this equipment INSTALLING read the System Sensor Voice Evacuation Application Guide which detailed information on speaker notification devices wiring and spe applications Copies of this manual are available from System Sensor NFPA 72 and NEMA guidelines should be observed System Sensor also installing fire alarm speakers in compliance with NFPA 72 UL 1480 and NEC 760 Important The notification appliance used be tested and maintained following NFPA 72 requirements CAN ULC S524 guidelines should be observed System Sensor recommends installing fire alarm speakers in compliance with CAN ULC and CEC Important he notification appliance used must be tested and following CAN ULC S536 requirements DESCRIPTION Sensor series of notification appliances offer a wide range of audible visible devices for life safety notification Our indoor speaker strobes with 7 field selectable candela settings The candela setting can be veri when the unit is installed by looking into the small window on the front strobe portion is designed to be used in 12 VDC 24VDC or 24V FWR wave rectified systems The speaker is designed to be used at either 25 70.7 volts and it will operate at any one of four input power levels Our strobes are suitable for dry and damp environments These products electrically backwards compatible with previous generation of System speakers speaker strobes and strobes With its low total harmonic the System Sensor L Series offers high fidelity sound output Speakers Strobes are public mode notification appliances intended to occupants of a life safety event The speaker is listed to ANSI UL 1480 mode and the strobe is listed to ANSI UL 1638 public mode ALARM SYSTEM CONSIDERATIONS System Sensor recommends installing fire alarm speakers in compliance NFPA 72 ANSI UL 1480 and NEC 760 System Sensor recommends installing fire alarm speakers in compli with CAN ULC S524 and Canadian Electrical Code DESIGN system designer must make sure that the total current drawn by the de on the loop does not exceed the current capability of the panel supply that the last device on the circuit is operated within its rated voltage The draw information for making these calculations can be found in the within this manual For convenience and accuracy use the voltage drop on the System Sensor website www systemsensor com calculating the voltage for the last device it is necessary to consider voltage drop due to the resistance of the wire The thicker the wire the the voltage drop Note that if Class A wiring is installed the wire may be up to twice as long as it would be circuits that are not fault The total number of strobes on a single NAC must not exceed 69 for volt applications products meet the light output profiles specified in the appropriate UL See Figure 6 1 CANDELA AND SPEAKER SELECTOR LOCATIONS Candela Box A0589 00 SETTINGS methods shall be in accordance with regional codes United States The National Electrical Code NFPA 70 and the National Alarm and Signaling Code NFPA 72 Canada CSA C22.1 Canadian Electrical Code Part I Safety Standard for Installations Section 32 must not be of such length or wire size which would cause the noti appliance to operate outside of its published specifications Improper can prevent the system from alerting occupants in the event of emergency To uncover the product wires and access hole remove the junction box a Philips head screwdriver See Figure 1 Route the field wiring through the conduit connector Optional for rigid conduit applications or applications which require a junction box Attach customer supplied extension ring for alternate See Figure 2B Prepare the wire connections by stripping about 3 8 of insulation from end of the field wiring Terminate the wires using UL ULC approved nuts Connect wires for speakers and or strobes See Figure 3 a Speaker speaker INPUT from the Amplifier Positive and Negative Connect speaker OUTPUT to the next appliance or EOL resister Strobe Connect the strobe INPUT from the FACP or NAC Positive and Connect the strobe OUTPUT to the next appliance or EOL resister NOTE SUPERVISED STROBE INPUT POWER System Sensor notifica appliances supervise the strobe power on the positive terminal In and output terminals are completely independent and must not be together Configure input power and or candela settings a Speaker See Figure 4 the VOLTS dial to select input
