Effective June, 2001
6.5 Draw-out Alarm
The draw-out alarm is implemented by use of the spare “N.C.” Ct
terminals. When the relay chassis is inserted in the case, these
contacts are open. When the relay chassis is removed from the
case, these contacts close (self-shorting) thus providing an alarm.
These are the only spare terminals and they have the desired
characteristic of changing state mechanically when the relay
chassis is withdrawn.
6.6 Zone Interlocking Connections
The zone interlocking connection between relays is done by means
of a twisted shielded cable. Downstream Zone Interlock outputs
may be paralleled from up to ten devices (FP-5000 or DT-3000 or a
combination of both) for connection to upstream Zone Interlocked
relays. See Section 8.5.
