From
the 1st November 2019 a new, DLA Fire Shutter Drive will
be available from GfA UK. This product was launched at
our Open Day on 22nd October where it received a great
deal of interest.
GfA has been supplying tried
and tested fire door drives for over 20 years. Due to a
change in the standard, from 1st November 2019, we have
undertaken some fundamental changes to upgrade our
drive, which we believe now meets the criteria of the
new standard.
The main change initiated by
EN16034 is Ability to Release and Durability of the
Ability to Release which our new design addresses head
on.
A solenoid system is energised to release
using a 24Vdc alarm signal. Our new Actuator release
mechanism is energised to hold, therefore if the power
is lost, the actuator will release.
Features of
the GfA DLA fire shutter drive include:
- close
in the event of power being lost
- an
energised-to-hold actuator releases the mechanism and
triggers a controlled gravity descent.
- the
actuator has a permanent 24Vdc supply which when
interrupted by the fire alarm, initiates the
controlled descent.
All
assembled drives are factory tested to ensure fire alarm
controlled descent, as required by the standard.
The DLA fire shutter is available on GfA 150, 250, 600,
800 and 1,000 drives.
