Concerns Safety Safety Occupational Health and Safety Administration (OSHA)Occupational Health and Safety Administration (OSHA) Illumination StandardsIllumination Standards Placement of these SystemsPlacement of these Systems National Fire Protection Agency (NFPA) REQUIRES a MINIMUM Lighting Duration of 1.5 HOURS when Normal Lighting is Not Available.National Fire Protection Agency (NFPA) REQUIRES a MINIMUM Lighting Duration of 1.5 HOURS when Normal Lighting is Not Available.

Solution Build an Efficient System with Long Lasting Batteries and Lights Build an Efficient System with Long Lasting Batteries and Lights Exceed the Safety Standards Set by OSHA and the NPA Exceed the Safety Standards Set by OSHA and the NPA Incorporate Wireless Data Transmission into Emergency Lighting System Incorporate Wireless Data Transmission into Emergency Lighting System

Hardware Components Cont. Charging Circuitry Charging Circuitry –Detect State of Charge –Fast Charge –Float Charge 900 MHz XCite Wireless Module 900 MHz XCite Wireless Module

Hardware Components Long Lasting Phantom PAR-36 Light Emitting Diodes Long Lasting Phantom PAR-36 Light Emitting Diodes Two 6-Volt Carefree Eagle Picher AGM Batteries Two 6-Volt Carefree Eagle Picher AGM Batteries

Battery Discharge Curve The AGM Batteries Should Provide Light for at least 15 hours

Remote Monitoring Options X10 Technology vs. RF Serial Transmission Number of Nodes Number of Nodes –256 vs Noise Noise –Electrical devices interfere when using X10 –Wireless devices interfere with RF reception Data Collision Data Collision –X10 transmits slower Range Range –X10 is indefinite with repeaters –RF is based on module and antenna Cost Cost –X10 incurs numerous hidden add-on costs –RF is less expensive overall

900 MHz vs. 2.4 GHz Data Rate Capacity Data Rate Capacity Operating Distances Operating Distances –Wave Propagation –Penetrating Obstacles Signal Bending Signal Bending

Wireless Data Transmission XCite OEM RF Module XCite OEM RF Module Operates on the 900 MHz frequency band Operates on the 900 MHz frequency band Can support up to nodes Can support up to nodes Indoor Range of up to 300 ft. Indoor Range of up to 300 ft.

Test Plan Create Charge/Discharge Curve Create Charge/Discharge Curve –Monitor Voltage/Current vs. Time –Compare Curves to Data Sheets Wireless Transmission Range Test Wireless Transmission Range Test –Test in Urban Setting
