Large room testing with 2 Blowers
2000 Fire Door-Fan Manual
Models N64 and L64
Use the second blower panel. Install it above the lower blower
panel. Install the second blower in the upper panel. For added
security:
1. mount the panels on the far side of the doorstop so the
weight of the blowers pulls them into the stop
2. apply 2-inch clear tape to both sides of the upper panel
where it contacts the doorframe
Use second cord set from console to control the speed of blower #2.
Models E64 and J64
Use speed controls mounted on blowers to adjust speed.
Read flow pressure from blower #1 then move the flow pressure tube
from blower #1 and connect it to
blower #2 for second flow pressure reading.
