Frequently Asked Questions for the Model 1500 Smoke Curtain
- How is the Smoke Guard system M1500 listed and labeled?
Smoke Guard system (SGS) products are listed and labeled by Intertek (Omega Point Laboratories and ETL) in accordance with UL 1784 and UL 864 standards. Our systems are also recognized by the International Code Council (ICC) Evaluation Service, the California State Fire Marshal, and numerous state and local building jurisdictions. The Smoke Guard system exceeds the smoke containment standards prescribed in the International Building Code (IBC). See our Agency Approvals page for more information on our product listing and labeling.
- How does the curtain work with the side guides?
The M1500 consists of a smoke rated curtain coated with a para-aramid material contained in a housing above the ceiling. The curtain is secured vertically on both sides by curtain loops secured by guide rods. Guide rods thread through guide rails anchored to the side walls. The curtain assembly is equipped with a bottom bar to seal the curtain at the bottom and provide edge sensing to detect obstructions to the deploying screen.
- Can the side guides be imbedded in the wall?
Yes. The Model 1500 side guides can be both surface mounted or embedded in the wall. Please specify which option you prefer when ordering the product.
- How do you egress through the Model 1500 curtain?
The deployed Model 1500 curtain can be raised by using the push paddle wall switches located on each side of the screen. If primary power is lost, each unit is powered by a UPS-battery back- up system that will continue to operate the curtain. If both primary and battery back-up power are lost, the clutch drive system is disengaged to allow the curtain to be raised manually. Loops attached to the deployed curtain allow anyone to raise it manually to allow egress.
- Can the M1500 be used at locations other than the elevator where smoke containment is required?
Yes. In addition to the elevator lobby, the Model 1500 is well-suited to atriums, countertop enclosures, and gas suppression system support.
- Does the Model 1500 have alternate sources of power?
Yes. Each Model 1500 unit uses an integrated UPS and battery back up.
- How does the unit deploy in the event of a fire?
The system is deployed upon a signal from the local smoke detection system located in the elevator lobby, corridor or atrium being protected. As many as four Model 1500 units can be connected in parallel to one smoke detector and end of the line terminator. System deployment and retraction are powered by 120-volt AC power. The unit is also equipped with a 24-volt DC battery back-up system that is recharged from the electronic controls. When required the system can also be connected to building standby power. The controls include a universal power supply that can be adapted to foreign electrical current requirements.
- What does "return" mean when I am specifying the Smoke Guard system?
We refer to the depth or distance between the wall and the face of the elevator door frame as a "return". Model 1500 has specific returns associated this system, consult your local SGS distributor or SG Customer Service on return sizes for your project.
