g:
Provide proper strain relief for all wiring not in conduit
.
9. Connect the SAFEPATH
®
Panel to earth ground, following the National Electrical Code and local
codes for the type of system being installed.
Wire gauge selection of the earth ground wiring should involve consideration of all factors,
including maximum allowable wire resistance and length. The panel is tied to earth ground by
connecting the ground terminals to an earth ground. The location of the ground terminals within
the panel is shown in Figure 3-17 on Page 3-16.
Do not connect input voltage to any equipment until the field wiring has been
tested, inspected and approved.
10. Check the integrity of all field wiring. Confirm that the specified cable is installed, and that there is
continuity between required points (no open circuits), with no unwanted shorts to other
conductors, chassis, or earth ground.
a. Verify that the field wiring complies with the instructions of this manual and the
detailed wiring diagram prepared for this installation.
b. Ensure that no unwanted voltages are present on circuit conductors and ground.
c. Test all ungrounded connectors for electrical isolation from ground.
d. Measure and record the resistance of each NAC circuit. Conduct this test reversing
polarity.
11. Install Amplifier Module(s) (SAA-40S, 80S/SE or SALL-15S), Control Module (DCDC) and Digital
Voice Module (MDX-2) in the proper slots on the Mother Board.
12. Conduct the Initial Checkout procedures as described in Section 3-6 – System Checkout.
Initial Checkout
TWO DIFFERENT SOURCES OF POWER MAY BE CONNECTED TO THE
SAFEPATH
PANEL. DISCONNECT BOTH SOURCES OF POWER BEFORE
SERVICING. FAILURE TO DO SO COULD RESULT IN PROPERTY DAMAGE,
SERIOUS INJURY, OR DEATH TO YOU AND/OR OTHERS.
Connect the AC power source before connecting the battery backup power.
Disconnect the battery backup power before disconnecting the AC power source.
Final Checkout
13. Remove all EOLR Resistors on Zones 1 and 2 Audio and Visual NAC Circuits.
14. Connect all Strobe and Speaker NAC Circuits to the proper connections on the SAFEPATH
®
Mother Board. See Figure 3-2 on Page 3-3.
15. Connect all Optional Equipment to the Dual-Circuit SAFEPATH
®
Panel in accordance with each
Installation Sheet.
16. Where NAC Circuit outputs are not being used in the applicable zones connect a Wheelock, Inc.
LISTED 10K Ohm, 1W EOLR Resistor to the terminals on the Mother Board.
