MOUNTING
Install the alarm unit in a 19-inch (48.26 cm) rack. The unit occupies one rack unit (1.75 inches or 4.45 cm) of space. You can mount the alarm unit to something other than a standard 19-inch rack by relocating the rack ears to another location.

CONNECTING TO THE CM6800
Connect the supplied RJ-45 straight cable from the ALM2064 OUT port to the CM6800 COM 3 port. The active pin-outs are associated with the four outer pins: 1, 2, 7, and 8. Refer to Figure 4.
If you want to place the alarm unit some distance from the CM6800, the RS-485 communication from the alarm unit to the controller should not exceed 4,000 feet (1,219 m). You need an RJ-45 wall-block terminal (part number CON12J008Z03G0Z) if operating from a remote site.
To cascade two alarm units, connect a straight cable from the OUT port of the second alarm unit to the IN port of the first alarm unit. The first unit is the one you connect to the CM6800.
