Fast Stable Communication

Built-in intelligence means less information needs to be sent between the device and the Signature Loop Controller. Other than routine supervisory polling responses, Signature devices only need to communicate with the controller when they have something new to report. This provides very fast control panel response and allows a lower baud rate (speed) to be used for communication on the circuit. The lower baud rate offers several advantages including:

• Less sensitivity to circuit wire characteristics
• Less sensitivity to noise glitches on the cable
• Less emitted noise from the analogue wiring
• Twisted or shielded wiring is not required

Testing & Maintenance

Automatic self-diagnosis identifies when a Signature device is defective and issues a trouble message. The user friendly maintenance program shows the current state of each device and other pertinent information. Single devices may be turned off temporarily, directly from the control panel.

True multisensor technology means that a single device can perform optimally under a wider range of conditions than any singlesensor detector.
