INSTALLATION GUIDE
So far in this publication, we have discussed the various documents that are supplied with every new 2120 system.
After studying the examples provided, you should be able to accurately interpret the documents supplied with your
system. Remember: even though there may be many documents provided, they are all interpreted in the same
way as the examples in this publication.
Now that you know how to interpret system documentation, we need to spend some time discussing the installation
itself. Therefore, this segment of the manual is devoted to a general guide for all 2120 installations.
Installation Precautions
Before you install any part of a new 2120 system, there are precautions you need to know and apply to your
particular installation. These precautions are listed below; if you adhere to the rules they provide, your installation
should proceed smoothly and safely.
A. Used twisted, shielded pair for the following:
l
Data lines.
l
Audio and telephone lines.
. RS232C ports.
Note: Monitor Point wiring may or may not require twisted, shielded pair. Refer to the 2120 Field Wiring
Specifications (900-036) for specific recommendations.
B. Each equipment cabinet should be connected to building ground via a single, unbroken conductor (12AWG
wire, typical).
C. DO NOT MAKE ANY CONNECTIONS TO BASIC TRANSPONDERS (BTs), FIRE ALARM BASIC
TRANSPONDERS (FABTs), OR EXPANDED TRANSPONDERS (ETs) WITH POWER APPLIED. This
includes all Monitor and Control Point wiring.
D. Before applying power to new equipment:
l
Verify that power connections have been terminated at the proper terminals.
l
Verify that equipment with a mixture of high and low voltages has all connections properly terminated (for
example, transponders containing low-voltage Monitor Point wiring and high-voltage Control Point
wiring).
l
Verify that all wiring is free of grounds.
E. Apply power to equipment ONLY in the presence of a qualified Simplex Technical Representative and in the
following sequence:
1. Apply AC power first.
2. Apply battery power last.
Reverse this sequence when you power down equipment.
F. NEVER APPLY OR DISCONNECT EQUIPMENT POWER BY USING AN INTERCONNECT PLUG.
G. Do not remove the end-of-line (EOL) resistors on transponder Monitor Points until you are ready to install the
Monitor Point wiring.
