INSTALLATION CHECKLI STS
Table 2.2 – System Installation Checklist
All equipment has been inspected for damage
All received equipment has been verified against the packing list to ensure completeness
Site installation drawings have been consulted for placement, mounting and wiring details
A power disconnect switch or a circuit breaker has been provided
A lightning protect system is in place
Junction boxes have been ensured to drain condensation properly
Controller has been mounted and positioned to allow adequate clearance to open the cover
Controller has been mounted upright
All screws within the internal controller hardware are tight
No holes have been punched or drilled on the top of the controller enclosure
The photodiode has been located where it has an unobstructed view of the polar sky (north).
Photodiode is located where it will not view direct or reflected artificial light
Photodiode is supported directly by electrical conduit or mounted on the optional Antenna Mounting
Bracket (Kit PN 1905355).
Photodiode is not mounted underneath the controller where it could be shadowed
Photodiode installation is water tight
AM Towers Only:
If the AM tower is “hot,” do NOT connect the ground wires to the beacon power
connector or the controller beacon power connector.
Table 2.3 – Before Applying Power Checklist
Examine installation drawings.
Verify incoming service voltage is the value stated on the ID plate.
Ensure the unit is wired according to the included instructions.
Check all electrical connections for tightness.
Check all terminal strip connections for tightness.
If external alarm detection circuit responds to closed contacts, ensure they are wired to the proper
contacts that close on alarm.
If external alarm detection circuit responds to open contacts, ensure they are wired to the proper
contacts that open on alarm.
Verify alarm wiring has been protected by using shielded wires. Also verify proper grounding of the
shield wire, and that the wires are ran through conduit.
Ensure the white wire of the photodiode is connected to J4 terminal labeled WHT+ and the black wire
is connected to J4 terminal labeled BLK-.
CHECKOUT PROCEDURE
LIGHTING INSPECTION
The FTS 371 FTC SMART has a built in test procedure to aid in performing lighting inspections (LI). The automated
test eliminates the need to disconnect any wires from the unit to test alarm points. The following inspection will
only test devices that the controller is configured for.
