1.4 Smart Battery Pack (Optional)
The RXT-320 transceiver can also be powered by an optional battery pack that enables it to be remotely
mounted without the need for any cables because of its wireless operation. The available battery pack is
Detcon’s plug-in Smart Battery Pack which provides an output of 12VDC (See Figure 5). If installed, the
RXT-320 transceiver will detect the battery and will continuously query the battery pack for remaining battery
life. The battery pack consists of rechargeable Lithium-Ion batteries and is equipped with integrated safety
electronics that include fuel gauge, voltage, current and temperature monitoring circuits.
This “smart”
circuitry continuously monitors the battery’s condition and reports critical status information to the wireless
transceiver via the Modbus™ registers. The battery pack is designed to plug onto an 8-pin Beau connector on
the Model 100 Terminal Board and should not be exposed to outside elements without being housed and
protected.
Only Detcon products specifically designed to utilize these battery packs should be used.
Operating periods before recharge will vary based on devices attached along with the transceiver and the usage
of those devices, but can be as long as 2-3 months and battery life can be up to 5 years before battery pack
replacement is required. Improper use of the battery pack may be hazardous to personnel or the environment
and will void the warranty.

NOTE: The RXT-320 wireless transceiver can also be powered by a customer provided
external DC power source. Refer to section 2.3.1 for more details.
