Section 4 – Basic Hardwired Points
4-5
Referring to
Figure 4-3
, if Break #1 occurs, point 3 goes into a trouble condition, but will continue to
monitor device "A" for an alarm condition. Point 4 will continue to monitor devices "B" and "C" for
alarm conditions. If Break #2 occurs, point 3 goes into a trouble condition and will still monitor devices
"A", "B" and "C" for alarm conditions. The trouble and alarm messages will be sent to the CCC as point
3 trouble or alarm.
To wire points 3 and 4 for the Style “D” configuration, perform the following steps:
Step Action
1 Select UL Listed fire sensors (4-wire smoke detectors, sprinkler system supervisory
devices, etc.).
2
Run the wiring starting at point 3 terminals (29 and 30) through the facility and homerun
back to the control unit to the terminals for point 4 (31 and 32).
3 Connect the fire sensors in parallel along the wire run. See
Figure 4-3.
4 If EOL resistors are presently connected across the terminals, remove them. Connect only
one 2k resistor directly across the terminals for point 4 inside the control cabinet. See
Figure 4-3.
5 Connect the power wires from the fire sensors to the control unit. Connect the ground wire
to terminal 12, and the positive power to the normally closed side of the auxiliary relay
(terminal 9).
Note:
Auxiliary power is not automatically reset after an alarm, and therefore must be
momentarily interrupted using the built-in auxiliary relay.
Programming for Style ‘D’ Configuration
Programming for the Style 'D' configuration may be done via the downline loader.
Point 8 Bell Box Tamper Configuration
Point 8 may be used as a tamper input for the tamper switches and tamper liner on a Grade A Bell Box.
See the
Installing the Control Unit
and
Bell Outputs and Auxiliary Relay
sections for wiring
information.
To program point 8 for the tamper configuration, assign it to a BA group and program the point as a
Day/Nite input type. See the
Programming
section for information about the procedure.
If you are using the bell box tamper, program the option via the downline loader. Otherwise the system will
not detect a "short" on point 8.
