Product Information

Latest version of the Meta DefComT, we introduce the Defcom 3.1b Alarm System (Externall apperance & all connections are exactly the same as the Defcom3/T & Legos 4),  Thatcham 2 to 1 upgrade alarm system which can also be used as a stand alone motorcycle alarm system, also upgrades any motorcycle fitted with a Cat 2 immobiliser to full Thatcham Cat 1 status. Well-featured, cost effective compact design provides discreet installation and makes it ideal for all scooters and motorcycles.Also included are two fobs have been pre-coded, alarm beeps activated & the sleep timer has been extended to 20 days (more info below)

This kit includes two remote fobs pre-programmed to the alarm (including the ID'tag if chosen), the alarm is also programmed to be fully 'awake' for up to 360 hours (15 days), this means if you arm the alarm it will enter sleep mode after 20 days or if the battery falls below a set level.  The alarm will also be preprogrammed to beep when arming & disarming via the fobs. This service is included with all the Defcom3.1b's supplied by Abacus Car Alarms.

As standard & supplied by most other dealers all Defom3.1bs are preprogrammed to be awake for a maximum of 120 hours (5 Days), once 5 days have elapsed the alarm will shut down, should someone attempt to steal or move the bike the alarm will not sound. The alarm will be silent on arm/disarm.Programming the fobs must be done when powering up the alarm for the first time, if this programming period has been missed a slightly complicated proceedure will be required to code them in. The beep on arm & disarm can be programmed by the owner, however the sleep timing period can only be programmed by a dealer using special equipment.

ID Tag Option:

If choosing the ID Tag the 'Auto Arm' option above can also be added & will function seamlessly with the ID Tag (Auto-Arm option can also be added if using the standard fobs, but the alarm will need to disarmed every time you want to move or use the bike - can be put into service mode so the alarm will not interfere when servicing the vehicle), the alarm will automatically disarm when the Tag is within 10 metres of the alarm unit. Please note if the alarm is armed by pressing either the standard fob or ID tag button it will also need to be disarmed using the button, it will not automatically disarm even when using the ID Tag. When using the Tag button there is usually a 3 secound delay, this is normal, when using the Tag normally there will be no such delay, there is no delay when using the standard fobs.

The ID tag & any programmable options can only be added when ordering a new Defcom3.1b, if required at a later date the alarm unit complete with all fobs will need to be returned to us for re-programming, extra charges will be incured. The TXM252 or HPA Evo fobs can be added at any time using the 5 digit override code
