Bard BG1000 Anti-Theft System
Product Information
The Bard Guard BG1000 Anti-Theft System is designed to prevent coil theft from Bard commercial HVAC systems. This comprehensive system utilizes both mechanical and electronic methods to deter theft and notify the owner of any unauthorized entry into the unit. It is an optional feature available for FUSION-TEC wall-mount units. The anti-theft system consists of a large interlocking metal frame that encloses the unit’s front access panels, along with a series of switches connected to a control box. If an attempt is made to steal a coil, an alarm will sound, and a signal will be sent to a remote network operating center.
The system includes four plunger switches and a pressure switch that monitor the state of the air conditioner. If there are changes in the system’s pressures or if the panels are opened, indicating an attempt to remove the coil assemblies, an 80db audio alarm will sound through a speaker on the unit. Additionally, a signal will be sent to a remote network operating center via the LV1000 controller.

Description
The purpose of the Bard Guard anti-theft system is to deter coil theft from Bard commercial HVAC systems. The comprehensive system includes both mechanical and electronic methods for deterring theft and notifying owner upon unauthorized unit entry. The Bard Guard anti-theft system is optional on the FUSION-TEC wall-mount units. The anti-theft system consists of a large interlocking metal frame that encapsulates the unit front access panels and a series of switches wired to a control box. When an attempt is made to steal a coil, an alarm is sounded and a signal sent to a remote network operating center.
The external mounted security frame is both for cabinet security and visual deterrent. The frame is assembled with four 2″ x 2″ x 1/8″ angles that each independently hinge away from the front of the unit. The hinges are internal to the frame angles to prevent tampering and each frame has four captivated security fasteners to prevent attempts at cutting the fastener or removal without the required tool. The security key used for removing the fasteners is shipped in a plastic bag with the unit. The four angles are also interlocked to each other, requiring the four security fasteners be completely removed prior to internal unit access by an authorized technician. The frame is designed to remain attached to the unit at all times for safety and ease of use. The four plunger switches and the pressure switch monitor the state of the air conditioner. Should the system’s pressures change or panels open, indicating an attempt to remove one or both of the coil assemblies from the air conditioner, an alarm will sound through an 80db audio speaker on the unit (a pre-recorded audible warning in English and Spanish) and a signal is sent to a remote network operating center via the LV1000 controller.
Installation
WARNING: Electric shock hazard.
- Disconnect VAC and VDC power supplies before servicing.
- Failure to do so could result in electric shock or death.

Refer to the National Electrical Code (NEC) for complete current carrying capacity data on the various insulation grades of wiring material. All wiring must conform to NEC and all local codes.
IMPORTANT: When working with circuit board components, Bard recommends the use of an anti-static wrist strap to prevent static electricity shorts to electronic controls.
Mounting the BG1000 Controller
The controller can be installed anywhere inside the shelter that is suitable, preferably at eye level and near the LV1000 controller. The dimensions of the BG1000 controller are 5-1/2″ x 11-1/2″ x 3″. Four mounting holes are provided for mounting to the wall and holes for conduit connection are provided in the base and sides of the controller. Use #12 screws to secure the controller in its intended location. Conduit is recommended for all wiring.
The BG1000 controller includes a fused power supply terminal in the terminal block. Before connecting wires to the terminal block, confirm that the fuse in the fuse holder is in the proper position (active) as shown in Figure 1. The BG1000 controller is not weatherproof and is intended for use inside weathertight structures only.
Connecting Wall-Mount Units to BG1000 Controller
The wall-mount unit front panel plunger switches and pressure switch are wired in series and terminated at terminals 7 and 8 on a terminal block inside the control panel of the wall-mount unit. The speaker wires are also terminated on the terminal block at terminals 5 and 6. Run a total of four wires (two for the switches and two for the speaker) from the wall-mount unit terminal block to the Bard Guard controller in the shelter. Up to four units can be connected to a single BG1000. The system is limited to using two speakers.
Use 18 gauge shielded cable to connect the switches and speakers (via terminal block) to the BG1000 controller. The BG1000 wires can be run through the same conduit as the FUSION-TEC unit communication wires. Refer to Figure 2 and Table 1 for terminal block reference and connection points from the wall-mount unit to the BG1000 and the BG1000 to the LV1000 controller.
- Terminals 1-8 are switch connections (from FUSION-TEC unit)
- Terminals 9-10 are relay contacts for remote notification (to LV controller)
- Terminals 12-13 (polarity sensitive) are -48VDC power (to LV controller)
- Terminals 14-15 are speaker connections (from FUSION-TEC unit)
Connecting BG1000 Controller to LV1000
The BG1000 controller needs to be connected to the LV1000 controller to receive power and send remote alarm notification. The BG1000 power supply wires and remote notification wires can be run through the same conduit.
NOTE: CMA-36 BG1000 Power Supply Kit (optional) is available as an alternate method for powering the Bard Guard Anti-Theft System, providing power to the BG1000 controller through a 110V/120V wall outlet. If -48VDC power is not available at the site, CMA-36 is required. See Bard supplemental manual 7960-802 for more information.

should be minimum 16 gauge, maximum 14 gauge. These connections are polarity sensitive. Run wiring from BG1000 terminals 12 (+) and 13 (–) to LV1000 terminals 1 (+) and 2 (–) as shown in Figure 3. Although a blocking diode is in place to protect the system, it is very important that the supply wiring is installed properly. A reliable earth ground must be connected in addition to any grounding from conduit. Grounding bolts and nuts are supplied with the BG1000. Use the bolts and nuts with a field-supplied grounding lug to connect ground.
Remote Notification Communication Wiring
The LV will indicate an anti-theft alarm when the BG1000 controller indicates an alarm to the anti-theft input on the LV. This alarm will open an alarm relay output to the remote network operating center for remote notification. Connect BG1000 terminals 9 and 10 to LV1000 terminals 14 and 15 using 18 gauge shielded cable as shown in Figure 3. When the input no longer indicates a theft, the alarm will automatically clear and the alarm relay will return to its normal state.
Enabling Anti-Theft in LV1000
In order to operate properly, the Bard Guard anti-theft system must be enabled in the LV1000 controller. Refer to Anti-Theft Alarm in the latest version of LV1000 Service Instructions manual 2100-673 for information on enabling the anti-theft in the LV and changing direction of the alarm input and output (if required). At this stage, the installation of the BG1000 controller is complete.
Operation
Arming System
When the system powers up for the first time, it arms automatically. Once all sensors are satisfied (circuit closed), a red indicator light will be illuminated on the front of the BG1000 controller. If system does not arm when first powered, press the DISARM/RESET button once to be sure the red light is on. When the red LED is illuminated, the system is armed. When the sensors are not satisfied (circuit is open), the red LED will turn off and the following will happen:
- An alarm will sound with a prerecorded message. The alarm will continue to sound for up to 10 minutes depending on the preset time (default approximately 2-1/2 minutes—see Figure 5 for information on adjusting alarm time).
- The ALARM function key on the LV1000 controller will be activated. The alarm is acknowledged by pressing the ALARM key. This calls up the antitheftalarm display screen (see Figure 4). When the input no longer indicates a theft, the alarm will automatically clear and the alarm relay will return to its normal state.
- An alarm signal will be sent to the remote network operating center via the LV controller.
The alarm can be reset temporarily at any time while the alarm is sounding by pushing the DISARM/RESET button or closing the circuit. If the alarm has exceeded the time limit, press DISARM/RESET to rearm the system and once again the red LED will be illuminated.
Disarming System
While the system is powered, push the DISARM/RESET button. Once the button is pushed, the blue LED will illuminate. As long as the blue LED is illuminated, the Bard Guard system is disarmed and will remain disarmed depending on the preset time for up to 250 minutes (default approximately 15 minutes—see Figure 5 for information on adjusting disarm time). After the preset time expires, the system will rearm automatically.
For situations that require an individual unit to be disconnected from the Bard Guard security system for an extended period of service time (longer than the maximum 250 minutes disarm time), place a jumper across the appropriate terminals on the BG1000 terminal block to temporarily remove the unit from the security system. Be sure to remove the jumper from the terminals after service has been completed.
