Transparent Input Action

One of the choices available to you in the input programming of a device is the setting ‘transparent’.  Setting a device as transparent will have no effect at all on the panel. If in fact the input device is to trip the panel will remain in a quiescent state. 

The primary usage for this type of an input would be the activation of an output relay or output device based upon the transparent input.  A cause and effect can easily be set-up which will allow the transparent input to activate an output device or devices without the panel indicating any activity.

If you are to encounter the need for an output function which has no effect on other panel functions, this is a superior method to consider.

Internal NAC Synchronization and RS Panels

VES “RS series” Fire Alarm Control Panels are capable of strobe synchronization without additional hardware or software.The synchronization function can be activated on either NAC channel (or both) and supports Wheelock, Gentex, System Senor and Amseco families of strobes (see our manual for exact models). 

Our synchronization capabilities allow you to program the horn / strobes in one of two methods. 

When the alarm silence button is activated:

When the strobe silence option is not selected:

  • The horns will cease and the strobes will continue to activate.

    • Resound will restart the process

When the strobe silence option is selected:

  • Both the horns and strobes will cease.

    • Resound will restart the process

Set-up of this capability is easy and straightforward.  The options may be selected through VES Discovery On-Line programming, Loop Explorer PC programming or through the soft keys of the RS panel.
