Figure 19. Typical relay output wiring for monitoring separate alarm and fault contacts
Figure 20. Typical relay output wiring for monitoring alarm and fault contacts on a single two-wire input
Notes:
1. The cable shield must be earth grounded at one end only, at the control panel.
Coil and tape the cable shield at the detector end.
2. The alarm relay contacts are shown with no power applied. The alarm relay is
de-energized during normal operation and with no alarm. This relay will energize
during alarm conditions.
3. Fault relay contacts are also shown with no power applied. During normal
operation and with no fault, this relay will energize and the N.O.contacts will
close.
4. Install an E.O.L. device as required and supplied by the fire alarm panel.
