schematically in Figure 4-14. Note that the resistor value for OS
is 1000 ohms and the values for RMN and RMJ are 4640 ohms.
Control Inputs: The control inputs from an external equalize
timer panel (TEQ, TFL and TF/ER) must be connected to
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-12U system, TR1 controls rectifiers
G1, G5, and G9; TR2 controls rectifiers G2, G6, and G10; TR3
controls rectifiers G3, G7, and G11; TR4 controls rectifiers G4,
G8, and G12.
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.
1. Select the desired alarms and other signals and 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 113B 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
