Duress systems drastically reduce the notification and response time in the event of a hold-up in a bank, a theft in a jewelry store or a hospital room emergency, for example.

They can be wireless, monitored via central station (phone-line dialing), onsite paging via SMS or pager, or monitored by onsite security personnel. The purpose of a duress system is to provide convenient and efficient notification of an emergency. IFSS relies on reputable manufacturers of duress systems that include Honeywell, LENEL, NAPCO, DMP (Digital Monitoring Products), Bosch, and DSC.
