Kentec Sigma XT Ancillary PCB

SKU: Sigma-XT-Ancillary-PCB
SKU: Sigma-XT-Ancillary-PCB Category: Brand:

Summary

<p>The Kentec K03000M2 Sigma XT Ancillary PCB is a sophisticated 24V DC powered expansion unit designed to extend the control capabilities of Sigma XT fire suppression systems. Compatible with all Sigma XT control panels operating software version SIGXT_11A.HEX or above, this professional-grade ancillary board provides volt-free normally open contacts for controlling subsystems and plant equipment remotely from the main control panel over an efficient two-wire data bus.</p>

<p>Unlike mains-powered variants, the K03000M2 requires a 20-30V DC power supply, necessitating additional power cores either from the main control panel or from another suitable 24V DC source. This DC-powered design makes it particularly suitable for installations where mains power distribution is impractical or where integration with existing low-voltage fire safety systems is preferred, whilst maintaining full functionality and system integration capabilities.</p>

<p>The scalable architecture supports up to 7 ancillary boards per control panel, each individually addressed using a binary coded DIL switch system. With relay-operated LED indicators providing clear visual status confirmation and a maximum total cable run of 1200 metres, the K03000M2 offers exceptional flexibility for complex installations whilst delivering reliable remote control functionality across extensive fire protection networks.</p>

FAQ

How does the K03000M2 differ from the K03750M2?

The K03000M2 operates on 20-30V DC power and requires additional power cores from the main panel or another 24V DC source, whereas the K03750M2 is mains powered (230V AC) with an integral PSU requiring only a two-core data cable.

What power supply options are available for the K03000M2?

The K03000M2 can be powered from the main control panel’s 24V supply or from another suitable 24V DC source, providing flexibility for installations where mains power distribution is impractical or where integration with existing low-voltage systems is preferred.

How many K03000M2 units can be connected to one system?

Up to 7 ancillary boards can be connected to a single Sigma XT control panel, with each unit individually addressed from 1 to 7 using a binary coded DIL switch. This can be combined with up to 7 status units on the same serial bus.

What is the maximum cable distance for installation?

The total length of the data cable from the main control panel to the last ancillary board must not exceed 1200 metres, providing excellent coverage for large installations across extensive sites.

Which control panels are compatible with the K03000M2?

The K03000M2 is compatible with all Sigma XT control panels that have operating software version SIGXT_11A.HEX or above, ensuring seamless integration with current and future system configurations.

What type of outputs does the unit provide?

The unit provides volt-free normally open relay contacts rated at 30V DC 1 Amp, allowing reliable control of subsystems, plant equipment, and building services remotely from the main fire suppression control panel.
