XA400 Siren Amplifier
Operation Guide 1. Congratulation on your new XA400 siren. Please follow the installation procedure and wiring diagram to connect both rocker switches to XA400 siren amplifier. 2. As shown in the figure below. Two rocker switches are comprised of the XA400 siren controls. As shown in the left rocker switch A, flipping to upper position generates wail siren sound. Contrarily, pushing down to lower position generates yelp siren sound.
3. Be noted, both rockers are on-off-on type of switches. At the center position if not pushed, the switch will be off. 4. The rocker in the left (A) diagram above is toggle on-offon type of switch. Whereas the rocker in the right (B) is momentary on-off-on type of switch. 5. With switch A is off, when pushing switch B to upper position, the siren generates manual siren sound. Releasing switch B to off position generates coast down sound. Pushing switch B to lower position, the siren generates air horn. 6. With switch A placed in the upper position, the siren generates wail sound. Contrarily, if switch A is placed in the lower position, the siren generates yelp sound. 7. While switch A is placed in upper (wail) position, pushing switch B to upper (man) position changes siren sound to yelp. Pushing it again to upper (man) position changes back to wail sound. 8. While switch A is placed in lower (yelp) position, pushing switch B to upper (man) position changes siren sound to pierce. Pushing it again to upper (man) position changes back to yelp sound.
9. Regardless of the status of the switch A, pushing switch B to lower (air horn) position always generates air horn sound. 10. Siren will not work if the ignition/accessory switch is turned off.

Instruction of Operation This instruction is for the person who needs to understand how to operate the Gethru Technology Model XA400 siren amplifier. The intent of the instruction is to aid in training the new operator and later to serve as a reference to the trained operator. Also, visit http://www.gethru.com/howtouseXA400.htm for more information.
SOUND HAZARDS – Your hearing and others’, in or close to your vehicle with XA400 equipped, could be damaged by the loud sound. This can occur from exposures to loud siren sounds. All sounds generated by XA400 may, in certain situations, cause permanent hearing loss. You should minimize your exposure times and wearing proper hearing protection. For hearing conservation guidance, refer to federal, state or local recommendations.
General The XA400 is an economic siren amplifier that is designed to work with the personnel of law enforcement, fire fight/rescue and EMS (Emergency Medical Service) who drives an emergency vehicle and requests the rightof-way. With easy of use, state-of-the-art and compact size of design, XA400 will contribute to minimize the detraction other than the traffic circumstance, help to pass congested traffics effectively and reduce the time of installation. XA400 siren surpasses any existing low cost siren amplifier due to its easy-to-use rocker switches. A current-sensing circuits built onto the unit eliminates the unexpected damage with speaker overload. A regular fuse of 15 amperes is also installed inside the amplifier to protect the siren system. One toggle on/off and one momentary switch controls give the user maximum flexibility to less frequent user, such as volunteers. The XA400 must be installed under the seat, in the trunk or on the dash of any vehicles with 12 volts, negative ground chassis system. Connection between the rocker switches and the amplifier is via user supplied 18~22 AWG cables (6 conductors, 4 for rocker switches and 2 for speakers) with supplied green pluggable connector. Read the XA400 wiring diagram in details to understand how to wire the rockers to the amplifier. The XA400 can drive two 11-ohm impedance (100~150 Watt) speakers. Use 16 AWG wires to directly connect
DETRACTION WARNING – If the unique combination of emergency vehicle equipments installed in your vehicle have resulted in the siren controls being installed in the location that requires the eyes of the driver detracted from the traffics or out of eye focus while using it, operate controls only while your vehicle is stopped. It is necessary to watch the traffics while in driving and recommended to control XA400 by touch only. SOUND EFFICIENCY WARNING – It may not alert everyone although XA400 is operating properly in your vehicle. People may not hear the siren sound so you MUST continue driving cautiously. Frequently inspect the speaker to ensure that it is clear of any obstruction, such as snow or mud. Improper use of the speaker or of its installation will reduce the efficiency of sound output, which results in degrading the alert effectiveness. Be also aware that the use of XA400 does not give you the right to force your way through traffic. Your siren sound, the action is requesting the right-of-way only. Gethru’s XA400 is comprised of two separated electronic devices (amplifier and rocker switches) with a cable connected between them. The amplifier box contains all intelligence to generate siren sound. Two 3 position rocker switches are included. When placed in the middle position, the switches turn off their functions. One rocker is a type of toggle on/off switch and is used for wail and yelp sound activation. The other rocker is a type of momentary switch and is used for manual siren and air
horn sound, as well as toggling to higher frequency sound if wail or yelp has been turned on. Face the amplifier from the side with label, there is one wire coming out of the amplifier that is used to control the system power on/off. See wiring diagram marked I. This wire should be connected to ignition switch with +12V (100mA maximum required) output when activation. Use the supplied spade connector to extend this wire to the ignition/accessory power output.
Operation of Rocker Switches All controls utilized during normal operation of the XA400 are located on both of the rocker switches. One is toggle-on/off type of rocker switch and the other is momentary-on/off type of rocker switch. A. Toggle on/off three position rocker switch – This switch should be wired as the wiring diagram indicated. See wiring diagram marked C, F and J. It activates wail or yelp sound by pushing the switch to the corresponding position. Leaving this switch in center will stop the siren sound immediately. B. Momentary on/off three position rocker switch – This momentary rocker serves two functions. Without wail or yelp sound turned on, this momentary rocker will activate manual siren sound (i.e. peak and hold sound) by pushing it to the upper side. It activates air horn sound by pushing it to the lower side. See wiring diagram marked D, E and J. With wail sound turned on, pushing this switch to upper position changes the sound to yelp. The upper position is the manual siren function that is labeled and activated under no sound condition. Similarly, with yelp tone turned on, pushing this switch to upper position changes to pierce. Pushing it again changes back to yelp. Due to the momentary feature of the switch, the sound after switch is pushed will stay at the promoted sound even after the user releasing the switch to the center position. On the other hand, air horn sound can be activated whenever the momentary rocker is pushed down to air horn position. With no siren sound activation, pushing this switch to upper position generates manual siren sound “Peak and Hold” as well as
“Coast Down”. Coast down sound is generated as soon as this switch is released.
Installation A. Unpacking – After unpacking the Model XA400, examine it for damage that may have occurred during transit. File a claim immediately with the carrier stating the extent of the damage if the siren has been damaged. Carefully check all envelopes, shipping labels and tags before removing or destroying them.
B. Amplifier Installation a. The XA400 amplifier is not waterproof. It must be mounted in a location that is sheltered from rain, snow, standing water, etc. It must be also installed in an adequately ventilated area. Do not install near heater ducts or under the vehicle’s hood. b. Some possible mounting locations are: in the trunk, under the rear deck, under the front seat or in the equipment cabinet. Keep in mind that the connecting cable has a limited length. c. Using the mounting holes on the amplifier as a template, scribe four drill position marks at the mounting location. Be sure that both sides of the mounting surface are clear of parts that may get damaged during drilling. d. The siren accessory kit with mounting hardware supplied provides the siren user with a choice of mounting hardware. Secure the XA400 amplifier to the mounting surface, using the mounting hardware, including lockwashers. e. See XA400 install/wiring diagram. C. Rocker Switches Installation a. Although the rocker switches can be mounted on any surface in the cab, it should be fastened in a flat surface
near the driver dashboard. The installer should also ensure that the equipment is installed only in the areas recommended by the vehicle manufacturer. Failure to observe this warning will reduce the effectiveness of some safety equipments, such as the air bag, or damage the air bag, and cause serious injury or death to you or others. b. The selected location to mount the rocker switches must not impair the driver’s ability to safely drive the vehicle as he/she operates the siren. Good visibility and free accessibility are the major concern to select the location. D. Ignition Switch Power on/off Connection a. The provision for controlling power on/off through the ignition switch is through a wire in the front of the amplifier box. It must connect to the ignition switch of your vehicle at the position which is capable of providing 12V, 100mA while ignition turns on. It’s user’s responsibility to locate the ignition switch and terminal where you should connect with. See wiring diagram mark I. E. Electrical Installation a. Be caution. Do not let any hot wire (+12V) shorts to vehicle frame. High current due shorting conductors can cause hazardous sparks resulting in electrical fires or molten metal. It is recommended that disconnect the negative cable of the battery before performing installation. b. Do not connect the XA400 system to vehicle battery until all other electrical connections are made and mounting of all components is complete. Verify the polarities of the cable once again and ensure that no short circuits exist, before connecting to the battery terminals.
c. If routing the cable requires drilling a hole in sheet metal or other material, drill a properly sized hole (e.g. 5/8”) in the material. Install a grommet (not supplied) or similar protective devices in the hole, to protect the cable from damage which sharp edges could cause. d. User-supplied 14-gauge red and black wires are required for the positive (+) and negative (-) power connections. User-supplied 22-gauge wires are required for the rocker switches connections. Wires to rocker switches are low power, low current and are protected with current limiting resistors built in the circuit board. e. To install the positive and negative power wires, strip 1/4” of insulation from the end of the wires. Then insert the wire into the quick-on connector (color in blue, supplied) and cramp securely with a proper tool. Connect the red wire to “POS +” and the black wire to the “NEG –” locations of the connectors in XA400. Connect the other ends of the wires directly to the terminals of the vehicle battery after all installation is complete. See wiring diagram marked A and B. f. In the accessory kit, the unit is supplied with a six-position, pluggable green connector to accommodate the electrical installation of the speakers and rocker switches. g. Strip and insert user supplied, 4 conductors, 22 AWG wire into the left side of the pluggable green connector and tighten the screw at the appropriate connector position. See wiring diagram marked C~F. In addition, insert the speaker wires to the rest of the connector in the right. See wiring diagram marked G and H. The following number is viewed in the order seen from the right side of connector to the left side. Speaker – XA400 is 1. designed to operate with
one or two 11-ohm impedance speaker (100~150W). Speakers are not included as part of the siren. Any 11ohm, 100~150W speaker for use with emergency vehicles may be considered to use. See wiring diagram marked G and H. 2. Yelp input – Use the 4 conductor wires mentioned earlier in g to connect it. The input wire of Yelp connects to the upper terminal of the toggle-on/off rocker. See wiring diagram marked F. 3. Air Horn input – The input wire of Air Horn connects to the upper terminal of the momentary-on/off rocker. See wiring diagram marked E. 4. Manual input – The input wire of the Manual connects to the lower terminal of the momentary-on/off rocker. See wiring diagram marked D. 5. Wail input – The input wire of Wail connects to the lower terminal of the toggle-on/off rocker. See wiring diagram marked C. This completes the wiring for the green six-position connector. h. Connect the center terminals together of both rocker switches to battery negative terminal or chassis ground. See wiring diagram marked J. i. Plug the six-position connector into the mating connector in the unit, and apply pressure until it locks into place. j. Ensure that there are no loose wire strands or other bare wire that may cause a short circuit. All wires must be protected from any sharp edges that could eventually cut through the insulation. Also use an ohmmeter to verify that a short circuit does not exist between the positive (+) leads and the vehicles chassis. k. Perform visual check of all connections and wiring cables once more, before connecting the red wire to the positive (+) terminal and black wire to the negative (-) terminal of the battery. See wiring diagram marked A and B.
Testing After Installation After installation, test all the functions of XA400 to ensure that it is operating properly. All effective sirens and horns produce loud sounds (120 dB) that may cause permanent hearing loss. Always minimize your exposure to siren sound and wear hearing protection. After installation and testing is complete. Provide a copy of this manual to all operating personnel.
