It can be configured to dial out to up to 10 message recipients (10 phone numbers), each in one of three escalating priority groups. This allows messages to be sent to a selected group of recipients, and if not acknowledged within a set time, then sent to the second group of recipients, and if still not acknowledged, then sent to the third group of recipients.
The Silent Sentry is easily configurable by the user, using the free Omniset configuration software. Using Omniset PRO software, it can even be configured remotely over the GSM network. The Silent Sentry can be connected to any existing alarm annunciator system and can also be used to remotely acknowledge alarms using a mobile phone.
