2. The fabric curtain shall be manufactured from X32K woven glass fiber cloth incorporating a ' Panama' weave for increased stability. The woven glass fiber fabric shall have a nominal weight of no less than 540g/square meter and shall be UL listed for at least one hour. A fabric grab strap shall be mounted on the inside of the cab for manual egress.

** NOTE TO SPECIFIER ** Fabric egress slot is optional. Delete if not required.

3. The fabric curtain shall include a fabric egress slot to be outlined by stenciling. The curtain fabric will include an overlap with magnets at the center. A fabric grab strap will be mounted on the pull side of the egress slot at 42 inches A.F.F.

C. Three-Hour Fire-Rated Automatic Smoke Curtains: Model DSI SD-240GS by Door Systems, Inc.

2. The fabric curtain shall be manufactured from C41000WK woven glass cloth incorporating a ' Leinwand' weave for increased stability. The woven glass fiber fabric shall have a nominal weight of no less than 540g/square meter and shall be UL listed for three hours.

** NOTE TO SPECIFIER ** Fabric egress slot is optional. Delete if not required.

2.3 PERFORMANCE REQUIREMENTS

A. Air Leakage: Not to exceed 3 cfm (0.001416cu.m/s) per sf of door opening.

** NOTE TO SPECIFIER ** Select first paragraph below for DSI SD-60GS and DSI SD-240GS. Select second paragraph below for Model DSI 600. Delete paragraph not required.

B. Fire Rating - UL-10D: The enclosure shall be rated at the same rating as the curtain fabric.

C. Fire Rating - UL-10D: One hour fire rated and labeled.

2.4 COMPONENTS

A. The curtain head box shall be manufactured from 18 gage (1.2mm) galvanized steel. The enclosure shall be rated at the same temperature as the curtain fabric.

B. Removable cover plates shall be incorporated to allow access to the curtain rollers.

C. A weighted bottom bar shall be provided to prevent deflection and ensure correct operation under gravity.

D. The roller shall be constructed from an octagonal tube which will incorporate a 24v D.C. motor and gearbox and a sealed heavy duty ball bearing assembly.

E. A motor control circuit housed in a steel enclosure shall be mounted onto the motor end of the head box.

F. Provide each motorized curtain with back Electromagnetic force controlled speed of descent of no less than 6 inches per second and no more than 24 inches per second.

2.5 OPERATION

A. The smoke and fire curtain shall deploy upon a signal from the fire alarm system in an emergency situation.

B. The system must be proven to "fail safe" to the operational position on total loss of primary and auxiliary power. The system must contain a housed battery system at the Group Control Panels.

C. Under normal operating conditions the curtains shall be held in the retracted position via the motors operating at low voltage. The manufacture must be able to confirm that the motor windings are suitable for this type of operation.

D. Upon activation of the fire alarm the control panel shall remove the supply voltage and the curtain shall descend under the power of gravity in a controlled manner. A dynamic braking system housed in the motor control circuit shall control the speed of the descent of the curtain. The descent shall be electronically synchronized on overlapping curtains with a bottom bar.

E. To retract the curtain, the control panel shall supply 24v to the motor control circuits and motors will drive the curtains to the upper position. As the bottom bar or stopping bar hits the curtain head box a current limiting circuit will step back the voltage and current and hold the bottom bar in the retracted position.

F. Limit switches shall not be used to control the upper position of the curtain.

** NOTE TO SPECIFIER ** Braking system is optional. Delete if not required.

G. Braking System: Allows a two stage descent during gravity deployment. Should the main power fail to the group control panel, the supply shall be automatically switched to the integral standby battery.

1. The curtain shall remain in the retracted position for 1 hour (fully retracted loaded system).

2. The curtain shall remain fully operational until the battery low voltage cut off facility reads a voltage of 21v; the curtains shall then safely descend under the power of gravity to the operational position.

H. Group Control Panel: Provide Group Control Panel (GCP) capable of controlling up to 5 no. BLE24v motor assemblies.

1. During normal operation, the GCP will provide a 24v AC supply to the curtain motor holding them in the retracted position.

2. Should smoke be detected, the fire alarm contact in the GCP will be opened by the fire alarm control system, the GCP will remove the 24v supply to the curtain motors and the curtains will 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. All "Push to Exit" buttons must contain internal battery back-up power supply for fail safe operation for ICC ES requirements.

L. Weight of bottom to be 1.5 pounds per linear foot of curtain for secondary means of egress for compliance with ICC ES requirements.
