, quiet relay? Alternately can I make a simple circuit that will supply a low for an Elk zone?
 
Put an end-of-line resistor across an M1 zone and program the zone for end-of-line supervision. Connect the the negative from your CM switch to the zone negative and the output line to the zone input that is not marked negative(-). When +12VDC is applied to the zone input, the zone will become NOT SECURE or violated.

Write Rules to do whatever you want with the violated zone.

If you need +12VDC to power the switch you can get +12V from one of the auxilliary power terminals.

Spanky - Thanks so much for a simple solution! I thought for sure I wan't going to be able to connect direct to a zone.
Quick question - I have the Elk 4amp PS. Will it matter if the +12v and ground gets used for this? Electrically I think it wil be the same as tying the grounds together between the M1 and the external PS.

Thanks again!
