Finsihed install T-2200 to my bike, with ~2Km (!) 2-way alert. It is going to be a looong read, grab a drink and enjoy.

Super Long Range 2-ways T-2200 Alarm System
Most of the 2-way alarm systems on the market use FM frequency to communicate between the transceiver units. My experiences told me that the range isn't great, especially inside a building. Metal building structure will block out most of the RF, and in most cases it will be out of range in downtown area, campus, and even my apartment. So I decided to build a long range 2-way alarm system using GMRS, and its range can be up to 8km in open area, or around 2km in downtown area. The range of the alarm system will never be a problem again, but for me getting to my bike when the siren sounds, it's something I need to work on later.
The easiest way to use a GMRS radio as 2-way alarm system is to buy one with VOX function, put it in the bike, done. When your siren sounds, it will TX the noise to your other radio, work just like a baby monitor, but at much longer range and you can carry the radio to Starbucks. 4 AAA should last you 24hr with battery-save mode, or buy one with 12V adapter available and rechargeable battery. (They draw ~5mA standby.)
Being a geek, I never follow the KISS principal. I modified the radio and used its wonderful Page/Call* function instead. My bike will only page me if the alarm is triggered, not with any other instances.
(*Page/Call function - when you pressed the Call key on the radio, it will transmit a Call Alert Tone to all other GMRS with the same channel.)
An alarm is all I need now. After many research, Talon T-2200 is the best option. It is well priced and has some cool options which I will discuss later. Best of all, Brad (the President of Talon) provides excellent service and support. I emailed him some questions before I order it, he replied me within hours, and it was the long weekend as well.
Now, for those of you who want to know more about this project to protect your bike, or stealing others, here is what I've done. Again, this may violate Canada Radio Frequency Interference Regulations and local laws. So, do it at your own risk!
Talon T-2200 remote control motorcycle alarm system (www.talonalarms.com/t2200/)
GMRS 2-ways radio (Uniden TR620, $15 @ London Drug )
Multi-use DC adapter ($11 @ Canadian Tire)
5A Relay (parts # 2750249, $4 @ thesourcecc.com)
Diode (parts # 2761144, $2 @ thesourcecc.com)
Chainsaw (the biggest one I can run 5k with)
Using T-2200 White (+) Turn Signal Outputs to close the Page function circuit isolated by a N.O. Relay. A diode is added to prevent reverse feedback by signal light during riding.
(for those geek 100% understood the above statements, stop reading and start get your hands dirty.)
(+) Well priced;
(+) Compact size, both module and keychain;
(+) Weatherproof design;
(+) High quality wires, no need for shielding;
(+) Super easy to install, incl all needed parts.
(+) Lots of features;
(+) Excellent customer support;
(-) Key must be in to adjust sensitivity;
(I am working on using trunk release w/ latching relay to solve this problem.)
(-) Grey LCD wire on the short side.
Talon T-2200 is a very well built unit. The module is protected by a durable plastic case, and the keychains are compact and cool looking. Both shock sensor and tilt sensor do their job perfectly. Great product.
(+) Cheapest GMRS I can find; separated Call button; small size.
(-) Draw 6mA even it turned OFF / 20mA ON; 2km range; no battery-save mode; no privacy code; no vibrate.
I am buying a new radio later, this cheap one is just a ginnie pig for the project.
Set up the T-2200, and test it out for a few minutes. Make sure you cover the siren with something, don't want you neighbors come knocking on you door.
Now with a good understanding how the alarm works, time to do the real work. First cut one of the White wire to desire length and solder the diode to it. The diode MUST be connected in the direction as shown, the stripe mark is on the Signal light side. Cover it with heat shrink tube.
Install the alarm to the bike. No, I am no telling you where I put it.
Time to open up the Radio. The radio for this project should have a separate Call button, some higher end model may use the Call button as Weather channel as well. When you press the Call button, it creates a shorts between the two “E” shaped circuits.
I solder a wire on each “E”, when these 2 wires connect to each other, the radio will start paging. The width of the “E” is ~0.5mm. Soldering the wires to the surface circuit is the toughest part of this project, take your time. I first used a solid core wire, but the vibration broke the joint.
I then used the tiny wires from the inside of a USB cable.
Use a multimeter to confirm the soldering job is clean, and tape it up to reduce stress on the solder joint. Time for a beer.
A Relay is used to close the Call button circuit, I could use the 30A relay included with the alarm. However, a 5A relay is a better choice, since it will react faster. A solid state relay is even better, but it is out of my budget. Solder the two tiny paging wires to the “Com” and “NO” pin. Afterwards, solder a Ground wire and a Signal wire to the “Coil” pins, one wire in each. When there is a current on the Signal wire, the relay will close the paging wires, thus the radio will start paging.
The Multi-use DC adapter will be the power supply for the radio. Just connect the input to the battery with a 2A fuse in between, and output (4.5v) to the radio.
**tiny green & white -- paging wires
**tiny red & black (right side) -- 4.5V & Ground
**Red, Black, and White (left side) -- 12V, Ground, Radio Signal input
After all these soldering jobs, put the radio, relay and power supply inside a small case as the housing. There are really only 3 wires to connect: 12V, Ground, and Radio Signal input. To complete the whole two-way system, connect the Radio Signal input wire in between the Diode and T-2200. Done.
Now, every time the Signal lights flash because of the alarm, the Radio will page me. I like this setup much more than just VOX, it's more effective and accurate. Some high end Radio models offer the vibration option, just like cellphones, can alert you without worrying the paging sound.
Most 2-ways alarm system on the market cost ~$400, mine is ONLY under $200 with 10x the range. Time for another beer.
For those of you that are still reading this, I am sure you want to protect your bike badly, let me share some ideas I have for my next project.
When I first order the T-2200, I thought actuator is included. I was going to use it to a trigger Bear Attack Deterrent Spray. Just in case in the event of a bear comes up to my bike, and don't back off by the siren, the spray will be useful to keep it away. A word of warning though, NEVER transport the bike w/ the spray inside a Cargo Van, if the spray accidentally fires while driving, it is very dangerous.
The Pink(-) trigger wire is also very useful. If you connect the Pink wire to the Ground (-), the alarm will trigger instantly. XScargo sell a 4 pc door alarm for $10. Rip it open and connect the Pink wire to one end of the magnetic switch, and another to Ground. Once magnetic tankbag is removed for the switch, it will trigger the alarm.
I have this setup for a week now, works good, the bike battery can handle the load. If you guys have any question, just ask.
