The DXS-54/EC is a battery powered passive infrared motion detector
PRODUCT DESCRIPTION
with a built-in transmitter designed for use with Linear’s DXS and DX 
format receivers. This transmitter can be used in a variety of motion 
detection applications. When the passive infrared sensor detects 
motion in its field of view, the transmitter sends a digitally coded 
wireless signal to its companion receiver.
The digital DXS code format features over a million possible codes. 
The DXS transmitters are precoded at the factory to unique codes, so 
no field coding is required. The DXS-54/EC can send three different 
signals: alarm, low battery and status.
For versatility, any transmitter can be programmed into any receiver 
channel. 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 between six and eight feet high. The sensor will 
monitor the infrared level in its detection pattern. If the level increases 
or decreases rapidly (as when a person or animal moves through the 
area) the transmitter triggers, sending an alarm signal to the receiver.

The unit is powered from a 9-Volt alkaline battery. The battery’s life 
can be up to three years depending on the area’s traffic. When the 
battery gets low, the test indicator will flash and a low battery signal 
will be sent to the receiver when the detector senses motion.
Approximately every hour, the DXS-54/EC 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. DXS format receivers can monitor status 
signals, DX format receivers cannot.
To conserve battery life, during normal operation, the detector can
trigger the transmitter a maximum of once every four minutes.
For setup and testing, pressing the detector’s test button places the 
unit in walk test mode for four 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.
In walk test, an alarm signal is sent each time the walk test indicator 
lights. During normal operation, the detector requires a “pulse count” 
of three events in eight seconds before sending an alarm transmission.

Expiration Date is labeled on the product. This warranty extends only to wholesale customers who buy direct from 
Linear or through Linear’s normal distribution channels. Linear does not warrant this product to consumers. 
Consumers should inquire from their selling dealer as to the nature of the dealer’s warranty, if any. There are no
obligations or liabilities on the part of Linear Corporation for consequential damages arising out of or in 
connection with use or performance of this product or other indirect damages with respect to loss of property, 
revenue, or profit, or cost of removal, installation, or reinstallation. All implied warranties, including implied 
warranties for merchantability and implied warranties for fitness, are valid only until Warranty Expiration Date 
as labeled on the product. This Linear Corporation Warranty is in lieu of all other warranties express or implied. 
For warranty service on Linear equipment return product, at sender’s expense to:

REPAIRS POLICY
Charges will be made for equipment that is not in warranty, shows customer abuse, or is damaged by the effects of 
lightning, water, fire, or other abnormal happenings. 
Customer’s equipment sent in for repair may be repaired or replaced with new or remanufactured equipment at Linear’s 
discretion. 
The customer is always responsible for shipping and handling charges to the repairs facility. Linear will pay return 
shipping and handling charges on “in warranty” products shipped back to the customer. The customer will be billed 
for the return shipping and handling charges on “out of warranty” products. 
There will be a 50% expedite fee for any express requ ests. 
The International Sales Manager must be notified prior to the return of product to Linear. All international returns must 
have an International Repair Authorization number (IRA#). The number must be marked on all packages. Failure to 
do so will cause delays in processing.
IMPORTANT !!!
Linear radio controls provide a reliable communications link and fill an important need in portable wireless signaling. 
However, there are some limitations which must be observed. The radios are required to comply with local rules and 
regulations as radio devices. As such, they have limited transmitter power and therefore limited range. 
A receiver cannot respond to more than one transmitted signal at a time and may be blocked by radio signals that 
occur on or near their operating frequencies, regardless of code settings. Changes or modifications to the device may 
void regulatory compliance. Infrequently used radio links should be tested regularly to protect against undetected 
interference or fault. A general knowledge of radio and its vagaries should be gained prior to acting as a wholesale 
distributor or dealer, and these facts should be communicated to the ultimate users.
