BOX OPTIONS Indoor Products x 4 x 1 Double Gang Octagon SBBCRL WL ceiling This manual shall be left with the owner user of this equipment INSTALLING read the System Sensor Audible Visible Application Reference Guide provides detailed information on notification devices wiring and applications Copies of this manual are available from System Sensor 72 and NEMA guidelines should be observed The notification appliance used must be tested and maintained NFPA 72 requirements DESCRIPTION Sensor series of notification appliances offer a wide range of audible visible devices for life safety notification Our 4 wire horn strobes come 10 field selectable tone and volume combinations and 7 field selectable settings Intended for indoor applications and approved for ceiling installations horn strobes and strobes are public mode notificati2on appliances in to alert occupants of a life safety event The horn is listed to ANSI 464 requirements public mode and the strobe is listed to ANSI UL 1638 mode Sensor strobes are designed to be used in 12 VDC 24VDC or 24V FWR wave rectified systems System Sensor AV devices can be activated by a fire alarm control panel or power supply Refer to the appropriate alarm control panel manufacturer or power supply for more information Sensor ceiling 4 wire horn strobes are electrically backward compat with the previous generation since 1996 of notification appliances They enabled with System Sensor synchronization protocol which requires to a power supply capable of generating the System Sensor syn pulses a FACP NAC output configured to System Sensor synchro protocol or the use of MDL3 module to generate the synchronization ALARM SYSTEM CONSIDERATIONS National Fire Alarm and Signaling Code NFPA 72 requires that all noti appliances used for building evacuation installed after July 1 1996 temporal coded signals Signals other than those used for evacuation do not have to produce the temporal coded signal System Sensor spacing notification appliances in compliance with NFPA 72 DESIGN system designer must make sure that the total current draw by the devices the loop does not exceed the current capability of the panel supply and 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 the manual For convenience and accuracy use the voltage drop on the System Sensor website www systemsensor com calculating the voltage available to the last device it is necessary to the voltage due to the resistance of the wire The thicker the wire the the voltage drop Wire resistance tables can be obtained from electri handbooks Note that if Class A wiring is installed the wire length may up to twice as long as it would be for circuits that are not fault tolerant total number of strobes on a single NAC must not exceed 69 for 24 volt TONES Sensor offers a wide variety of tones for your life safety needs includ temporal 3 pattern second on second off second on second second on 1 off and repeat which is specified by ANSI and NFPA 72 standard emergency evacuation signaling select the tone turn the rotary switch on the back of the product to the setting See Figure 1 horn settings can be found in Table 1 The standard mini horn sound is 3.1 kHz The legacy sound of the Advance line is EM Electro mechanical this hops frequencies 2Hz and 4Hz For EM Coded positions temporal coding must be by the NAC If the NAC voltage is held constant the horn output will constantly on 1 AUDIO SELECTOR 3 LIGHT OUTPUT VERTICAL

provides two independent circuits one for the Horn and for the Strobe The current draw for each Strobe setting is listed in 3 and audibility ratings for each Horn Tone setting is listed in Table 4 3

constant the horn output remains constantly on kHz Non Temporal kHz Non Temporal kHz Temporal kHz Temporal kHz Coded AND MOUNTING wiring must be installed in compliance with the National Electric Code the local codes as well as the authority having jurisdiction Wiring must be of such length or wire size which would cause the notification appli to operate outside of its published specifications Improper connections prevent the system from alerting occupants in the event of an emergency sizes up to 12 AWG 2.5 mm may be used with the mounting plate The plate ships with the terminals set for 12 AWG wiring wire connections by stripping about 3 8 of insulation from the end of wire Then slide the bare end of the wire under the appropriate clamping and tighten the clamping plate screw We provide a wire strip guide See 6 for wiring terminals and strip guide reference finish should not be altered Do not paint not over tighten mount
