VESDA Multi-function Card

The VESDA Multi-function Control Card (MCC) is an interface card for the range of VESDA LaserFOCUS™ (VLF) smoke detectors. An MCC expands the range of input and output communications a VESDA LaserFOCUS can perform.

Why use a Multi-function Control Card?

Installing a Multi-function Control Card into a LaserFOCUS detector provides a cost-effective solution for customers who need enhanced connectivity, fault detection and monitoring, and annunciation of alarms and faults. The principal benefits include:

Improved FACP connectivity

The VLF is fitted with two (2) alarm relays in its standard form. With an extra two (2) relays, the Multi-function Control Card allows reporting of all four (4) alarm levels on dry relay outputs.

Enhanced annunciation

An MPO (Monitored 24 V Powered Output) is available on the VIC-030 version of the card. The MPO provides power to devices such as sirens or strobes, and monitors the line integrity.

Enhanced control and fault detection

With the Multi-function Control Card installed, a VLF has two (2) General Purpose Inputs (GPIs), allowing, for example, one GPI to report on loss of mains power and the other GPI to be used as a reset input.

The VIC-030 version of the card has a self-configuring GPI, depending on the jumper selection for MPO/Relay3. If MPO is selected, activation of the GPI will disable the MPO. If Relay3 is selected, the GPI will be set to External Fault (e.g. for mains power supply monitoring).
