Description:

Hose Stream 120® Horizontal SR (Sliding Retract) egress deploys along the X-axis from wall-to-wall for deployment and retraction. The galvanized steel box is recessed into the wall. Single roller 12-inch by 12-inch box for 40-feet in deployment length (Z-axis) and 10-feet in deployment height (X-axis) and for multi-roller 9-inch by 15-inch 80-feet in deployment length (Z-axis) and 30-feet in deployment height (Y-axis).

Box is recessed into the wall cavity or flush with the face of drywall for wall-to-wall deployment and retraction. The guides use a metal tab system to deploy and retract the system. There is a membrane switch on the Steel-Tex® to retract the curtain from 36-inches to 72-inches.

Length and Drop Height Limits- Length 40-feet, Height 20-feet
UL 864 listed Battery Back Up- Standard 2 12-volt batteries in UL 864 listed Control Panel and Motor Controller typically 40-feet away from Curtain head box for 14-2 low voltage wiring, 12-2 low voltage wiring for 80 feet away from Curtain headbox.
Control Panel-- connected directly to Addressable Fire Alarm system by closed contact that opens on fire signal from Smoke/IR detector. The contact type must be volt free, dry contact. Each Control Panel draws 7 amps. Control Panel requires 120 volts, typically a 20-amp circuit breaker. The circuit shall be a dedicated circuit marked life safety. Each control panel can control 4 motors. Each curtain roller utilizes 1 motor. If the curtain requires up to 8 motors, then a second Control Panel will be wired in series. If the curtain requires 12 motors, then a third Control Panel will be wired in series. Up to 9 Control Panels may be wired in series.
Smoke Detector Activation- the Smoke/IR detector wiring can be wired directly to the Control panel if there is no central fire alarm system in the building.
Egress- Sliding Wall Retract Button (SWR) membrane switch
Obstruction Sensor- Obstruction sensor option is a class 1 laser beam that is set next to bottom bar to annunciate after a period of 15-minutes to warn of an obstruction. This sensor can be connected to building management system (BMS relay) for monitoring.

FREQUENTLY ASKED QUESTIONS (FAQ):

Can I use the Dual Hose Stream 120® Horizontal SWR be utilized for opening in a fire wall or fire barrier?

Yes, Openings in fire walls and fire barriers must be UL 10B with the hose stream test per IBC Table 716.

Does the fabric come in various colors?

The fabric comes in gray only.

Do the side boxes come in different colors?

Yes, Ral colors, white, gray, black, standard and all other Ral Colors optional. USSF recommends factory-etched primed and paint in field so that the sheen will match better.

Can the top guides be fully recessed in ceiling and what is the minimum size?

Top guides are a manufactured steel extrusion 2-inches in width and 4-inches in depth. The guides can be recessed in the ceiling cavity typically 2-inches.

What is the speed of the curtain?

NFPA 80 Chapter 21 Fire Protective Curtains states that drop speed must be 6-inches to 24-inches per second.

Can I use my curtain to deploy and retract by a remote key switch, as I am using it to close off an area?

Yes, the curtain can be controlled by a remote key switch in view of the curtain to deploy and retract the curtain. There is an optional "door mode" software that will allow the user to deploy the curtain without any beeping of the control panel which would normally beep when curtain is deployed.

Does the curtain automatically reset when the smoke/IR detector or fire alarm system reset to normal non-alert mode?

Yes, the system is automatic, once the closed contact from FAS opens, the curtain drops to its operational position and when the FAS contact closes, the curtain motors engage, and the curtain retracts back inside its headbox.
