The PD
6500

is equipped with solid state switches capable of controlling external alarms,
locking devices, video recorders, etc. Several combinations of switching are available to
allow control of low voltage AC and DC circuits as well as control of logic inputs. Control
is activated when the red Alarm light on the control panel is activated. The control may be
configured to normally open or normally close based on menu settings.
(See
Section 3.5.27.)
7.1
AC CONTrOL
To control devices which require low voltage AC follow Figure 7-1. The optically isolated
triac output is capable of controlling up to 48 Vrms at up to 100 ma. The output is
electrically isolated from the ground.
To connect an external alarm, a locking device, a VCR/video monitor or other AC
component, follow Figure 7-1. The optically-isolated triac output conducts only when the
red Alarm light is illuminated. Control should not exceed 48Vrms and 100mA. The output
is electrically isolated from ground.
Figure 7-1
Procedure:
1.
Disconnect from AC power.
2.
Open access door of detection unit.
3.
Remove the three screws that hold controller cover. Remove the terminal connector.
4.
Connect the relay or device to controller circuit board, as shown.
5.
Replace terminal connector cover and reconnect power.
7.2
DC CONTrOL
To control devices which require low voltage DC, there are three options for
connection.
Cases 1 (internal power), 2 (external power) and 3 (external logic control) (see Figures
7-2, 7-3 and 7-4) show alternatives to connecting an external device that requires a low
voltage, direct current. The output is an open collector configuration that can switch 15V
at 100mA or less, including connections to computing devices and other equipment
requiring low level DC.
