Man Down

Man Down on CALM Systems

The Chatterbox Alarm Location Monitoring (CALM) Man Down feature works using two-way digital radios that have an inbuilt mercury switch. If the radio remains horizontal for a period of time defined by the customer, for example 30 seconds, it triggers an alert. If the worker doesn’t respond to this alert within another 30 seconds an alarm is automatically sent. The alarm can be received by a central control centre, where the location of workers can also be monitored, or by another two-way radio.

In this way, should a member of staff have a fall, become unconscious or suffer an attack that has incapacitated them, help can be dispatched immediately. If the system has been commissioned with a tracking system too then the workers location can be readily identified.

CALM’s Man Down feature can track workers using beacons or GPS depending on the customer’s requirement.

If you are concerned with lone worker safety you may also want to consider CALM’s Lone Worker feature and look at our CALM Personal SOS Button, which is ideal for workers who do not need to carry a two-way radio but still require protection.
