DS160/161 Installation Instructions
5.7.2 Wiring Example: Direct Sounder Enable
The Direct Sounder Enable setting can be used to activate the DS160/
161 sounder from a remote contact. The DS160/161 internal sounder
remains on as long as the external contacts remain open. The
sounder input can come from devices such as a door controller or
door contacts. Turning the sounder on does not affect the relay or
relay timer. The direct sounder input does not remove power from
the magnetic lock.

5.7.3 Wiring Example: Sequential Logic Input
The detector only activates by motion when the Sequential Logic
Input (Terminal R) is open, or for 10 sec after it closes. For example,
when a second detector placed before the DS160/161 activates, and
for 10 sec after it resets, the DS160/161 activates when it detects
motion. Any movement after 10 sec after the contact on Terminal R
closes is ignored.

5.7.4 Wiring Example: Monitor Door Contacts (First Option)
In the Monitor Door Contacts Mode, a person entering the field of view
of the detector activates the relay and timer. Door contacts connected
to Terminal D monitor if the door is open or closed. If the relay timer
gets to 10 sec or less (only if set up for 16 sec or greater [see
Section
5.4]) and the door is still open, the DS160/161 internal sounder acti-
vates. The sounder also activates if the door is opened without first
activating the detector or keycard input. The sounder remains on until
the door closes or by someone moving in the field of view.

5.7.1 Wiring Example: DS160/161 and a Keycard Reader
Normally, this setup is used when a keycard reader is on one side of
the door and the DS160/161 is on the other side. Either swiping a
keycard or a motion detected by the DS160/161 removes power from
the magnetic lock.
