1.0 Description
The Teledyne Detcon SW-A2V2-DV2 Alarm Stations are wireless, battery powered alarm stations with a two
Strobes and a Horn that can provide 2 of 32 possible alarm tones. The unit is designed for installation and use
in corrosive work environments.
Figure 1 Basic Wireless Alarm Stations
The alarm station can be positioned almost anywhere, since the wireless ability of the unit means that there is
no need for running conduit or outside connections. The alarm station is powered by two internal battery packs.
Communication is performed via Detcon RXT-320 transceivers. Access to the unit is only necessary for general
maintenance and battery exchange/recharge.
Internal wiring between components runs through the Wireless Alarm Interconnect PCA(s). This PCA controls
the state of the alarms via communication with the Wireless Transceiver. When an alarm is triggered, the
wireless transceiver will provide the interconnect PCA with the signal(s) necessary to activate the proper
alarm(s).

SW-A2V2-DV2 Instruction Manual Rev. 1.4 Page 2 of 11
The RXT-320 Transceiver has a rotary switch on the Wireless Alarm Interconnect PCA that is used to set the
Modbus Address of the alarm unit. Each Wireless Alarm Interconnect PCA must have a unique Modbus™
address to be recognized on the network. The alarm station address must be in the range of 0x80-0x8F. The
dial on the PCA sets the last digit (LSD) of the address, the first digit of the address is fixed at ‘8’ hex. The
Modbus™ address of the Interconnect PCA is utilized for monitoring the Battery.
1.1 Strobe
The alarm station warning light is configured with choice of dome colors such as amber, blue, clear, green,
magenta, or red. Dome guard is included. The rugged warning light is specifically designed for hazardous
locations or corrosive environments where a very bright visual signal is required.
Figure 3 Strobe
1.2 Horn
This range of light weight all GRP, explosion proof sounders has been designed with high ingress protection to
cope with the harsh environmental conditions found offshore and onshore in the oil, gas and petrochemical
industries. The Horn is capable of producing up to 125dB @ 1m output dependent upon the tone settings
(refer to the “Sound Signals” Table).

1.3 Smart Battery Pack
The A2V1-DV2 and V2-DV2 Alarm Stations are powered by a battery pack that enables it to be remotely
mounted without the need for external cabling.
Figure 5 Battery Pack
The 12V 2900mAh Smart Battery Pack (Teledyne Detcon’s part number 976-0BP303-290) consists of
rechargeable Lithium-Ion batteries and is equipped with integrated safety electronics that include a fuel gauge,
voltage monitor, and 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 packs are designed to plug into an 8-pin Beau connector on the Terminal Board that the
sensor is connected to. The battery Pack and Terminal Board are housed and sealed in Teledyne Detcon’s Class
I Div 1 Aluminum Condulet to protect them from exposure to outside elements. Operating periods before
recharge will vary based on alarm usage but can be as long as 5 months for the 12V 2900mAh battery pack.
Improper use of the battery pack may be hazardous to personnel or the environment and will void the warranty.
1.4 Quad Battery Charger (Optional)
Detcon’s Smart Battery Pack can be charged as needed using Detcon’s optional Quad Battery Charger which
can charge up to four battery packs at one time. The Quad Battery Charger comes with a plug-in AC/DC adapter
that plugs into a standard 120VAC outlet for power. The DC end of the adapter plugs into the DC power jack
of the charger providing 24VDC. The Quad Battery Charger has four charging ports, each with 8-pin Beau
connectors for battery pack connection. The ports and connectors are keyed to prevent incorrect positioning and
connection. Each port has its own “FAULT” LED indicator and “CHARGE” LED indicator and will display
either a red light or green light depending on the status of each battery being charged. Charging times will vary
depending on the charge state of each battery pack, but a full charge of a depleted battery pack can take up to 24
hours.

SW-A2V2-DV2
SW-A2V2-DV2 Instruction Manual Rev. 1.4 Page 4 of 11
Figure 6 Quad Battery Charger
When first powered on and with no battery packs connected to the charger, all the LED indicators on the Quad
Charger should be green. When a battery pack is seated into a charging port, the “CHARGE” LED will go from
green to red indicating the battery pack is not sufficiently charged. Once fully charged, the LED will go from
red to green and the battery pack is ready to be used.
The “Fault” LED should remain green indicating that there are no problems with the battery pack or charging
port. If the “Fault” LED turns red with the battery pack connected, then there is a problem or issue with the
battery pack and it should not be used and be removed immediately. If the “Fault” LED turns red without a
battery pack connected to the charge port, then there is a problem or issue with the port and that port should no
longer be used.
Battery packs can remain connected to the charger even after a full charge indication (Green “Charge” LED) is
shown due to the protection circuitry of the batter pack which prevents any overcharging issues.
1.5 RXT Wireless Transceiver
The wireless function of the alarm station is made possible by Teledyne Detcon’s RXT series wireless
transceivers. These transceivers transmit signal data such as analog 4-20mA DC or serial Modbus™ and can
support up to 32 devices. They operate at 2.4GHz and conform to non-licensed radio frequency appliance usage
around the world. Wireless network integrity and security is accomplished using direct sequence spread
spectrum wireless mesh technology. Wireless applications can be as simple as a single field device
communicating with a host controller or any number of field devices forming a network of subscribers. Every
device in the network is capable of functioning as a router and repeater for all other devices in the network. This
means that subscribers can “hop” through neighboring devices to communicate with each other thereby widening
network access points. This unique and innovative technology is designed to create a robust network that
automatically routes around congestion and line-of-sight obstacles while improving throughput as subscriber
device density increases.
Refer to the RXT-320 manual for more detailed information.

2.0 Installation
NOTE: The wireless alarm station is a precision instrument and care should be taken when handling it.
The Wireless A2V2-DV2 Alarm Station is made to be mounted on a 2” or 3” diameter pipe. Two 3” U-bolts
with hardware are provided for mounting. The location for mounting the wireless alarm station should be
carefully selected. Occasional access to the unit will be necessary for battery replacement and maintenance.
The unit should be properly grounded according to local electrical codes and specifications. No other wiring is
necessary for these units, once the unit has been mounted, install the battery pack and the unit will begin normal
operation.
Figure 7 Dimensional
With the RXT-320 Transceiver, the Address Switch on the Wireless Interconnect PCA should be set to the
correct address for the alarm station. This switch is normally set at the factory. Each Wireless Alarm
Interconnect PCA must have a unique Modbus™ address to be recognized on the network. The alarm station
address must be in the range of 0x80-0x8F. The dial on the PCA sets the last digit (LSD) of the address, the
first digit of the address is fixed at ‘8’ hex. The Modbus™ address of the Interconnect PCA is utilized for
monitoring the Battery. For more information refer to the RXT-320 manual.
The A2V2 utilizes two batteries. Both batteries must be the same type. To install the battery packs, insure that
the area is de-classified. Remove the cover from the junction boxes. Remove the Battery Cap and install a
battery in each junction box. The batteries can only be installed one way, and orientation is mandated by the
battery supports and the connector. Insure that the batteries are completely seated and close the retaining lever
over the battery until it latches. The unit will power up and begin normal operation. Replace the cover on the
junction Boxes and insure that the covers are completely screwed down and secured by the cap-head screw.
