Supervised Emergency 
Alarm Transmitter
Installation 
Instructions
1. PRODUCT DESCRIPTION
The Model DXS-65 is a supervised  water-resistant emergency alarm transmitter designed for use with Linear’s 
PERS Consoles and can also  be used with other Linear  DX or DXS format receivers. This transmitter features 
a large, easy to find, HELP button. An optional blank face aqua colored button is included for custom labeling or 
alternate  uses. Pressing  the  button  activates the  transmitter  and  sends  a  digitally  coded  wireless  signal  to its 
companion receiver. To insure sending a  complete signal, press  the transmitter button for a minimum of 
two seconds.
The transmitter can be wall mounted using the integral snap-on mounting bracket, or simply be placed on a table. 
Four rubber “feet” are supplied for table-top use. The DXS-65 is factory set to a unique code, so no field coding is 
required. The transmitter can send a signal for up to 10 seconds per activation. The red operation indicator lights 
when the transmitter is activated.
An optional supervisory status timer is included in the DXS-65. Status transmissions occur every two hours and 
inform the receiver of  the condition of  the transmitter and  its batteries. The factory setting  has the status  timer 
disabled. The status timer can  be enabled by pressing the HELP  button continuously for five seconds. The red 
operation indicator  will  blink as  the  status  timer  is  enabled. The  status  timer  can be  disabled by  removing the 
power from the transmitter. NOTE: If the status timer is required for the installation, be sure to enable it after 
replacing the transmitter’s batteries.
Every two hours the transmitter tests for low batteries. This test takes place even if the status transmissions have 
not been enabled. If the batteries test low, a low battery signal is sent to the receiver.
Each transmitter is sealed to provide water-resistance. The transmitter is powered by two 2032 “coin-cell” batteries 
and must be disassembled to replace the batteries.
Before system testing and operation, each transmitter must be programmed into its receiver. Refer to the receiver’s 
or Console’s instructions for details on programming transmitters into the system. When using a PERS or DVS 
Console, be  sure to program the receiver  for the correct sensor type and  supervision option using  the 
RA-2400 programming software. (Note: DVS Consoles default the DXS-65 as an arm/disarm transmitter.)

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.
• ForU.S.installations only:The radios are requiredto comply withFCC Rules and Regulationsas Part 15
devices. As such, they have limited transmitter power and therefore limited range.
