FAQ
How many detection zones does the Sigma XT support?
The Sigma XT features 3 detection zones as standard, each capable of supporting up to 32 devices depending on the detector type. Any single zone or any combination of zones can be configured to trigger extinguishant release.
What extinguishant delay options are available?
The system offers configurable extinguishant delays from 0 to 60 seconds in 5-second steps, with a zero time delay option specifically available for manual release activation. The extinguishant duration can be set from 60 to 300 seconds, also in 5-second increments.
Can the system integrate with aspirating smoke detection equipment?
Yes, the Sigma XT includes a non-latching zone input option specifically designed to receive signals from other systems such as aspirating equipment, providing seamless integration with advanced detection technologies.
How many remote status indicators can be connected?
The system supports up to seven four-wire status indicators connected via a two-wire RS485 communication link, allowing comprehensive remote monitoring and control capabilities throughout the protected facility.
Is the system compatible with intrinsically safe environments?
Yes, the Sigma XT is compatible with intrinsically safe barriers and can be configured for use in hazardous environments where spark prevention is critical. This feature can be enabled through the programmable functions menu.
What power supply and battery backup is provided?
The panel operates on 230V AC mains supply with a 3 Amp power supply rating. Battery backup is provided by two 12V 7Ah sealed lead acid batteries connected in series, with temperature compensated charging at 27.6V DC nominal.
