unscrew the enclosure cover, exposing the field wire terminals.
2. Ensure the connections between the Heat Detector and
Terminal Block have not become loose during shipping,
tighten as required.
3. Strip 0.3" (7.6mm) of the insulation from the ends of
Input connection A & B.
4. Insert field wire through port.
5. With a flat tip .14 (3.6mm) screw driver, loosen Input connection
A & B set screw.
6. Insert the exposed end of input connection A and B into
the terminal block as shown.
7. Tighten locking screws hand tight plus 1/4 turn.
8. Thread Heat Detector cover hand tight and tighten.
9. Secure cover in place by tightening the locking set screw
