D.	Roller: Constructed from octagonal tube. Incorporates a 24 VDC motor, gearbox, and a sealed heavy duty ball bearing assembly.
E.	Motor Control Circuit: Housed in steel enclosure mounted on motor end of head box.
F.	Motorized Curtain Electromagnetic Force Controlled Speed of Descent:
1.	Minimum: 6 inches (152 mm) per second.
2.	Maximum: 24 inches (610 mm) per second.
G.	Housed Battery System: Must be incorporated in the Group Control Panels for operation during total power loss conditions.
H.	Label each smoke containment system with the following information:
1.	Manufacturer's name.
2.	Maximum leakage rating at specified pressure and temperature conditions.
3.	Label of quality control agency.
2.5	OPERATION
A.	Smoke and Fire Curtain Deployment: Upon signal from fire alarm system in emergency situation.
B.	Total Loss of Primary and Auxiliary Power: System must be proven to "fail safe" to the operational position.
C.	Normal Operating Conditions: Curtains held in retracted position via motors operating at low voltage. Manufacture must confirm motor windings are suitable for this type of operation.
D.	Upon Activation of Fire Alarm: Control panel removes supply voltage and the curtain descends under power of gravity in a controlled manner.
1.	Descent Speed Control: Dynamic braking system housed in motor control circuit. Descent is electronically synchronized on overlapping curtains with a bottom bar.
E.	Curtain Retraction: Control panel supplies 24 V to motor control circuits. Motors drive curtains to the upper position. When the bottom or stopping bar contacts the curtain head box, a current limiting circuit steps back the voltage and current, holding curtain in the retracted position.
F.	Limit switches must not be used to control the upper position of the curtain.
G.	Braking System: Two stage descent during gravity deployment. If main power to group control panel fails, power is automatically switched to the integral standby battery.
1.	Curtain remains in retracted position for 1 hour (fully retracted loaded system).
2.	Curtain remains fully operational until battery low voltage cut off facility reads a voltage of 21 V. Curtains then safely descend under gravity power to operational position.
H.	Group Control Panel: Provide Group Control Panel (GCP) capable of controlling up to 5 no. 24v motor assemblies.
1.	During Normal Operation: GCP provides 24 VAC supply to the curtain motor holding curtains in the retracted position.
2.	Upon Smoke Detection: The GCP fire alarm contact is opened by the fire alarm control system. The GCP removes the 24 V supply to curtain motors and curtains descend under the power of gravity in a controlled manner.
I.	Open on Fire: Configured to be gravity fail safe.
J.	Test Facility: Key switch required.
K.	Push to Exit Buttons: Must contain internal battery back-up power supply for fail safe operation for ICC ES requirements.
L.	Weight of Bottom: 1.5 pounds per foot (2.23 kg per meter) of curtain for secondary means of egress for compliance with ICC ES requirements.
