Linear DXS-73 Leaflet

DXS-73

The DXS-73 is a photoelectric smoke alarm with a built-in 
transmitter designed for use with Linear’s DXS and DX Format 
receivers. When smoke is detected, the alarm sounds a loud 
local alarm. Twenty seconds after the local alarm sounds, the 
built-in transmitter sends a digitally coded wireless signal to its 
companion receiver. The wireless signal will be repeated every 
20 seconds as long as smoke is still present.
The digital DXS code format features over a million possible 
codes. The DXS transmitters are precoded at the factory to 
unique codes, so no fi eld coding is required. The DXS-73 can 
send three different codes: alarm, test and low battery 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.
The unit is powered by a 3-volt lithium battery. The battery is 
supplied with the transmitter and can power the unit for up to fi ve 
years. Every hour, the DXS-73 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. If the 
battery voltage drops below a preset level the alarm will sound 
low battery beeps and a low battery signal will be sent to the 
receiver with status reports (some receivers can report low 
battery status, others cannot).
