PRODUCT DESCRIPTION
The DXS-55AF is a battery powered passive infrared motion detector with a built-in transmitter. This transmitter
can be used in a variety of motion detection applications. When the passive infrared sensor detects motion in
its fi eld of view, the transmitter sends a digitally coded wireless signal to its companion receiver. To reduce false
alarms caused by pets inside the protected area, the DXS-55AF features pet immunity with a selectable large or
small pet setting.
The transmitter is pre-coded at the factory to unique codes, so no fi eld coding is required. The DXS-55AF can send
four different signals: alarm, low battery, status, and tamper. Receivers must be programmed to the transmitter’s
code before system testing and operation. Refer to the receiver’s instructions for details on programming.
In a typical installation, the motion detector is mounted indoors in a corner or on a wall 7-1/2 feet high. Two
mounting brackets and an adjustable PIR bracket are included. The sensor will monitor the infrared level in its
detection pattern. If the level increases or decreases rapidly (as when a person moves through the area) the
transmitter triggers, sending an alarm signal to the receiver.
The unit is powered from a 3-Volt Type CR123A lithium battery. The battery’s life can be up to three years
depending on the area’s traffi c. When the battery gets low, a low battery signal will be sent to the receiver.
Approximately every hour, the DXS-55AF will send a status transmission to the receiver. The hourly signal updates
the receiver to the transmitter’s condition. By monitoring status transmissions, the receiver can determine if a
transmitter has a low battery or has been removed from the system.
To conserve battery life, during normal operation, the detector can trigger the transmitter a maximum of once every
three minutes. Opening the case will trigger a tamper transmission.
For setup and testing, pressing the small button on the left side of the case places the unit in walk test mode for
three minutes. The installer can walk in front of the unit while viewing the red test indicator through the detector’s
lens to determine the detection area.

While the DXS-55AF PIR is a highly reliable intrusion detection device, it does not offer guaranteed protection
against burglary. Any intrusion detection device is subject to compromise or failure to warn for a variety of reasons.
The following issues should be considered during new installations or when troubleshooting:
• If the premise has pets, make sure to follow the instructions in this manual concerning installation with pets.
• This PIR has built-in protection, which keeps bugs from getting into the sensor area and causing false
alarms. This does not prevent insects from crawling across the lens of the PIR, which in turn can cause the
PIR to trigger an alarm.
• Infrared energy can be refl ected off any glossy surface such as mirrors, windows, fl oors or counter tops with
glossy fi nish, and slick fi nished concrete. Some surfaces will refl ect less than others will. For example, PIRs
can see a change in infrared energy refl ected off any refl ective surface even if the heat or cold source is not
within the detection pattern of the PIR.
• Windows cannot only refl ect infrared energy, but they can also allow sunlight or lights from cars to pass
through to the PIR. For example, a PIR can detect a quick change in infrared energy if sun light comes
through a window (which may not be detected by the PIR) and shines on a hardwood fl oor (which can be
detected by the PIR). If the change in infrared energy is quick enough on the fl oor, the PIR can trigger an
alarm. The same applies if the PIR “covers” the window, even though the pattern of protection cannot “see”
through glass. Lights from a passing car can also pass through the window at night and directly into the lens
of the detector.
• Heating and A/C ducts are also important to take into consideration because if they blow air onto an object
within the fi elds of view, the temperature of that object could change quickly enough for the detector to see
a change in infrared energy. Detectors cannot see air current, only the change in temperature of a physical
object.
• The PIR senses change in temperature; however, as the ambient temperature of the protected area
approaches the temperature range of 95° to 120°F, the detection performance can decrease.
• Make sure the area you wish to protect does not have obstructions (curtains, screens, large pieces of
furniture, plants, etc.) that may block the pattern of coverage provided by the PIR.
• Anything that can sway or move due to air current can cause a change in infrared energy within the fi elds
of view. Heating and A/C ducts, drafts from doors or windows can cause this to happen. Other objects to be
aware of are curtains, blinds, balloons, loose paper, plants, hanging banners or baskets, etc.
• Make sure the PIR is mounted on a solid surface and does not allow for any vibration. Vibration will not only
cause the PIR to move a little, but this will also cause the fi elds of view in the room to move with respect to
the PIR. A little vibration can go a long way with the fi elds of view, thus the PIR may see a change in energy.
• An installation may require a PIR to be aimed at a door. The PIR may “detect” door movement before the
door contact can initiate an entry delay, causing the PIR to trigger an alarm. If the PIR has to be installed this
way, it is recommended that the alarm control panel program set the PIR as an entry delay.
• The PIR detects intrusion only within the pattern of coverage as diagrammed in this manual.
• The PIR does not provide volumetric area protection.
• The PIR creates multiple beams of protection and intrusion can only be detected in unobstructed areas
covered by those beams.
• The PIR cannot detect motion or intrusion that takes place behind walls, ceilings, fl oors, closed doors, glass
partitions, glass doors, or windows.
• Tampering with, masking, painting, or spraying of any material on the PIR lens or any part of the optical
system can reduce the detection ability of the PIR.
• The PIR will not operate without the appropriate battery installed, or if the battery is weak or improperly
connected (i.e., reversed polarity).
• The PIR, like other electrical devices, are subject to component failure. Even though the DXS-55AF is
designed to last as long as 10 years, the electronic components in it could fail at any time.
