TELGUARD
5.4.2 Connect RJ31X to Telguard Jack 1 and Check LFC
Find the modular Jack-to-Jack (J/J) cable supplied and connect one end to Telguard Jack 1 and
other end to the RJ31X. Note that the
STC
LED goes out and the STC relay returns to normal due to
telco line restoral.
5.4.3 Connect STC Trip Output
Connect the STC trip output (terminals 1 & 2, N.O.) to the 24-hour zone input of C/C.
NOTE:
Activation of a local alarm or strobe light may be desirable when a trip is declared. The
STC trip output can be used directly to activate a local signaling device, provided that the trip
output is not needed to trip the host control/communicator at the same time. If both a local signal
and a control trip input is required, then external relays are needed to provide additional
uncommitted contacts.
