Robbery Alarms are also known as hold-up, duress, ambush or emergency alarms. The system is usually activated by inconspicuous devices, such as a foot rail, money clip, or hidden button. Most systems are silent at the customer’s premises and most have communications capabilities to alert someone off site when the alarm is activated.
A holdup or panic button is designed to generate an alarm signal by the manual activation of a device intended to signal a robbery, holdup or emergency in progress. Depressing the button closes or opens the circuit to indicate an alarm.
Foot rails are floor mounted arched enclosures containing a switching device that operates when a person’s foot is slid along the floor under the arch to make contact with a pivoting bar.
Special type of switch used in hold -up alarms. It is placed in a cash drawer, with the bottom bill of a stack inserted in the switch. The alarm is activated by removing that bill.
