Kentec Sigma SI Extinguishant Status Indicator
Summary
The Kentec Sigma Si Extinguishant Status Indicators provide comprehensive remote monitoring and control capabilities for the industry-leading Sigma XT extinguishing systems. These sophisticated status units deliver detailed indication of control panel status through high brightness LEDs, ensuring operators can monitor critical fire suppression system conditions from strategic locations throughout protected facilities.
Certified compliant with BS EN12094-1 when used with Sigma XT control equipment, the Sigma Si range offers outstanding reliability and performance for small to medium fixed firefighting installations. The units feature monitored data connections, countdown timers showing time remaining until extinguishant release, and comprehensive status indication covering fire zones, faults, system modes, and release conditions.
Available in multiple configurations ranging from basic 6-lamp status units to advanced 10-lamp units with integrated manual release and mode select capabilities, the Sigma Si range accommodates diverse installation requirements. With both standard IP30 and weatherproof IP65 versions available, these robust units provide flexible deployment options whilst maintaining the high build quality and ease of installation that characterises the entire Sigma XT system family.

FAQ
How many Sigma Si status units can be connected to one control panel?
Up to 7 Sigma Si status units can be connected to a single Sigma XT control panel using the two-wire RS485 data connection, with a maximum total cable length of 1200 metres from the control panel to the last status unit.
What is the difference between the various Sigma Si models?
The range includes 6-lamp and 10-lamp versions. Basic units (K9110000M8) provide status indication only, whilst advanced models add mode select keyswitches (K911100M8), manual release capability (K911010M8), or both functions combined (K911110M8/W911113M8).
Are weatherproof versions available?
Yes, IP65 weatherproof versions are available across the range with model codes beginning with ‘W’. These units feature larger enclosures (256 x 170 x 60mm) and are suitable for harsh environmental conditions whilst maintaining full functionality.
What status information do the units display?
The units display comprehensive system status including fire zone conditions (zones 1-3), fault indications, released status, imminent discharge, disabled conditions, hold activated status, and auto/manual mode indication. 10-lamp units provide additional zonal fire indication.
How does the countdown timer function work?
The integrated countdown timer displays the time remaining until extinguishant release, providing clear visual indication during the pre-discharge warning period. This allows personnel to monitor the countdown and take appropriate evacuation or abort actions if necessary.
Can the manual release function be used independently?
Units equipped with manual release capability (K911010M8, K911110M8, W911113M8) feature protected dual action manual release switches that can initiate extinguishant discharge independently of the main control panel, providing essential backup release capability.
