Request-to-Exit Detectors
39158H
The Detection Series consists of the DS160 and DS161
Detectors specifically designed for Request-to-Exit (REX)
applications. With features such as built-in 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.
 Features
 Basic 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 detector if
motion is present outside the premises.
Door monitor
The detector 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 detector 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.
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 detector relay to be controlled from
an external source, such as an access control system or card
reader.

The coverage is dependent on mounting height. Typically, the
coverage is 8 ft. x 10 ft. (2.4 m x 3 m).
Typical coverage patterns for the detector at a height of 7.5 ft. (2.3
m) are shown. The coverage pattern increases/decreases with
height and detector alignment.
