Summary
The Kentec K91000M10 Extinguishant Hold Off Switch Unit is a critical safety device designed to provide additional control over automatic fire suppression systems. Compatible with all of Kentec’s EN approved extinguishing control panels, this robust unit offers the vital option to temporarily hold the extinguishant release countdown when activated, providing essential flexibility during emergency situations.
This sophisticated control device allows additional time to evacuate the protected area prior to extinguishant release or enables operators to take preventive actions to avoid unwanted discharge. When the Hold Off push button is activated during an extinguishant release countdown, the timer immediately stops for as long as the button remains pressed, with activation clearly indicated on the main control panel.
Featuring a robust grey enclosure with a distinctive green shrouded push button, the K91000M10 incorporates thoughtful design elements to prevent inadvertent activation whilst ensuring reliable operation when needed. The unit can be surface mounted or flush mounted using the optional M10FCLGT collar, providing versatile installation options to suit various site requirements whilst maintaining professional appearance and functionality.

FAQ
How does the Hold Off function work during an extinguishing sequence?
When activated during an extinguishant release countdown, the Hold Off button immediately stops the countdown timer for as long as the button remains pressed. The activation is clearly indicated on the control panel, and releasing the button allows the countdown to resume from where it stopped.
What happens if the Hold Off button is pressed when there’s no active countdown?
If the Hold Off button is activated outside of an extinguishant release countdown sequence, it will trigger a fault condition on the control panel, providing immediate notification that the system has been inappropriately activated.

The K91000M10 is compatible with all EN approved Kentec extinguishing control panels, including the Sigma XT range, ensuring universal compatibility across Kentec’s fire suppression systems.

Yes, the K91000M10 can be both surface mounted or flush mounted using the optional M10FCLGT flush mount collar (Grey), providing flexible installation options to suit different aesthetic and practical requirements.
Why does the button have a shroud?
The shrouded design prevents inadvertent activation of the Hold Off function, ensuring the system can only be deliberately operated during genuine emergency situations whilst maintaining easy access when required.

The K91000M10 features a grey enclosure with a green shrouded push button, whilst the KB91000M10 has a white enclosure with a red shrouded push button that complies with BS7273-1 colour coding standards.
