SW-AV1-DV1 Instruction Manual iv
SW-AV1-DV1
1.0 Description
The Detcon SW-AV1-DV1 Alarm Stations are wireless, battery powered alarm stations with a 5 Joule Strobe
and an 110Db @ 1mtr Horn. The SW-AV1-DV1 uses a Horn/Strobe Combo Alarm. The units are designed
for installation and use in hazardous duty, corrosive work environments rated at Class 1, Division 1, Groups C
and D.
Figure 1 Basic C1D1 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 cables. The alarm station is powered by an internal 12V battery pack.
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. 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).

If the unit uses the RXT-320 Transceiver, the rotary switch on the Wireless Alarm Interconnect PCA is used to
set the Modbus Address of the alarm unit. If more than one alarm station used in the system, each alarm
station must have a unique address for the alarm station to be recognized on the network properly. This switch
is not used with the RXT-300 Transceivers.
1.1 Strobe/Horn Alarm
Several variations of Smart Wireless alarm stations are available. The strobe-horn combination is used with
the wireless SW1-AV1-DV1 Alarm Station. Two single-strobe units are used with the V2-DV1 Alarm
Station. The Smart Wireless alarm station is also available with a single horn in the SW-A1-DV1 model. All
units are UL listed and CSA certified for Class I, Division 1, Groups C and D; Class II, Division 1, Groups E,
F, and G.
Figure 3 Strobe/Horn Combo
The horn in the alarm stations has 32 possible combinations of sounds that are selectable by switch settings
inside the alarm. Horn only units provided a dual horn capability. Horn one and horn two can be set to
different tones via the switch settings; SW1 is used for horn 1 and SW2 for horn two settings. These horns can
be initiated individually, but if both horns are active, horn two has priority. Refer to Section 3.0 for a list of the
available switch settings.
1.2 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. The battery pack provided is
Detcon’s plug-in Smart Battery Pack which provides an output of 12VDC (See Figure 4). 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. The battery pack is
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 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.

Figure 4 Smart Battery Pack
NOTE:
The Wireless Alarm Station can also be powered by a customer provided external DC
power source. Refer to section 2 for more details.
1.3 Quad Battery Charger (Optional)
SW-AV1-DV1
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.
Figure 5 Quad Battery Charger
SW-AV1-DV1 Instruction Manual Rev. 1.1 Page 3 of 10
SW-AV1-DV1
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.
1.4 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.

No outside 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.
To install the battery pack, insure that the area is de-classified. Remove the cover from the junction box.
Release the battery catch, and install the battery. The battery can only be installed one way, and orientation is
mandated by the battery supports and the connector. Ensure that the battery is 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 Box, and ensure that the cover is completely screwed down and secured by the caphead 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
provided for connection to the 24Volt input (refer to Figure 2). This voltage will be used to charge the battery
pack as well as aid in operation of the alarm station.

3.0 Operation
The Wireless C1D1 Alarm Stations provide a strobe and a horn, two strobes, or a single horn. The wireless
alarm station is set to respond to alarms from the controlling unit. The controller has independent control over
the strobe and the Horn, and they will be activated when the appropriate alarm is activated.
All strobes have a flash rate of 1 Hz, one flash per second. The horn has up to 32 possible settings, for use in
different configurations. The default settings of the horn are factory set. The default setting for the Horn is 21
(SW1 and SW2 set to 01000). To change the setting of the horn, remove the horn side of the alarm enclosure,
and set the dip-switches according to the Sound Signals Table. SW1 and SW2 are used to set the horn sound
signal. SW1 and SW2 should be set the same, to insure the correct sound signal.
