2.1 EXHAUST HOODS

A. The hood shall be constructed of 18 & 20 gauge (type 304) polished stainless steel. Hood shall have fire suppression system factory installed into the hood system. Activation of the mechanical fire suppression system shall be by 212 or 280-degree fusible link (30” vs. 36” sizes). Fire suppression agent will be Amerex 660 Low PH wet chemical suppressant. Unit shall include centrifugal fan with air delivery of 380 to 610 cfm depending of calibration of unit. Unit shallinclude fuel shutdown option for Gas, Electric or Dual Element Devices. The hood system will also have multiple alarm and monitoring contacts factory installed into the hood.

233814 Page 3


C. Hood system include commercial-grade grease extractor type, high efficiency cartridge style baffle filters of adequate number and sizes to ensure optimum performance in accordance with manufacturer’s published information. The filter housing shall terminate in a pitched, full-length grease trough, which shall drain into a removable grease container.

D. Shatter proof light fixtures shall be included in the hood system. Wiring shall conform to the requirements of the National Electrical Code (NEC #70).

1. Pre-Installed Fire protection system to provide duct entry, plenum, and surface protection for hood system and equipment located below ventilator.

2. System interconnected with included shunt trip breaker and/or gas solenoid valve of equipment located below ventilator for power and fuel shutoff during system actuation.

E. Environmental Monitoring / Internal Monitoring / Pre-Suppression

1. Two temperature sensors are located on the inner face of the hood; one at a medium set point, the other at high. Under cooking conditions, when the medium set point is reached, the fan is turned on high. This feature dissipates the heat from the area but also draws it into the unit, past the fusible links in the system. If temperatures continue to rise and the high temperature set point is reached, the system reacts by shutting down power to the range prior to suppression system release. When this occurs, the unit’s internal alarm is activated so that occupants are notified that the system is working to prevent further escalation of a potential fire. This is considered two stages of pre-suppression, where the unit is interacting with the cooking environment - working to minimize the risk of a fire event

Should temperatures continue to rise, fire is present. The fusible links will melt, mechanically actuating the suppression system and releasing a low PH wet chemical agent across the cook-top. At actuation, the system will also make a second attempt to shut down power to the range; in the event of a flash-fire, or something that happens too quickly to register with the temperature sensors. The system will continue to sound its internal alarm while also communicating a “fire code” back to a monitored alarm panel.

The PLC Self-Monitoring-System also monitors the entire suppression assembly for completeness and continuity. If the suppression system is ever compromised through a loss of pressure or broken connection, or tampering of any kind, the unit reacts by shutting down power to the range. In this case the suppression system is compromised therefor the range shouldn't be in use. Under this condition, the system communicates a separate "maintenance code" saying that the unit is down and needs service. When preemptive shutdown occurs, the system and the cooking equipment will not come back on-line until the GRRS is reset.

F. Accessories

1. Manual Pull Station (MPK) – Mechanical assembly allowing the fire suppression system to be actuated manually normally located at the point of egress.

2. The CLOCKBOX (CLBX) – Cooking Element Time-Out System allowing for separate control functionality over when the appliance is used.

3. NSF (NSF) – The hood system can be upgraded to the NSF Standard 4. Handicapped Accessible Controls (ADA) – Separate control system designed to mirror the

front-end controls of the hood, to be installed at under counter-top height. 5. Powder Coating (PC) – The hood system can be powder coated in a variety of standard

colors, the manufacturer can also color match. 6. NFPA101 Upgrade (NFPA101) – Combines MPK, CLBX and an upgraded fan to deliver

>500cfm in order to comply with the requirements of the NFPA Life Safety Code.

Show on drawings overhead or rear support for equipment specified in this section. Specify requirements for support in Section 230529.

B. Interconnect ventilators to service utilities.

3.2 FIELD TESTING

A. Functional Test: using manufacturer-supplied procedure, short internal sensors to demonstrate shutdown and communication features.

B. Puff Test: using manufacturer supplied test cylinder, replace suppressant cylinder in system with test (nitrogen only) cylinder. Replace fusible links in line with a “test link”. Cut the test link and allow the system to actuate, performing all of its standard functions.

3.3 CLEAN-UP

A. At completion of the installation, clean and adjust equipment as required to produce ready-for-use condition.

B. Where stainless-steel surfaces are damaged during installation procedures, repair finishes in order to match adjoining undamaged surfaces.
