Importance of Communication and Equipment Checks

Effective communication is crucial in the security sector. Strong communication helps protect property and supplies against theft and security breaches, and it makes it easier to protect the public, employees, and team members.
Before use, you must check that the communication system is fully operational by:
- Performing radio checks to ensure the radio is in good working order.
- Confirming the power is on and the battery is charged.
- Maintaining a volume that allows you to hear calls.
- Checking the radio frequency to verify it’s working and still within signal range.
Radio equipment often includes features like safety and durability, lone worker and personal calling, and long battery life.
Communication Channels and Protocols
Security personnel use radio communication channels to interact quickly and effectively, enabling the prompt activation of a safety alert message for the entire crew in dangerous circumstances. They also use these channels to coordinate with other team members and issue security alerts.
Channels used in the security industry include:

- Two–way radio.
- Transceiver.
- Cell phone.
To convey security risk information, you must use appropriate language, protocols and codes, and follow standard operating procedures.
Security risks that may need reporting include:
- Assault or harm.
- Break-in or burglary.
- Pilferage.
- Deliberate or accidental damage.
Communication Codes
Keywords used to convey certain messages in the security industry include:
- ROGER: Means the message is understood.
- OVER: Indicates the call sign has been transmitted and you are awaiting a reply.
- OUT: Indicates the call sign is finished transmitting at this time.
The Phonetic Alphabet
The international phonetic alphabet (spelling alphabet) is a vital verbal tool for transmitting information clearly, especially during noisy disturbances. Using it to spell a name or address eliminates the chance that the listener won’t hear or understand what was said.
Receiving and Answering Communications
You must receive and answer incoming communications promptly using clear and concise language and following standard operating procedures.
Clear and concise communication involves:
- Choosing your words carefully and exactly.
- Structuring your sentences to remove unnecessary words.
- Correctly applying grammar.
Effective communication also helps maintain healthy working relationships with coworkers and superiors by encouraging clarification and proper channel use.
Steps to receive and answer incoming communications include:
- Plan what you want to say.
- Be mindful of over-explaining.
- Use a specific example.
