Wiring
CAUTION
Electrical Shock or Equipment Damage 
Hazard.
Can shock individuals or short equipment 
circuitry.
Disconnect power supply before installation.
CAUTION
Erratic System Operation Hazard.
Failure to follow proper wiring practices can 
introduce disruptive electrical interference 
(noise).
Keep wiring at least one foot away from large 
inductive loads such as motors line starters, 
lighting ballasts, and large power distribution 
panels.
Shielded cable is required in installations where 
these guidelines cannot be met.
Ground shield only to grounded controller case.
IMPORTANT
1. All wiring must agree with applicable codes, 
ordinances and regulations.
2. Do not mount sensor in incorrect environment.
3. Wire according to the applicable controller 
instructions.
4. Erratic temperature readings from a sensor can 
be caused by improper wiring practices. These 
must be avoided to assure proper operation:
•Avoid poor wiring connections.
•Avoid intermittent or missing building earth 
ground.
•Do not mount sensor in incorrect environment.
Connect low voltage wiring from the sensor to the 
appropriate system component terminals using 
solderless connectors. See Fig. 3.
NOTES:
1.
For connections to the W973 Single Zone 
Logic Panel, see Fig. 4.
2.
For connections to the W7080 Multizone 
System, see Fig. 5. 
3.
For connections to the Excel 500 Control 
System, see Fig. 6.
4.
For additional wiring information, refer to the 
appropriate specification.
