2. Connecting Form C Dry Contacts

All ServiceTrack units come standard with two sets of Form "C" relay dry contacts for the suppressor status and one set of
Form "C" relay dry contacts for the commercial-power status. These contacts are for connection to a user-provided remote
alarm and monitoring circuits. The relay contacts are rated 110V DC/125V AC with maximum switching power of 30W
DC/62.5VA AC.
Fig. 8 Remote Monitoring Terminal Block
(contacts shown during normal
conditions with power energized)
Figure 8 shows the state of these dry contacts in normal energized conditions. When all suppression and filter modules are
functional and power is present to all phases, terminals "1 and 2" and "4 and 5" are an open circuit while terminals "2 and 3"
and "5 and 6" are a closed circuit. The contacts change state when one or more modules have failed.
Similarily, when input power is present in all phases, terminal "7 and 8" are an open circuit and terminals "8 and 9" are a
closed circuit. The contacts change state when the unit is encountering loss of power to one or more phases (less than 50%
of nominal voltage for duration of 10 cycles).
The installer must provide the appropriate raceway and wiring for the monitoring circuit, observing the restrictions and con-
duit openings illustrated in an earlier section of this manual. The installer must route the monitoring conductors to the ter-
minal blocks on the door-mounted main monitoring board. Route the wires to allow the door to open and close properly.
Tighten screws on terminals to 4.5 in-lbs (0.5 Nm). See Fig. 9 for the Form "C" contact configuration. The annotations on
the diagram match the markings on the terminal block.

3. Verification and Power Up

Apply power to ServiceTrack by closing the circuit breaker or molded-case switch feeding the suppressor.

For Standard Units
Verify that all indicating lights, "COMMERCIAL-POWER STATUS" and
"MODULE STATUS", are illuminated.
For Units with Audible Alarm Monitoring Option
Audible alarm should not operate under normal conditions. The audible
alarm can be "muted" by pressing the "ALARM SILENCE" button, which
subsequently will illuminate the "ALARM SILENCED" light. Pressing the
"ALARM SILENCE" button again will enable the alarm.
