What types of alarms does the M4 JCAD issue upon detecting chemical agents?

The M4 Joint Chemical Agent Detector (JCAD) is designed to provide immediate alerts to users when it detects the presence of chemical agents. The correct response highlights that the M4 JCAD issues both visual and audible alarms.

The visual alarm typically includes lights that may flash or change color to indicate detection, ensuring that the user can see the alert even in low-light conditions. The audible alarm generates sound signals that provide a clear indication of detection, which is crucial for alerting personnel in environments where visual cues may not be as easily noticed, or for those who may be focused on other tasks.

This combination of alerts enhances situational awareness for operators, allowing for swift and effective response actions. The device's design emphasizes the importance of ensuring that personnel can detect threats quickly and respond appropriately to mitigate risks associated with chemical agents. This capability is essential in maintaining the safety and effectiveness of reconnaissance operations in a CBRN environment.
