4 per keypad (more if using optional keypad output or zone input). The ELK kit came with some b-connectors for the keypad.Neurorad said:

As far as sensors, it depends on what you buy. I've found door/window sensors with screw terminals or with flying leads. Maybe some more depending on how you do your EOL resistors.
I bought a pack of 100 dolphin blue and 100 dolphin white on ebay for $18. You can get off-brand ones cheaper. I figure that'll be enough to last me a good long time.
Anywhere there is a pigtail. I tend to use them on fire alarm when tying conductors through, as I like more of a permanent installation 9/10 times.....however many like wire nuts for larger AWG's and solid conductors (as most fire wire is). I also use them to insulate unused conductors in certain applications, where voltage or shorts may be present and safeing the wires with tape isn't desired or suitable for longevity. If you home run devices, each time you series connections. In the case of EOLR's that are located within junctions and heavier AWG conductors are present, always to pigtail to heavier wire. In junctions that aren't likely to have to be torn apart for service/permanent wiring....Connecting telephone lines from a 31X back to house wiring....Neurorad said:
I'll just say in an install large enough for a M1 with expansion and additonal interfaces, I wouldn't blink about blowing through a bag of 100 or two. When I was installing more smaller projects and converting/taking over older installs with lots of junction boxes and plenty of selective rewiring, I could blow through 1000 or 2000 a week easily.
In the specific case of the M1, at the keypad, there's 6 right there, if you don't use a hub and pull enough conductors, the amount to tie the 485 through to the next device (2 per each 485 daisy). If you put EOLR's in the field at the device(s) specifically contacts, there's one there. I tend to wire PIR's as 3 wire many times, however I also use unused terminals in some units as splice points (common in industry if installers are more seasoned in the area, since chicklets cost money!)
Usually, wire nuts are far more common in commercial where splices end up in larger components and junction boxes and are subject to having more components replaced more often.
Depends.
In alarm work, chicklets are usually only used to insulate the splice, not for physical integrity, not to mention, if taped properly, they'll go through a 3/8" hole and still be servicable.
Scotchlocks (U connectors) will only work with solid conductors of specific AWG and they are designed for IDC connections only, also no way to really test without destructive methods. In the case of telecom work, I'd use those first, but for alarm or general purpose....I'd choose something else.

I have said pile on my washer full of shielded Cat6 jacks, boot covers, rack screws, etc...
For Telecom, this is the splicer of the trade:

It comes in different colors depending on the number of connectors; if a Ma Bell employee comes out, this is what they'll generally install. That said I have a ton of chicklets in my bag so that's what I often use - probably annoys them a bit!

Nope, that was just me, but a general rough tally based on how much I would order up. I was doing some very large systems/takeovers where junctions were unavoidable or we were redoing old work with the old bell caps or whatever they chose to install that day, with gel filled units.
I can't see work's link where I am, but the UG/UR/UY's are usually frowned upon by ma bell in my area, they use Picabonds, except for the VDSL work.

The problem with U connectors is a lot of people use dikes or other pliers other than the connector ones and tend to drive the plunger too deep in the connector, causing integrity issues, or in the worst scenarios, cutting through the conductor itself. They'll usually work for a little while, but if the gel is dicey or in a damp/corrosive area, you'll really see the issues show up.
I can think of a bunch of installs where the electricians first discovered them and thought they were better than sliced bread...until the warranty work started and they were shown how they were installed incorrectly by using a micrometer and comparing the right tool to their linesmans or channel locks.
