Smoke Guard 200 User manual

Codes and Standards. The M200/M400 systems work in
conjunction with fire-rated elevator doors to exceed the NFPA
and IBC requirements for a smoke and draft control assembly.
This enables the elevator to open directly onto the corridor.

System Description. The Smoke Guard system
Models 200/400 (M200/M400) create a code
compliant smoke- and draft-control assembly
when paired with common fire-rated elevator
doors. The Smoke Guard DuraNet™ screen
assembly consists of a reinforced transparent
material connected to flexible magnetic strips.
These magnets adhere to either required
full-length ferrous metal rails (M200) or the
existing ferrous elevator door frame (M400) as
the system deploys creating a tight seal. M200/
M400 units use standard 120 VAC building
power and may be connected to standby power.

Fail Safe Secure. M200/M400 systems operate on a fail safe
basis, on loss of AC power the screen will deploy. There is a
deployment delay on power failure built into the system to
avoid nuisance deploys on brief power outage.
Battery Backup. M400 units may be specified with an internal
battery backup. This feature is not available in M200 units.
Listed Releasing Device. The M200/M400 features a
releasing device tested in accordance with the UL 864
standard by Intertek Laboratories.
Rewind Switch. The Smoke Guard system screen rewind
switch may be activated from both sides of the screen.
This feature allows elevator occupants to exit from the
elevator car using the interior (shaft side) of the switch. The
screen will then redeploy after egress, as long as the smoke
detector continues to be activated, providing continued
smoke protection for the elevator hoistway. In the event of
power outage, the vertical edge of the curtain can be pushed
away from the rail to allow passage with a force less than
15 lbs. as referenced by the ICC.

System Operation. Smoke Guard elevator systems
are designed to protect elevator openings and
shaft from vertical smoke migration. The system
will deploy when the smoke detector in the
elevator lobby goes into alarm (or on loss of power
to the unit). The system is not designed to deploy
on general alarm. As the lobby smoke detector
goes into alarm, the elevator will automatically
return to the recall floor. If an elevator occupant
were to encounter a deployed M200/M400, a
screen rewind switch located on both sides of the
screen will allow for egress. If smoke is still actively
being detected, the screen will then redeploy to
seal the opening. As power is restored, the screen
will automatically rewind into the housing.
Installation. All Smoke Guard units are installed
by factory trained and certified personnel. There
is minimal preparation work. Installation requires
a clear, plumb, unobstructed wall surface above
the hoistway door, 120v AC power and a smoke
detector.
