DISCUSSION
The product covered in this Research Report is a Carbon Monoxide (CO) Detection System for use in nonhazardous locations such as commercial buildings. The detection system monitors the carbon monoxide
level in the surrounding air and activates the ventilation system when the gas level exceeds 50 ppm. If the
gas concentration rises above OSHA-recommended upper limits, an audible and visual alarm will be
activated. The performance and sensitivity of this Carbon Monoxide (CO) Detection System was evaluated
and accepted by an approved recognized testing agency.
An on-board microcomputer supervises and verifies the operation of the system and displays the status to
the indicator lights. If a malfunction occurs, the ventilation system is activated and a fault warning signal
is activated.
When this system is installed in accordance with the provisions of this General Approval, it should meet
the minimum safety standards of the Los Angeles City Electrical Code.
For this General Approval to be valid on any installation in the City of Los Angeles, an engineer or
inspector of the Department of Building and Safety may make a determination that all conditions of the
General Approval required to provide equivalency have been met.
This General Approval is in accordance with Section 93.0303 of the Electrical Code pertaining to "New
Materials and Methods of Construction", and does not waive the requirements of the City of Los Angeles
Building Code.
This General Approval is neither a product endorsement nor a certification of function of accuracy of the
approved item.
