How Strong Do I Need to Build My Wall To Support A Clean Agent Sphere

When mounting cylinders to concrete masonry, brick walls, columns or poured concrete walls always:

• Use hot dipped galvanized P1000 Unistrut channel.
• Use the mounting bracket  as a template, drill two holes through each P1000 Unistrut channel to match the top and bottom holes on the bracket back at a distance of 11 – 1/8”.
• To prevent spalling, do not use a rotary hammer drill for masonry drilling.

Design Guidelines Spot Smoke Detectors:

For smooth ceiling applications, the distance between detectors shall not exceed their listed spacing. Detectors should be placed with one half the listed spacing from all walls or partitions. These rules of thumb are adjusted for other ceiling types and construction. Refer to NFPA 72 for specific instructions.

NFPA Guidelines

Design Guidelines For Air Sampling Smoke Detection:

Air sampling smoke detection pipe layout should follow manufacturer recommendations, which generally includes balanced pipe lengths, elbows and fittings. Sample ports should be spaced according to spot type detection guidelines.

Room Integrity

Spaces dedicated for mission critical operation that require specialized fire protection systems must be sealed well enough to maintain design concentration for 10 minutes. This means all penetrations into the space must be sealed, doors must be fitted with sweeps and seals. Ceiling tiles must be installed and clipped in place within 8’ of all discharge nozzles

Room Venting

Rooms protected by specialized fire protection systems may require additional venting to relieve pressures experienced during discharge. While this is always a consideration with inerting agents, it sometimes applies to chemical agents as well. To determine venting requirements, calculation tables are required. Fill out Ask the Expert page and request assistance with venting calculations.
