Simplex 4003 - Mounting and Wiring Peripheral Devices; Procedure

26
Refer to the 841-921 Field Wiring Diagram and the procedure listed below when
installing the 4003 peripheral devices.
NOTE: Use the resistor color code shown in Figure 14 to identify the
EOL resistors used in the installation.
1. Determine the mounting locations of the peripheral devices and install
system wires from the mounting location of each peripheral device to the
4003 panel.
2. Install all peripheral devices and connect them to the appropriate wires.
(Refer to the installation instructions packed with the devices.)
3. For Style Y (Class B) devices, connect a 10K, 1/2W End-of Line Resistor
(EOLR) across the terminals of the last device in the circuit and mark the
device accordingly.
4. If a remote microphone is not installed on this system, terminate TB2 on the
565-358 Voice Controller Assembly as follows:
• 1K, 1/2W resistor from TB2-2 to TB2-3
• 10K, 1/2W resistor from TB2-1 to TB2-3
• 10K, 1/2W resistor from TB2-4 to TB2-5
• 10K, 1/2W resistor from TB2-6 to TB2-8.
