2000 ECS-6U Controller J85501E-1
4 - 28 Installation and Setup
Issue 4 August 1998
isolated contacts with a common return (TF/ER). A momentary
closure between TEQ and the common return starts equalize. A
momentary closure between TFL and the return stops equalize.
The TR inputs from the external rectifier sequence controller
should be contact closures to discharge ground (DG) to turn off
rectifier groups. In the ECS-6U system, TR1 controls rectifiers
G1 and G5, TR2 controls rectifiers G2 and G6, TR3 controls
rectifier G3, and TR4 controls rectifier G4.
Miscellaneous Outputs: The miscellaneous signals are
basically power (ABS) and ground (DG) to drive the office
alarm system and some of the control inputs to the controller.
The terminal blocks accept 22 to 24-gauge stranded wire. Wire
terminals are not used. The wire ends are stripped and clamped
directly in the terminal blocks. Multiconductor 24-gauge
jacketed cable or 22-gauge twisted pair wire is recommended.
1. Select the desired alarms and other signals. Thus determine
the total number of wires to be connected to the terminal
blocks.
2. Select the configurations of cable and/or twisted pairs
based on the number of signals that are to be directed as a
group to different locations in the office.
3. Route the total wire bundle for the 113A2 through the
opening on the left side of the chassis.
4. Allow for slack in the cable loop outside of the controller,
so that the controller drawer will slide out freely to its full
extent. Approximately 8 inches (200 mm) of cable will be
needed.
5. Strip back the cable jacket(s), if present, approximately
eight inches (200 mm) so that the individual wires reach
their terminal block positions with no tension on any wire.
6. Tape the ends of all extra (spare) wires which are not to be
connected during the initial installation.
7. Strip the remaining wires approximately 1/4-inch (5mm),
insert in their respective terminal positions, and tighten the
terminal block screws. Terminal blocks may be removed
from the control unit for this step, if desired. Note that the
