Lithium Thionyl Chloride Batteries
Sensys Networks uses Lithium Thionyl Chloride batteries in the
following products:
• SENSORS (VSN240-F, VSN240-T, VSN240-S,
VSN240-M, VSN240-F-2, VSN240-T-2)
• REPEATERS (RP240-B, RP240-B-LL, RP240-BH,
RP240-BH-LL, FLEX-RP-B, FLEX-RP-B-LL)
Lithium batteries are widely used in electronic products because they
contain more energy per unit-weight than conventional batteries.
However, the same properties that deliver high energy density
also contribute to potential hazards if the batteries are damaged.
Improper use or handling of the batteries may result in leakage or
release of battery contents, explosion, or re.
Following are the recommendations of the battery manufacturer for
proper use and handling of batteries in the Sensys Networks devices
mentioned above:
• DO NOT CHARGE OR ATTEMPT TO RECHARGE THE
BATTERIES (BATTERIES ARE NOT RECHARGEABLE)
• DO NOT CRUSH OR PUNCTURE BATTERIES
• DO NOT SHORT-CIRCUIT THE BATTERIES
• DO NOT FORCE OVER-DISCHARGE OF THE
BATTERIES
• DO NOT INCINERATE OR EXPOSE BATTERIES TO
EXCESSIVE HEATING
• DO NOT EXPOSE BATTERY CONTENTS TO WATER
• DO DISPOSE OF BATTERIES AND DEVICES
CONTAINING BATTERIES IN ACCORDANCE WITH
LOCAL REGULATIONS
Sensys Networks sensors contain no serviceable parts and should
never be disassembled. Installation and removal of sensors from
pavement should only be done by trained personnel and care should
be taken to insure that the sensor casing is not punctured or crushed.
Additional safety information is available from the battery’s
manufacturer:

Connect battery cable to circuit-board connector (a). DO NOT PINCH OR
STRESS CABLES. Wait approximately ve seconds for LED lights to blink.
Close cover; ensure wires are not caught in edges. Latch the two hinges securely.

Quick Start Guide: FLEX-RP-B/FLEX-RP-B-LL
• The default radio channel for access
point to repeater communications is
0 (zero).
• The default radio channel for repeater
to sensor communications is 1 (one).
• Never use the same channel for
both access point and sensor
communications.
Refer to Sensys Network VDS240 Wireless
Vehicle Detection System TrafcDOT v2.10 Set
Up and Operating Guide for more information.
Channel Notes
• When an installation contains multiple
repeaters with more than ten sensors,
changing one or more repeaters from
Current Cong 0 to Current Cong 1
allows the repeater to communicate
with up to 20 sensors.

Congure Repeater (cont.)
If the repeater is connected to an external antenna,
then it can be congured via the Adv tab. From the
Antenna window, select either Upstream (to AP) or
Downstream (to sensors) to congure the external
antenna.
Note: Recommended setting for external antenna is
Downstream (to sensors).
Adv Tab
• Internal antenna is not listed on the panel, but will
automatically be assigned to the unchecked option.
• A failsafe error message will occur should you
choose both options.
• If FLEX-RP-B/FLEX-RP-B-LL is installed with
or without the external antenna, and the Adv tab
options are left unchecked, the internal antenna
will be used for both Upstream and Downstream
channels.
• If Discover Mode is not on the following warning
will display: Advanced setting values are either not
set or last known current value because discover
not on. Value(s) will not be updated until discover
on.
• If Discover Mode is off at connection time for
TrafcDOT the Adv tab will display Not Set values.
Turn on Discover Mode for true values to display.

FLEX-RP-B & FLEX-RP-B-LL Repeater
The Sensys Networks Repeater. In cases where installed
Sensys Networks wireless sensors are out of range of the
nearest access point, one or more Sensys Networks repeaters
can be used to provide a two-way relay between the out-of-
range sensors and the access point. A repeater is mounted
by the roadside on a pole or other structure. The repeater is
positioned so that both the sensors and the tandem repeater
or access point are within view and within range.
FLEX Repeaters are second generation repeaters from
Sensys Networks that provide antenna options that extends
the range of the repeaters and eliminates the need for
additional repeaters operating in tandem. The FLEX-RP-B
Repeater is powered with a replaceable battery pack located
within the unit; however the FLEX-RP-B-LL Repeater
does not have a replaceable battery. Both FLEX Repeaters
utilize enhanced RF chipsets and circuitry that improves RF
robustness and reduces energy consumption. FLEX Repeaters
have an internal antenna and connect with the FLEX External
Antenna.
Antenna Options. The FLEX External Antenna connects
to FLEX Repeaters via a coaxial cable. The antenna, which
works in conjunction with a repeater, allows the repeater to
be aimed in two directions simultaneously utilizing a pole
located between the sensor and access point.
Two types of FLEX External Antennas are supported: (i)
the FLEX-ANT-1 with the same RF coverage as the internal
antenna and (ii) the FLEX-ANT-2 with Long Range RF
coverage.
The FLEX family of repeaters work with the standard
repeaters RP240-BH and RP240-BH-LL.
