Reply To: Accordion style fire shutters

Good question. The size limits in the OBC are different for both. The required FRR is also affected by the answer. As the shutter is initiated by the fire alarm, I would expect it would by tested monthly and considered an ancillary device under CAN/ULC-S536. This would require electrical supervision of the power source? The back up battery would also require testing and maintenace. All this would be identified in the fire safety plan. I am curious to know if these panels hold up over time? What about all those moving parts? What preventative maintenace can be put into place to ensure that the correct operation of the device does not soley fall onto the fire department inspector when he shows up to conduct an inspection.(perhaps an annual inspection by the manufacturer). What happens when the business/property changes ownership? Objective-Based Codes???…
