Section 2-1- Description
General
The Dual-Circuit SAFEPATH
®
Panel is a stand alone, single or dual channel supervised audio fire
and emergency evacuation system. Figure 2-1 on Page 2-2 illustrates the basic capabilities of the
Dual-Circuit SAFEPATH
®
panel.
The control panel that activates the Dual-Circuit SAFEPATH
®
Panel can range from simple push
buttons to a sophisticated computer based control panel providing dry contact closures.
The Dual-Circuit SAFEPATH

Panel does not sense an emergency condition or hazards such as fire;
it is only a part of a system that does sense such conditions. The Dual-Circuit SAFEPATH
®
Panel,
when activated, provides a pre-recorded tone and/or voice message(s) to notification appliances.
When used as part of a protective signaling system, the Dual-Circuit SAFEPATH
®
Panel must be
properly connected to a compatible control panel that has been approved by a nationally recognized
testing laboratory. The SAFEPATH
®
Panel has been tested, approved and LISTED by the
Underwriter Laboratories (UL) and is compatible with LISTED control panels and notification
appliances for proper operation.
THE DUAL-CIRCUIT SAFEPATH
®
PANEL MUST BE PROPERLY INSTALLED, PROGRAMMED,
AND CONNECTED TO A COMPATIBLE FIRE ALARM CONTROL PANEL TO FUNCTION AS A
VOICE EVACUATION SYSTEM.
