estimating power supply and battery backup capacity for the various components in a Distech Controls
Security System. It is important to properly size the system's power supply and backup batteries. In a
system with distributed expansion modules, cable selection for interconnecting module assemblies is also
important.
If connecting assemblies of modules within the same enclosure, or between adjacent enclosures (same
•
location), a multi-pair, shielded, twisted-pair cable can be used for wiring all 6 positions of the end
connector plugs. For example, use Belden #8725 (4-pair) 20 AWG "reader type" cable.
In this case, connect the RS-485 on one pair (including its shield wire), 15Vdc ("PS-" and "PS+") on a
second pair, and battery backup ("BB") using a conductor of a third pair. In this case, wiring distances are
short, and "voltage drop" considerations can be safely ignored.

Power Up and Initial Checkout

Ensure power wiring to the Remote IO Security module and other components is ready—see the the
and Backup Battery" section on page 14. Following all mounting and wiring, perform the following:
Procedure 2 Initial power up and checkout
Apply Power.

Check the Status
Step 2
Apply Power
Apply power to the Remote IO Security by energizing the connected
6-position end connector plug (wired to power supply) into the module assembly with the Remote IO Security.
Check the Status LEDs
See Figure 2 on page 6 for location of LEDs. When power is applied, the green LED labeled "STATUS" on the
Remote IO Security will begin blinking about 2 times a second. Any blinking indicates that the module has power,

If after applying power, the status LED goes out, and 12–15Vdc power is determined to be present, contact
Systems Engineering for technical assistance.
