SW-AV2-DV2

1.0 Description

The Detcon AV2-DV2 Alarm Stations are wireless, battery powered alarm stations with a two 5 Joule Strobes
and an 110Db @ 1mtr Horn that can provide one of 16 possible alarm tones. The unit is designed for
installation and use in Hazardous duty, corrosive work environments rated at Class 1, Division 2, Groups E, F,
and G.

Figure 1 Basic C1D2 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 12V battery
packs. Communication is performed via the Detcon RXT-300 or RXT-320 series of transceivers. Access to
the unit is only necessary for battery maintenance or exchange. With the addition of a solar panel, access can
be kept to periodic functional tests and checks.

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-AV2-DV2

If the unit utilizes the RXT-320 Transceiver, the rotary switch on each of the Wireless Alarm Interconnect
PCA’s 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. This switch is not used with the RXT-300
Transceivers.

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

The alarm station vibrating horn produces a noise level of a 100dB of sound by the electromechanical
vibration of a stainless steel diaphragm. The horn mechanism has an effective broadcast range of 200 feet.
The horn is enclosed in heavy-duty copper-free cast aluminum housing tapped for 3/4 - inch conduit.

The horn is capable of producing coded blasts or sustained tones, and is excellent for general alarm,
start/dismissal, coded paging, and process control signaling in areas where their sound output exceeds ambient
noise levels. The horn in the Strobe/Horn alarm stations has 32 possible combinations of sounds that are
selectable by switch settings inside the alarm.

1.3 Smart Battery Pack

NOTE:

SW-AV2-DV2

Figure 5 Smart Battery Pack

The Wireless Alarm Station assembly also comes with a battery pack that allows the assembly to be remotely
mounted without the need for any cables because of its wireless operation. Detcon has several options for
battery packs. The battery packs provided are Detcon’s plug-in Smart Battery Packs which provides an output
of 12VDC (See Figure 5). The battery packs consist of rechargeable Lithium-Ion batteries and are 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. The battery packs are designed to plug onto an 8-pin Beau connector
on the 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 for the Wireless DM-100 assembly 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.

The Wireless Alarm Station can also be powered by a customer provided external DC

power source. Refer to Section 2 for more details.

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 8­pin 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-AV2-DV2 Instruction Manual Rev. 0.3 Page 3 of 8

SW-AV2-DV2

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 Series Wireless Transceivers

The wireless function of the alarm station is made possible by 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.

Detcon offers two models of the wireless transceiver, Model RXT-300 and Model RXT-320. Both models are
functionally similar with one major difference: the RXT-300 provides a network wide control processing
capability, whereas the RXT-320 does not. Refer to each models instruction 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 AV2-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.

No wiring is necessary for these units, once the unit has been mounted, install the battery pack and the unit
will begin normal operation.

If the unit is equipped 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. If there is
more than one alarm station, each station should have a unique address for proper operation. For more
information refer to the RXT-320 manual. Units equipped with RXT-300 Transceiver do not use this switch

The AV2 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.

Battery operation can be supplemented by the addition of an external 24VDC power source. The unit should
not need the addition of an external 24VDC power source, but if an external 24VDC is to be added, J6 is

3.0 Operation

The AV2-DV2 Wireless Alarm Stations provide two strobes and a dual alarm horn. The wireless alarm station
is set to respond to alarms from the controlling unit. The controller/wireless network has independent control
over the strobes and the Horns, and they will be activated when the appropriate alarm is activated.

All strobes have a flash rate of 1 Hz (one flash per second). This is preset by the manufacture and cannot be
modified.

The horn has up to 32 possible settings, for use in different configurations. The default settings of the horn are
factory set. To change the setting of the horn, remove the rear end of the horn, and set dip switches according
to the Sound Signals Table.
