Autocall Audible Only Notification Appliances, Weatherproof Ceiling Mount Electronic Horns, Model Series A49AO

UL ULC Listed FM Approved ES Addressable Notification Appliances Only Notification Appliances Weatherproof Ceiling Mount Electronic Horns Model A49AO addressed and controlled low power ES Audible Only A O Notification Appliances Advanced addressable notification controlled by IDNAC signaling line IDNAC SLCs provide regulated 29 VDC to allow horns to operate with SLC current Wiring supervision to each appliance to allow T tap connections for B circuits to simplify wiring Class A circuits require in out wiring Self Test Mode uses an on board sensor to detect the horn output and the status to the control panel Horns are controlled separately from visible appliances on the same with control panel selection of operation as Temporal Code 3 Time selectable as 20 beats per minute bpm 60 bpm or 120 Continuous or Temporal Code 4 Select a high or low output 6 dBA difference at the appliance or the controller with FACP mode selected at the appliance Unobtrusive Magnet Test diagnostics are available to assist checkout testing of the appliances and wiring Remove the cover to access the electrical test point Compatibility with ADA requirements see Installation reference Listed to UL Standard 464 and ULC Standard S525 indicator and Magnet Test feature Appliance LED can be selected to display each polling cycle to indicate supervision When the controller is in diagnostic mode the Magnet Test pulses the to indicate appliance address and can also be set to briefly sound horn to confirm operation design features include Rugged high impact flame retardant thermoplastic housing available a variety of colors and lettering Separate covers are available for replacement or to change the type onsite Covers can be easily removed without disturbing the connected avoiding trouble conditions Optional wire guards see Table 4 ES addressable horns ES addressable horns are individually addressed audible appliances that receive power supervision and control from an Autocall fire alarm control panel providing IDNAC Line Circuits SLCs see Table 5 1 ES Addressable Horn ES operation advantage ES addressable appliances on IDNAC SLCs provide audible and visible notification using a single two wire circuit also confirms connection to the individual notification appliance circuit This operation increases circuit supervision integrity providing supervision that extends beyond the appliance wiring current allows efficient IDNAC SLC operation IDNAC SLCs a constant 29 VDC source voltage is maintained even battery standby to allow horns on the same SLC to operate at voltage with lower current and ensuring a consistent current and voltage drop margin under both primary power and secondary standby Efficiencies may include the following Wiring distances up to three times farther than with conventional Support for more appliances for each IDNAC SLC Use of smaller gauge wiring provides installation and maintenance savings with high assurance appliances that operate during normal system testing will operate worst case alarm conditions installation and testing time separate controls on the same two wire SLC installation time and for both retrofit and new construction can be significantly When Class B wiring is used wiring can be T tapped to more savings in distance wire conduit size and utilization and installation efficiency Use of Self Test and Magnet Test features

latest status Rev 2 03 2021 Only Notification Appliances Weatherproof Ceiling Mount Electronic Horns Model Series A49AO ES diagnostics Features IDNAC SLCs are in diagnostic mode Self Test and Magnet Test features provide individual appliance testing With the Self Test feature appliance can be confirmed without leaving the control panel Additionally each appliance LED can be selected to pulse when it receives a supervision during normal operation Details Self Test Mode from the control panel allows on board sensors depending on the device type to detect its own horn output and then their status to the control panel Operation is by selected VNAC appliance groups and is either automatic all briefly simultaneously activated individually activated by applying a magnet Refer to control panel data sheet for more Self Test information see a list in IDNAC SLC controller reference Appliance Magnet Test this test mode in response to application of a magnet the appliance LED pulses sequentially to conveniently indicate the appliance address Appliance Magnet Test this test mode after the address is indicated by pulsing the appliance LED the horn will briefly sound to indicate correct operation Instrument Two TSIT second generation of the Autocall TrueStart Test Instrument adds testing of IDNAC SLC wiring and TrueAlert ES appliances to its ability to test IDCs and IDNet communications before
