Decide where to install each chassis.
1. Do not place the control chassis more than 100 feet from the transformer. This is the
maximum cable run allowed by the ACS power supply.
2. Calculate the distance between the control chassis and each expansion chassis using
the chart in Table 1 below. The calculations are based on the following restrictions.
a) The control chassis, containing the MAIN BOARD, and the first expansion
chassis can be up to 1500 feet apart.
b) Each time another expansion chassis is added, the maximum distance between
the first and last chassis decreases by 50 feet. So, if there are three chassis in a
system, the control chassis plus two expansion chassis, the two most distant
chassis can be no more than 1450 apart.
Total # of chassis Max allowed distance
2 1500
3 1450
4 1400
5 1350
6 1300
7 1250
8 1200
Table 1. Maximum Distance Calculations
c) Calculate the distance between each chassis and its associated keypad or
reader. The ACS does not specify a maximum distance between the chassis and
a keypad or reader, but the keypad/reader manufacturer does. Follow
manufacturer guidelines for each keypad and reader.
d) Place each chassis within 500 feet of its associated electronic strike or latch.
Follow safety precautions.
