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.
