DS160/DS161 Installation Guide High Performance Request-to-Exit Sensors
1.0 Description
The DS160/161 is a passive-infrared (PIR) detector designed for Request
to Exit (REX) interior applications.
The DS160/161 is UL Listed as an access control device under the UL
294 Standard and is listed for Class I for UL Canada under ULC-S319
when it is connected to a UL approved access control system. For C-UL
listed installation applications, the REX detector shall be connected to
ULC-S319 listed compatible devices (i.e. control units, power supply and
locks).
The technology designed into the DS160/161 is based on the principal
that all objects emit infrared energy. The warmer an object is, the more
infrared energy emitted. Its PIR technology allows the DS160/161 to
detect the change in infrared energy that occurs when a person passes
through its field of view.
The DS160/161 has features such as Sequential Logic Input (SLI) to
eliminate unauthorized entry. SLI allows you to arm the detector using any
dry contact device, such as a second detector, card reader, or the access
control system. This provides better control for this type of application.
A built-in sounder can be automatically activated if the door is propped
open. The sounder can be controlled from any dry contact device. The
DS160/161 detection pattern provides dense C-shaped coverage ideal for
most REX applications. In addition, complete pattern control allows it to be
adjusted to a single zone or placed over a doorknob, for example. There
are fifteen possible coverage patterns to accommodate most applications.
This, combined with the ability to monitor the door and intelligently control
the lock, adds considerable security to these types of applications.
The DS160/161 uses Motion Analyzer II signal processing to help prevent
false activation due to environmental conditions. The relay output consists
of two Form “C” contacts that can be adjusted to latch from approximately
0.5 to 64 sec. The latch time features two modes of operation, resettable
(where the relay timer will not time out as long as someone is in the field
of view) and non-resettable (where the relay will remain latched for a fixed
period of time). The relay can also be programmed to fail safe or fail
secure in the event of power loss.
The DS160/161 provides one set of relay contacts specially protected
from EMF (voltage) spikes caused by connecting to inductive loads.
The DS160/161 may either be ceiling or wall mounted, and its pattern may
be aimed and/or masked for more effective use based upon installation
needs. It is not designed as a primary means of exit for emergency egress
applications.
The DS160/161 is available in a light grey (DS160) or a black (DS161)
enclosure along with an optional trim plate (light gray TP160 or black
TP161) that can cover a single gang box. Panic hardware must be used
with this or any other egress device.

Before you mount the unit, review Section 6.0 Coverage
Patterns on page 6 for more information on the placement
and location of the DS160/161.
4. Route the wiring through the base before mounting the base to the
wall or ceiling. Refer to Step 5 on page 2 when using the optional
trim plate (TP160 or TP161).

3.2 Contact Output Wiring
The normal settings of the contact outputs change depending on the
setting of the Relay Mode Switch (S3). Refer to Section 4.3 Relay Mode
(DIP Switch 3) on page 5.

3.3 Wiring Examples
3.3.1 Basic Connection
The basic connection includes the DS160/161, a power supply, and a
magnetic lock. When the sensor sees motion, power is removed from the
magnetic lock. Relay contacts shown with Switch 3 ON (Failsafe Mode)

3.3.2 Spike Protection
EMF (Voltage) Spike-Protected Relay: Use this relay when
connecting inductive loads to the detector. This relay protects the
detector from inductive loads that might deliver damaging EMF
spikes. No additional spike protection is needed.
Non-EMF (Voltage) Spike-Protected Relay: This relay is best used
for non-inductive loads. When connecting an inductive load that is
not spike-protected, such as a magnetic door lock, to the detector,
use either a bridge rectifier (such as a KBL01) or a diode (such as a
1N4007). Refer to Figure 10 and Figure 11.
UL listed magnetic locks typically are already EMF spikeprotected, and therefore do not require the bridge rectifier
or diode as shown in Figure 10 and Figure 11. Refer to the
magnetic lock’s documentation for more information.
Figure 10: Diode Connection
Figure 11: Bridge Rectifier Connection
Failure to spike-protect the detector can shorten the life of
the relay contacts.
3.3.3 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.
For DIP switch settings, refer to Section 4.7 Remote Input Function (DIP
Switches 2, 9, and 10) on page 6.

3.3.4 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.
Turning the sounder on does not affect the relay or relay
timer. The direct sounder input does not remove power
from the magnetic lock.

To ensure the best sound quality from the sounder, tighten
all unused terminals on the terminal strip.
