Firmadoor & ATA Compatibility With Elsema 27.145Mhz System

WE SEND THESE REMOTES ALL OVER AUSTRALIA

ELSEMA KEY 301 - 302 - 302DA - 304


Elsema used radical & state of the art technology to bring the remote security aspect of gate & garage door control into the 20th century.  At that time you could choose between 3 uncoded & unprotected frequencies.Taxis, police cars & planes could open you door as they went past.

Their innovation was to use 10 then later 12 x 2 position switches to form a digital code which when the receiver was set to the same switch sequence would activate the device.


FIRMADOOR FMT2 & ATA TXA1

Most installers will tell you this is rubbish & you need to replace the opener but:-

The story goes, Firmadoor (later to become Automatic Technology Australia - ATA) used the same system as Elsema & to get around copyrite laws reversed everything including the switch sequence.

So Firmadoor & ATA 12 switch single button remotes are 100% REVERSE compatible with ELSEMA 12 switch single button remotes. Just code backwards.

Switch 1 on the Firmadoor / ATA = Switch 12 on the Elsema
Switch 2 on the Firmadoor / ATA = Switch 11 on the Elsema
Switch 3 on the Firmadoor / ATA = Switch 10 on the Elsema

Down To 

Switch 12 on the Firmadoor / ATA = Switch 1 on the Elsema
Receivers are set with all 12 switches to match.

ATA & FIRMADOOR 27.145Mhz remotes went out of production 15 years ago, so Elsema is your only option.  For more information go to:- http://www.retro-remotes.com/elsema-remotes


Multiple Button Remotes


This is where it get complicated.  The 2 & 4 button remotes come in 2 versions 10 Switch & 12 Switch

10 Switch 2 & 4 Button - Although you can see only 10 switches there are in fact 12 switches in use.

Firmadoor / ATA Button 1 = 11 & 12 off + code set 1 to 10
Firmadoor / ATA Button 2 = 11 & 12 on + code set 1 to 10

Firmadoor / ATA Button 3 = 11 off & 12 on + code set 1 to 10
Firmadoor / ATA Button 4 = 11 on & 12 off + code set 1 to 10

The receivers are set with the full 12 switch setting to match.


Elsema uses the same system invisibly switching 11 & 12 for the four functions.  As the Firmadoor / ATA 11 & 12 are the Elsema 1 & 2 it cannot work.

Answer - You have to junk the old & re-code the devices to Elsema.
If you have 2 x garages you can use 2 x single button Elsema remotes for car 1 & car 2 loosing control over both doors.

12 Switch 2 Button - This is used on unit or townhouse complexes.

When you press button 1 Common Entry you send out a code that has the switches set 1 to 4 with 5 to 12 off & the gate receiver is set to that code so everyone can use the gate.

This leaves the balance of codes for the individual garage doors, more than enough. So when you press button 2 your garage is secure as all 12 switches come into play.

Again ELSEMA uses the same system so it cannot work as 1 to 4 on one is 9 to 12 on the other.

Answer - Fit a 2nd Elsema receiver to the gate for Elsema remotes only & re-code garage door to Elsema Key 302DA code

ATA & FIRMADOOR 27.145Mhz remotes went out of production 15 years ago, so Elsema is your only option.  For more information go to:- http://www.retro-remotes.com/elsema-remotes
