1.0 Description

The Detcon A1-DV2 Alarm Station are special battery powered alarm stations with a 110Db @ 1mtr Horn. . 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. The unit utilizes a customer provided contact closure to activate the alarm.

The alarm station is powered by its internal 12V battery pack. Activation of the alarm is dependant on customer provided contact closure. This external contact closure provides the completed circuit needed for the alarm unit to operate. 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.

Power to the unit is provided by a 12VDC Battery Pack, the Wireless Alarm Interconnect PCA, and a DPDT Relay. When an alarm is triggered, the customer provided contact closure will provide a completed circuit for the unit which will then energize the relay and enable the horn.

1.1 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 16 possible combinations of sounds that are selectable by switch settings inside the alarm.

Figure 2 Horn

Horn only units provide one unique tone for each alarm level. The tone settings for these units are set at the Detcon factory and cannot be changed by the user. These alarm tones can be initiated individually, but if both alarms are active, the tone for alarm two has priority.

1.2 Smart Battery Pack

A1-DV2

Figure 3 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 3). 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 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.

NOTE: The unit will not function if the battery pack is weak or discharged. The Battery pack should be checked periodically, and charged or changed as needed.

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)

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 4 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.

2.0 Installation

NOTE: The alarm station is a precision instrument and care should be taken when handling it.

The Wireless A1-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.

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. Insure that the battery is completely seated, and close the retaining lever over the battery until it latches. If properly wired, the unit will begin normal operation. Replace the cover on the junction Box, and insure that the cover is completely screwed down and secured by the cap-head screw.

NOTE: A weak or discharged battery pack will cause the unit to become non functional. The Battery pack should be checked periodically, and charged or changed as needed.

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 1). This voltage will be used to charge the battery pack as well as aid in operation of the alarm station.

3.0 Operation

The A1-DV2 Alarm Station provides a single horn. The alarm station is set to respond to dry contact closure, provided by the customer. When Contact closure is detected by the alarm station the horn is activated. The alarm station operates on a 12VDC Battery Pack; no further power is required for proper operation. The unit is dormant until contact closure is provided. When contact closure is detected, the alarm station becomes active, and power is applied to the horn.

The Battery Pack should be checked periodically, and charged or changed as needed. The alarm station should also be tested periodically to ensure proper operation.

The horn has up to 16 possible settings, for use in different configurations. The default settings of the horn are factory set. The default setting for the horn is B(11). To change the setting of the horn, remove the rear end of the horn, and set the rotary switch (SW1) according to the Sound Signals Table. SW1 in the horn is a 16 position rotary switch and is used to set the horn sound signal.
