So I thought a lot about how to best terminate the powered and unpowered sensors. I liked the ides of terminating all wires at one location and then patching that termination location to the eventual destination (the Elk M1). Plus I was looking for a better way to get distribute power to the 4 wire devices that need it (H2O sensors, motion detectors, etc). I decided to go with the 66-block connectors.
Here are all the wires terminated to the three 66-blocks:
These are split blocks where the right and left sides of the block are not joined. All the alarm leads for each sensor are on the two left 66-blocks I plan to make the green lead the neg. terminal for each contact.
That way I can run a single wire down the length of the 66 block and have just one negative connection for all the sensors. The red/orange wires are numbered for each sensor.
These will be individually connected to the corresponding Elk zone expansion modules which I will mount just below the 66-blocks.
Here is a close up of the terminations
For the powered sensors I used Cat5e wire and ran all the blue/brown wires to the third 66-bock. Will make the blue the + (plus) terminal and the brown the - (minus) terminal (matching number of letters for each to remember which is which). Like before I will only need to run a wire from top to bottom of the inner set of contacts and then will just have a single connection for powering all the devices.
Here is a close up of that 66-block:
I did add up the power requirements of all the devices to confirm I would have adequate power from the Elk panel. I did have a few duplicate numbered wires and had to use my Fluke wire tracer a few times but eventually got it straightened out. I did learn that if I did it again I would number the wires with a leading number to distinguish floor (1xx, 2xx, 3xx). I just numbered them all sequentially and even after reserving a few spare numbers for each floor I still had to add a few wires and now the last few wire numbers unfortunately jump from floor to floor.
