Broadcasting, calling, communication can through the handle, push the button in the handle when broadcasting, calling and communication, off the button, the other side off hook, then can talk Outdoor station Model:DT002 Waterproof, no built-in speaker, comes with external YH102A ( 8Ω 10W) loudspeaker. And the 8Ω5W built-in speaker is optional. Broadcasting, calling, communication can through the handle, push the botton in the handle when broadcasting, calling and communication, off the button, the other side off hook, then can talk. Driver s room station Model:DT Built-in 8Ω 5W speaker,meet the requirement of dialing and calling on the driver from other party. Driver can make the external broadcast, calling through the handle. Pressing the middle button of the handle when broadcasting. Finshing the broadcasting, loose the button. When other people offhooks, the calling is reached. 2- Standard configuration Attachment: 1) external YH25-3 (8Ω 25W) horn speakers for external regional radio call. 2) each one of gooseneck microphone SED + Pedal switch TFS for the drivers to reach the broadcast and conversation through the foot operation( additional pedal switch is optional for the communication between gooseneck mircophone and other handles). 3- other optional accessories: 1) handheld microphone SS-C used for the broadcasting calling (can replace the gooseneck microphone SED + pedal switch) 2) Deskside microphone SE-C for the broadcast call / speakerphone(can replace the gooseneck microphone SED + pedal switch). 3) The alarm output control uses pedal switch TFS. 1 / 1

2 电池 交流 工作 DTDigital Intercom System Power Model:DT Major power input:ac110v / AC220V;output:DC24V,6.5A. 2. With a spare power connector can be connected to the 24V battery, battery maximum current is not less than 5A. AC priority, a main power failure, automatically switches to standby power;, automatically switch to the main power supply when the main power is restored. AC priority. Using backup battery power supply, when the battery voltage is below 20V, the system stops working, in order to protect the battery. 3. Customer configure the spare battery by themselves or authorizes the factory to configure. DT004 has no charge fucntion.. Note:Choose the proper waterproof coil specs according to the cable specs: M20X1.5 or M25X1.5. DT004.. Loudspeaker Handle Control panel diagram Volume adjustable Indoor Speaker Outdoor Speaker A working indicating lamp Thejunctioncavi V V -. Application Installation 1. Prior to installation, it is recommonded to fix the two screws at the top and than ajust the two mounting feet at the bottom according to the flatness of the mouting surface. It is recommoned to add the rubber pad to amend the flatness when installation in order to avoid the deformation of the chassis because of the unflatness of the mounting surface, moreover, affect the usage. Especially the normal close of the outdoor chassis will affect the IP protection level. 2. The system bus uses a single core no less than 1.5mm ^ 2 two-core non-shielded wire power supply and signal transmission. Under special circumstances, if use shielded wire, need shield layer to be vacant to avoid signal attenuation. 3. DT001 and DT002 has the same wiring board terminals, No. 1,3 internal parallel connectivity, No. 2,4 internal parallel connectivity. 4. DT003 wiring board is inside the metal chassis, the microphone should use shielded cable and correctly connect the shield layer, or may affect the call quality (refer to the wiring diagram). 5. DT004 power cable adapt nonpolarized design, +24 V-marked make the maintanence easily, the output is only one pair of terminals, just need an external extension to achieve multiple outputs. Working status indicator Red indicator: power supply is normal working, this indicator is lit. Green indicator: 1) handle offhook or a call; 2)Step the pedal switch of the communication of the gooseneck microphone, this light is on. Yellow broadcast Indicator: When system Broadcast, the broadcast light of all the phones flashes Use and debug instruction Broadcast function 1. Under the normal standby of the system, any of calling phone can broadcast by press the button in the middle of the handle, the indicator lights on the phone panel of all the phones in the system is lit. Meanwhile, all of the speakers (except the calling phone) broadcast. If want to communicate with a certain people, you can directly broadcast the called one. When the called hear this,he can choose the closest phone to respond by the offhook. When the calling loose the broadcast button, the conservation will be normal. After talking, onhook, restor the standby. 2. The system supports up to tripartite online at the same time call / broadcast, the fourth side hooks, the phone prompts busy tone,can not to join the call / broadcast. 3. The priority of broadcasting independent channel of the cab phone (gooseneck) mircrophone is unstricted. Regardless of the order of off-hook, it can reach the broadcast/calling although 3 parties are online. Channel is independent but can be a network for other 3 party online broadcasting/calling, reaching the interoperability. 4. For the driver s room station, besides reaching the broadcast, talk by the handle, the gooseneck microphone and pedal switch is convenient for the driver s foot operation. Step the switch, gooseneck microphone broadcast to the whole region, the external built speakers of driver s room and all other speakers of the phones ring. The called responds by offhooking. And step the switch to talk status, the speaker will respond the talk content. 5. The priority of one-way alarm output independent channel of the cab phone is unlimited (customized). Regardless of the off-hook order, it can achieve alarm output although 3 parties are online. 6. When the cab phone outputs the alarm ( customized), the louderspeaker inside the cab does not ring, but the loudspeaker outside the cab rings. At this time, the phone compatiable with other phones start broadcast/calling. Alarm sound does not stop. The broadcasting content and alarm output simultaneously, meet the emergency requirement. Volum adjustability 1. Remover the connection cover( see the volume adjust figure), you will see the potentiometer, adjust the volume button with a screwdriver. 2. Clockwise adjust OUTDOOR potentiometer, the sound of the speaker strengthen, the volume of the reverse direction dimish. Clockwise adjust INDOOR potentiometer, the sound of the speaker strengthen, the volume of the reverse direction dimish. 2 / 2
