JamAlert Cellular Detection Module

The JamAlert module is a cellular frequency interference detector. The module has two integrated outputs that can be connected to zones of the panel or used to activate peripheral devices. For more information on zone programming, consult the compatible panel's installation guide. The JamAlert also features an LED that illuminates when interference is detected and includes a test mode to ensure the module correctly detects frequencies.

• One JamAlert cellular detection module
• Two 1 KΩ EOL resistors
• Four mounting screws

The module can be powered from the control panel's 12 VCC auxiliary output. Observe polarity and use an 18-22 AWG wire to connect the module's +12 terminal (positive) to the panel's +12 terminal, and the module's -12 terminal (negative) to the panel's -12 terminal. Refer to Figures 2 and 3.

The JamAlert module includes tamper protection for both the wall and the housing. The housing tamper is activated when the module cover is secured to the enclosure. The wall tamper is activated when the back of the cover is mounted to a wall. Removing the cover or dismounting the module from the wall sends a tamper message to the monitoring center.

Install the module away from metallic objects and at least 1.2 to 1.5 meters (4 to 5 feet) from any device that emits high RF frequency, including high-power wireless receivers, Wi-Fi routers, and cellular signal amplifiers, to ensure correct frequency detection. Do not mount the module in or on a metal control panel enclosure. Mounting the module on or near metallic surfaces affects performance in detecting cellular interference.

The module should be mounted to a wall using the included #6 screws in the mounting holes. Refer to Figure 2. Mount the module in a secure, dry location to protect it from damage caused by tampering or environmental factors. It is not necessary to remove the PCB when installing the module.

CAUTION: Disconnect all panel power before wiring the module. Failure to do so may cause damage to the equipment or injury. Observe polarity when making power connections.

Use 18 to 22 gauge wire when wiring the module. When routing wires, ensure they do not interfere with the tamper switch. Refer to Figures 3 and 4.

1. Use a wire to connect the module's 12 V positive terminal to panel terminal 7. Use another wire to connect the module's 12 V negative terminal to DMP panel terminal 10.
   Note: If connecting to a non-DMP panel, confirm the correct terminals for positive and negative 12 V.
2. For the cellular interference detection output, use a wire to connect the normally open (NO) terminal to any panel zone. Use another wire to connect the common (C) terminal to panel ground.
   Note: If connecting to a DMP panel, use a 1 KΩ resistor between the NO and C terminals. If connecting to a non-DMP panel, use the correct resistor value for that panel.
3. For the tamper output, use a wire to connect the C terminal to any panel zone. Use another wire to connect the NC terminal to panel ground. Place a 1 kΩ resistor in the wire connected to the NC terminal.

1. Place the antenna onto the SMA connector. Refer to Figure 2.
2. Turn the antenna until it is firmly snug.
3. Carefully replace the cabinet cover onto the mounted base. Ensure that no PCB components are damaged when removing or replacing the cabinet cover.

Refer to the compatible panel's programming guide for complete programming information. After completing each step, press CMD to advance to the next prompt. To program the JamAlert on a DMP panel, complete the following steps:

1. Reboot the panel. On a keypad, enter 6653 (PROG) to access the PROGRAMMING menu.
2. In ZONE INFORMATION, enter the zone number for the cellular interference detection output.
3. In *UNUSED*, enter a name for the zone.
4. In ZONE TYPE:, select the zone type.
5. In NEXT ZN?, select YES.
6. Enter the zone number for the tamper output.
7. In *UNUSED*, enter a name for the zone.
8. In ZONE TYPE:, select the zone type.
9. Press CMD until the END option appears. Then press a top row select key or area to save the programming.

When cellular frequency jamming is detected, the built-in output activates and sends an alarm to the panel. Additionally, if cellular jamming is detected, the LED turns red. If the module has power, the LED turns green.

JamAlert uses local test operation to ensure the module correctly detects frequencies. To enter test mode, follow these steps:

1. Ensure the JamAlert is within its housing and that the rear tamper switch is depressed.
2. Disconnect the antenna and then power up the JamAlert.
3. Press the tamper button at least 4 times quickly to enter test mode.
4. Connect the antenna to automatically activate detection mode. When the device detects a frequency, the LED lights up.
5. To exit test mode, reboot the device or press and hold the tamper button for more than 5 seconds. The LED will flash green 3 times to confirm exit from test mode.
