Section 5
Operating the APD8(F)
5.1 Power Separation Jumper Settings
The APD8(F) gives the installer the ability to electrically isolate the Control power from the Zone
Output power. This can be helpful in installations where noise-sensitive devices would be affected by
lock noise.
To isolate the LOCK power input from the CTRL power input, jumpers J1 and J2 must BOTH be
removed.
Note -
If J1 and J2 are out, BOTH power inputs must be wired to a power source. If J1 and J2 are in
place, either the control input or the power input may be used.
Note -
If J1 and/or J2 are missing, the control power and lock power inputs can be connected
together with wire jumpers if power isolation is not required.
5.2 Zone Input Configuration Switch Settings
Each zone of the APD8(F) has a set of DIP switches associated with its input. These switches
configure the input for use with a variety of signal types, however three basic configurations will
cover a majority of applications. See Appendix A for information on configuring additional input
types.
Note -
Only switches 1 through 6 are used for each input - switches 7 & 8 are unused.
Note -
The factory configuration of these switches (Negative Trip Mode) should work for most
applications.
5.2.1 Negative Trip Mode
Negative Trip Mode will cover applications including Dry Contact (NO or NC) and Open Collector
(including Casi-Rusco). To set the APD8(F) for Negative Trip Mode, Switches 1, 2, and 3 should be
ON (Closed), and all other switches should be OFF (Open).
5.2.2 Positive Trip Mode
Positive Trip Mode covers applications where a positive voltage is applied to the input for
activation. To set the APD8(F) for Positive Trip Mode, Switches 4, 5, and 6 should be ON (Closed),
and all other switches should be OFF (Open).
5.2.3 External 12VDC Trip (Isolated)
External Trip Mode covers applications with a completely isolated 12V source as an activation
source. The source may or may not be common-grounded with the rest of the system. To set the
APD8(F) for External Trip Mode, Switches 2 and 5 should be ON (Closed), and all other switches
should be OFF (Open).
