You have not pressed BOTH the RESET button and the DISABLE buttons simultaneously, you
have ONLY pressed the DISABLE button. To put the VLF into STANDBY you press and hold
down the DISABLE button until the AutoLearn LEDS and DISABLED LED blink. This means
keeping the button pressed for about 6 seconds. You do the same again to take the detector out
of STANDBY. So, what you are doing is the 1st stage of putting the detector into/out of
STANDBY. To make IFF work reliably, you need to press the RESET button BEFORE the
DISABLE BUTTON. Several seconds can elapse between pressing these buttons but take care
that you do not RESET the detector by accident.
Can the deflector be removed from the VESDA LaserFOCUS exhaust?
It is a tight fit but it can be removed. With all VESDA detectors, we recommend returning all
sampled air from the exhaust into the sampled environment.
How do I change the filter on my VESDA LaserFOCUS?
Refer to the VESDA Maintenance Guide, available on the website under www.xtralis.com for full
details. VLF detectors need to have the front cover lifted. Secure the replacement filter and
acknowledge the action via a configuration tool (VSC, VSM or programmer).
What do you recommend that the four VESDA LaserFOCUS alarm relays be used for?
‘Alert’, ‘Action’, ‘Fire 1’ and ‘Fire 2’. Check whether your local codes require specific relays to be
fixed. VLF has action and fire set to specific relays.
