Kentec Sigma XT+ Extinguishant Coincidence Unit
£447.76 (inc VAT: £537.31)
Summary
The Kentec Sigma XT+ Extinguishant Coincidence Unit (ECU) is a sophisticated fire suppression control system designed to provide EN12094-1, EN54-2 and EN54-4 compliant extinguishant control. Featuring two fully monitored inputs for connection to fire detection control equipment or addressable control modules, this versatile unit delivers comprehensive control capabilities for all extinguishing applications.
With its extensive range of programmable features and inputs/outputs, the Sigma XT+ ECU offers exceptional flexibility for system designers and installers. The unit incorporates dual extinguishant outputs that can be configured for main/reserve applications, ensuring maximum reliability and system redundancy. A built-in countdown timer displays the time until discharge in seconds, providing clear visual indication during critical sequences.
The system supports serially connected status units for reduced wiring costs and simplified installation, while offering up to 512 programmable input/output capabilities via optional plug-in expansion cards. Each unit is independently configurable through a simple code-based programming interface, making it suitable for a wide range of fire suppression applications where a fully featured control device is required.

FAQ
What fire detection systems is the Sigma XT+ compatible with?
The Sigma XT+ features two fully monitored inputs that can connect to fire detection control equipment or addressable control modules, making it compatible with most conventional and addressable fire detection systems.
How does the main/reserve facility work?
The dual extinguishant outputs can be configured for main/reserve applications, providing system redundancy. If the primary extinguishant system fails, the reserve system automatically activates to ensure continuous protection.
What is the maximum number of inputs and outputs available?
The base unit provides 3 programmable inputs and 5 programmable relay outputs. With optional plug-in expansion cards connected serially, the system can support up to 512 programmable input/output points.
How is the countdown timer displayed?
The system features an 8-line, 40-character graphic LCD display that shows the discharge countdown timer in seconds, providing clear visual indication of the time remaining until extinguishant release.
What power supply and battery backup options are available?
The unit operates on 230V AC or 110V AC mains supply (link selectable) with a 24V DC, 5.25A power supply. Battery backup supports up to 2 x 7Ah sealed lead acid batteries with temperature compensated charging.
Can multiple status indicators be connected?
Yes, the system supports serially connected status indicators via RS485 communication, reducing wiring costs and installation complexity whilst allowing comprehensive system monitoring across multiple locations.
