Q During installation, how can I overcome the problem of a floor void that is too shallow to adequately fit a nozzle?
A: Our recommendation is that for floor voids, where a nozzle cannot be fit in the void space is as follows: The floor should be fitted with evenly placed grill tiles over a minimum of 25% of the floor area. Include the floor void in the total volume and design at a high hazard concentration.
This recommendation will not be found in the standards or any published document, and reflects our practical solution especially if the cable bundles are relatively small.
