They are commonly used in construction machinery, garbage trucks, delivery vans, and other vehicles and equipment that can pose a danger to pedestrians or workers. When a vehicle is reversing, the reversing alarm usually emits a loud beep, which is a warning sign that alerts people who may be walking or working nearby.Warning alarm is similar, but may be activated in different situations, such as when a vehicle is turning or changing lanes. The purpose of these warning alarm is to help prevent accidents and injuries, especially in busy and crowded environments where visibility may be limited. Although some areas may have noise restrictions related to reversing and warning alarms, many countries require certain types of vehicles and equipment to have these safety features installed and functioning properly. This helps keep drivers and pedestrians safe and can help prevent accidents and injuries in the workplace and on the road.Suitable for: trucks,plant,diggerCE EMARK nylon 12-48V manual adjustable 97dB 107dB output car reverse hornGeneral specifications:Output level97 or 107dB ± 4dB at 1.2MVoltage12-48 VDCCurrent drainless than 0.6Atemperature range-40 to 85 ºCFrequency1400HzDuty cycle0.85 pulse per second 50% ON 50% OFFweight355g ± 10%Dimensions129*69*74mmApplications:For cars, trucks, construction machinery, with 12V to  48VDC system, made for heavy duty applications in medium or high noise area.With 3 wires, have 2 different outputs which is 97 and 107dB, you can wire to have the output you need. Main features:Manual adjustableReinforced nylon housing IP68 waterproof speaker, epoxy ensamsulated PCBPolarity protectedEasy to install with universal mountingLong warranty 2 year warrantySAE TYPE B & SAE TYPE CRoHS and CEAlarms of different housingswire connection version ot studs version available for some housingsConnctors optional for wire connection versionsbeep sound, white noise sound, vocal messages available for some modelsIntelligent alarms with beep sound, white noise sound available.Intelligent alarms with night mode, silent mode avaible.Quick details for all series alarmsSeriesSizeSoundRemarkB00127*70*73.5mmbeep soundintelligent models availableB10dia 60*46.3mmbeep sound B20103.5*40.5*71mmbeep, white noise, bespoken messageintelligent models availableB30103*44.5*68mmbeep, white noise, bespoken messageintelligent models availableB40129*69*74mmbeep sound, bespoken messagemanual adjustable availableB50102*44.5*69.5mmbeep, white noise, bespoken messageintelligent models availableB60127*95*77mmbeep, white noise, bespoken messageintelligent models availableB70127.5*79*82mmbeep, white noise, bespoken messagemodels with night mode availableB80 S105*71.8*70mmbeep, white noise, bespoken messagemodels with night mode availableB80 L130*76*88mmbeep, white noise, bespoken messagemodels with night mode availableBJ58*30*59.5mmbeep, white noise, bespoken message B90 beep, white noise, bespoken messagemodels with night mode availableMore information about the alarm:Alarm drawing, sizes in mm  FAQQ1: what is the MOQ?YUEDA: No MOQ required.Q2: what it the lead time?YUEDA: 2-4 weeks, for regular models, we usually prepare some in stock, so shipment could be made very soon.Q3: Can I have some free samples for evaluation first?YUEDA: Sure.
