Whether you have a single panel or multiple panels networked together, VES analog Fire Alarm Control Panels allow the devices (Input and Output) to be programmed throughout 500 zones.  Zones may contain one or more devices; devices may be Input or Output regardless of whether they reside on the SLC or the Panel I/O.  Zones become a powerful method for activation of outputs or simply organizing the programming of your system. 

Globally, panels can operate in either common or zonal mode.  When panels are set for zonal mode; inputs and outputs of the same zone will automatically activate when the output properties match those of the input.

When a Cause & Effect scenario is programmed, the utilization of zones for either Input (Cause) or Output (Effect) is an alternative method for administration of the set-up.    

Cause and Effects

VES analog Fire Alarm Control Panels offer flexibility for any type of installation.  A large portion of the panel flexibility is achieved through programmable Cause & Effects.  Cause & Effects are available to users in three different varieties:

  • Actions
  • Disablements
  • Test Mode

In any of the three varieties of Cause & Effects an ‘operator’ is used to confirm the validity of the cause.  In other words, the desired effect will never occur if the cause is not satisfied, causes may be satisfied in one of three ways:

  • OR – Any one input that is part of the cause must activate for the effect(s) to activate.
  • Any Two – Any two inputs that are part of the cause must activate for the effect(s) to activate.
  • AND – All the inputs that are part of the cause must activate for the effect(s) to activate.

Causes and Effects can be either individual points or zones; although there are special rules when using zones (only fire points within the zone are recognized), the architecture allows extreme flexibility.  Either Causes or Effects can span multiple nodes of a network system thereby creating additional flexibility.

Throughout a network, 500 separate Cause & Effects may be defined spanning 2000 Inputs and 2000 Outputs.

Actions, which are the most common Cause & Effect, allow either one or many outputs to trigger as a result of a predefined cause.

Disablements, allow one or many outputs to be placed in a disabled condition as a result of an input (typically a key switch).

Test, allow a zone or combination of zones to be placed into a test condition (silent or audible) as a result of an input.  

Based upon the amount of options available in programming, it certainly is possible to set-up Cause and Effects in multiple manners, ultimately allowing the same results.
