TYPICAL SYSTEM APPLICATIONS
The following typical applications are examples only.
See Figures 22, 23 and 24. For assistance in adapting a
system to your individual requirements, contact the Field
Support Group at Detector Electronics.
The system illustrated in Figure 22 furnishes solid state
output signals from zones 1 to 5, Fire Logic A and B, and
the Alarm output. External Inhibit and External Accept
are shown connected for use in locations remote from
the controller. Other connections are not used in this
configuration.
External Inhibit/Reset (terminal 44) is a means of remotely
inhibiting the output circuits and resetting the controller.
External Accept (terminal 47) is a means of remotely
turning off the alarm output. These functions can be
performed by a computer interface, external switches, or
any interface that drives the input to less than 0.5 vdc.
Outputs Inhibited (terminal 45) is an output that is driven
low when the controller is in the Outputs Inhibited mode
(keylock switch in TEST or RESET position or External
Inhibit/Reset switch closed).
The system illustrated in Figure 23 furnishes solid state
output signals from zones 1 to 3, Fire Logic A and B,
and the Alarm output. External Inhibit and External
Accept are shown connected for use in locations remote
from the controller. Other connections are not used in
this configuration. In this illustration the detectors are
connected using a 3 wire shielded cable, with the shield
functioning as the C-lead.
NOTE
Wiring codes in many areas do not permit the
detectors to be wired using the method shown in
Figure 23. Therefore, this should be considered an
alternate method for use only where codes allow.
The system illustrated in Figure 24 furnishes solid state
output signals from zones 1 through 8, Fire Logic A and
B, and the Alarm output. External Accept and External
Inhibit are shown connected for use in locations remote
from the controller. Other connections are not used in this
configuration.
