External Audible and Visual Alarms
In large warehouse, noisy workshop and unattended area, DSR’s built-in buzzer alarm is not loud enough. So an external audible and visual alarm device is needed as to attract attention on any over-limit conditions. When there’s over-limit from the test environment, the external audible and visual alarm will automatically start; so admins can take in time actions when receive the alarm. We have two ways of alarm: wired alarm and wireless alarm.
