u Door monitor with sounder alert

u Sequential Logic Input (SLI)

The DS160 Series consists of the DS160 Detector
(light gray) and the DS161 Detector (black)
specifically designed for Request-to-exit (REX)
applications. With features such as timers, door
monitor with sounder alert, and pointable coverage,
the DS160 and DS161 have the flexibility to meet the
most stringent REX requirements. The exclusive
Sequential Logic Input (SLI) provides added security
that is not offered in any other REX device.

Functions

Sequential Logic Input (SLI)

The SLI terminal allows connection of a second device
to require sequential detection. This eliminates the
possibility that an object that is slid through the door
or underneath the door will activate the detector. This
input can also be used to lock the sensor if motion is
present outside the premises.

Door Monitor

The sensor can monitor a door contact to allow special
control of the internal relay. For example, if the door is
opened within the relay time period, the sensor can be
programmed to halt the timer. If the door is not
opened within a specific time period, the relay can be
programmed to deactivate.

u Internal vertical pointability

u Wrap-around coverage pattern with precise pattern

control

u Up to 64 second adjustable latch time

Sounder Alert

An integrated sounder can be programmed to activate
if the door is left open too long. The sounder volume is
fully adjustable to 85 dB.

Keycard Input

The keycard input allows the sensor relay to be
controlled from an external source, such as an access
control system or card reader.

Installation/configuration notes

Front View
Mounted on wall above door and mounted on ceiling .
75 m (2.5 ft) in front of the door.

The higher that you mount the unit, the larger the
coverage area. Do not mount the DS160/DS161 more
than 4.6 m (15 ft) above the floor.
Side view of coverage pattern with the unit mounted at

4.6 m (15 ft) above the floor with the lens pointed
straight down.

Coverage Information

The coverage (detection area) varies depending on the
mounting height above the floor, angle of the lens, and
whether the unit is mounted on a wall above the door
or on the ceiling. The coverage is 2.4 m x 3 m (8 ft x
10 ft) The coverage patterns for the detector at a
height of 2.3 m (7.5 ft) are shown. The coverage
pattern increases or decreases with height and
detector alignment.

Notice

When you mount the unit on the wall and the lens
points straight down, some detection zones point
toward the wall and do not detect movement.

The diagrams depict views of the coverage pattern
with the detector mounted at 2.3 m (7.5 ft) above the
floor with the lens pointed straight down. Zones that
are pointed toward the wall are not shown.

Side View
The higher that you mount the unit, the larger the
coverage area. Do not mount the DS160/DS161 more
than 4.6 m (15 ft) above the floor.
