Backward compatibility
• Backward compatible with VESDA VLS
• Identical physical and electrical footprint, pipe
arrangement, wired relays and VESDAnet connectivity
• Replicates VLS signature to maintain compatibility with
existing VLS based interfaces
• Provides access point to entire VESDAnet network with
VSM4
• When placing a newer VES or VEP into an older
VESDAnet:
– Run the VES in VLS mode or the VEP in VLP mode
