Two-way radios are widely used in industries where quick and reliable communication is critical, such as law enforcement, construction, security, and event management. However, there is always a risk of these radios being lost, stolen, or falling into the wrong hands. To address this, many modern two-way radios come equipped with special remote management functions known as Stun, Kill, and Revive. These features provide a robust method to prevent unauthorized use of the radio, offering enhanced security and control in situations where a device has been compromised.

1. Stun Function: Temporarily Disabling a Lost Radio

The Stun function is typically used when a radio has been lost or temporarily misplaced. By sending a stun signal from a second, authorized radio or a central control unit, the lost radio is remotely disabled. This action inhibits the device from both transmitting and receiving communications, effectively rendering the radio useless to anyone who might find or steal it.

Once a radio is stunned:

  • It cannot transmit any outgoing messages.
  • It cannot receive any incoming messages.
  • It becomes non-operational across all channels and frequencies.

The primary advantage of this feature is that it keeps sensitive communication secure and prevents unauthorized persons from eavesdropping or using the radio to interfere with communication systems.

2. Revive Function: Re-enabling a Disabled Radio

The Revive function allows for the reactivation of a stunned radio once it has been found or retrieved. By sending a revive signal from another authorized device, all normal functions of the radio are restored, allowing it to transmit and receive messages once again.

The revive function is valuable in situations where the radio is recovered after being lost or temporarily misplaced, as it allows the user to bring the device back into full operation without the need for manual intervention or reprogramming.

3. Kill Function: Permanently Disabling a Compromised Radio

The Kill function is more severe than the stun feature and is generally used when a two-way radio is believed to be permanently lost or stolen. When a kill signal is sent to the compromised radio, it completely disables all of its functions, making it permanently inoperable. This ensures that even if the radio is found by an unauthorized person, it cannot be used, tampered with, or reprogrammed without specialized intervention.

Once a radio has been "killed":

  • It is permanently disabled and cannot be reactivated remotely.
  • The radio must undergo hardware reprogramming or servicing to restore functionality.

This feature is particularly important in high-security environments where sensitive information could be at risk if the radio fell into the wrong hands.

Use Cases and Benefits of Stun/Kill/Revive Features

The Stun/Kill/Revive features offer multiple benefits for organizations that rely on two-way radios for critical communications:

  • Enhanced Security: These features help prevent unauthorized individuals from accessing private communications, protecting sensitive information and reducing potential security breaches.
  • Cost Savings: Rather than permanently losing a radio and needing to replace it, the revive function allows devices to be recovered and restored to full functionality.
  • Operational Control: These features give administrators the ability to manage their fleet of radios remotely, providing control over which devices are active and ensuring that compromised devices do not disrupt communication.
  • Situational Adaptability: Whether a radio is lost temporarily or permanently, the appropriate action (stun, kill, or revive) can be taken depending on the situation, offering flexibility in managing communication devices.

How the Stun/Kill/Revive Feature Works

The process of sending stun, kill, or revive signals involves the use of a secondary, authorized device or a central dispatch system. These systems typically communicate with the lost or compromised radio over the air, sending specialized digital commands that the target radio receives and processes.

  • Stun Signal: This is a command that disables the radio's ability to transmit and receive.
  • Revive Signal: A reverse command that restores the radio's normal functions.
  • Kill Signal: A final command that disables the radio's internal systems, requiring hardware reprogramming to reactivate.

These signals are often encrypted to prevent unauthorized users from sending stun, kill, or revive commands, ensuring that only authorized personnel can control the radios.

The Stun/Kill/Revive feature on two-way radios is an essential security tool that helps organizations maintain control over their communication networks, particularly in cases of lost or stolen devices. By offering the ability to remotely disable or re-enable radios, these features safeguard sensitive communications and prevent unauthorized use, ensuring operational continuity and security.

Maximize the Potential of Your Current Radios

Two-way radios are excellent for mobility, but sometimes fixed communication devices are a more reliable choice. With fixed devices, you eliminate the risk of them being misplaced or unavailable when emergency communication is needed most.

Wireless Call Boxes

You can enhance your communication setup with two options: wireless call boxes and base station intercoms. Both can be easily integrated with your existing radios. Just provide us with your radio's frequency and privacy code, and we'll program these devices to work seamlessly with your system. Privacy codes, also known as tone codes, interference eliminator codes, or color codes (depending on the manufacturer), ensure your radio only activates when the correct code is transmitted, preventing unwanted noise.

devices that work with 2-way radios

Wireless Call Boxes - A wireless call box functions as a two-way radio enclosed in a waterproof housing, suitable for indoor and outdoor use, even in wet conditions. Mounted on a wall or surface, they are always ready for communication and can’t be misplaced.

desktop intercom radioDesktop or Wall-Mounted Base Station Intercoms - These intercoms are designed for indoor environments. They can be placed on a desk or mounted on a wall, providing the same functionality as a mobile two-way radio but with the added benefit of always being powered and ready to use.

Other Devices - In addition to two-way radios, various UHF-compatible devices can enhance communication capabilities. One popular option is the Wireless PA receiver, which captures radio transmissions and broadcasts them through an amplified horn speaker for wider coverage. Wireless doorbells and customer service callboxes are also available, further extending the functionality and versatility of two-way radios in various environments. See Related Products below for examples of these devices.
