Exterior Keypads for Elk

[Sacedog]

I am looking for a keypad, that I can mount to the exterior of the house, and that would interface with the Elk. I would like to be able to use this for my garage doors, instead of the battery operated ones that come with the garage doors.

Is my best bet a M1KPAS in a weatherproof enclosure? I was hoping for something that didn't require a weatherproof box.

What about a weather proof prox reader?

Good thread...don't know why I didn't find that one when I was searching. So with the Rosslare keypads, how do they connect to the Elk? In other words, how does the Elk see the numbers that you press on the keypad, so that when you press 1234, it knows to close the relay, thus opening the garage door.

These (the Rosslare and the Essex keypads that I've used) are keypads with a "prox" or wiegand interface. They would connect to the prox reader connector on a standard elk keypad located inside in the same general area.

You'd define additional users using the prox equivalent "code" for the numbers you want entered and then use rules to trigger the relay.

For example:

WHENEVER ACCESS Garage Keypad (KP 5) IS TRIGGERED
  THEN TURN Output 197 ON FOR 5 SECS

In this case Output 197 is the single output available on the internal keypad, connected to your relay.

All of these exterior devices communicate with specific Elk components (any Elk LCD keypad or the Elk M1KAM door access module) via the Weigand protocol. Some of these exterior devices can mount over a single gang wall box, and others are surface mount. There are combination devices capable of either PIN inputs or prox card inputs. You must use Elk RP to setup rules for how to handle the Weigand access as poster gcimmino suggested. Via Elk RP, you can program access, such as operating a door strike relay, and you can even allow arming/disarming of the alarm.

Here is something that I haven't yet seen recommended: For maximum flexibility, home-run two cat5 cables to each intererior keypad from your Elk panel. A second cat5 cable home-run to each interior keypad allows you to connect to the extra input, output, and prox reader interface on the Elk LCD keypads. Be aware that there are length limitations to the Wiegand lines however. Also home-run at least one cat5 cable to any proposed exterior keypad location, and at least one cat5 cable to the wall mount garage door opener buttons.

Good luck. The ElkM1 is quite a powerful system. It has taken me a full year to grasp the capabilities of the system that I installed, and I continue to learn.

A bit off topic, but what's is the pre-wire for an electric door strike? Can cat5 do the trick??

Single 24 ga conductor from cat5 would be too small to adequately power a door strike over any appreciable distance. However, if you skillfully bundle the 24 ga conductors together (say put all the solid color jackets together as the positive and all the striped jackets together as the negative), then you have the equivalent of 2 conductor, 18 ga wire which should be fine for lengths up to several hundred feet. Bundling 24 ga wires is extra work, and you need to decide if you want this extra work as opposed to just wiring it with 18 ga wire.

Depending on the strike you choose, you may want to run a larger guage pair for the strike and cat5 for sensor/monitor hookups. I've used the RCI strikes with latch monitor and keeper monitor. These let you monitor that the door is closed and no one has taped the latch in, defeating the lock.
