DYNATRON 7 SERIES, D7400, D7600, D7800



Cyclops Product Range

Cyclops Product Range

The 7 Series is the flagship Alarm/Immobiliser in the Dynatron/Cyclops line up. The most recent modification of the range occurred back in 2007 when Dynatron introduced the TX-90T remote leading a trend for remotes to have that original equipment look you would expect from the factory rather than the aftermarket look. As with all good ideas, it is only a matter of time before others jump on the bandwagon and as of March 2009 Mongoose have also opted for factory style remotes.

User-Friendly Technology

The thing that sets the 7 Series apart from the competition is the remote controls built-in transponder which I have always been a big fan of. Most of us who have had insurance approved alarms can testify how annoying it is for the immobiliser to kick in after that 30-40 second gap between disarming the car, loading up the boot then jumping into the driver’s seat only for the LED to start flashing once more. The 7 Series eliminates this with its transponder remote which quite simply switches off the immobiliser when it is in range of the ignition barrel the same way that a factory transponder car key works.

Dynatron/Cyclops 7 Series Range of Alarms


Dynatron/Cyclops 7 SERIES

D7400 Alarm/Immobiliser (Uses Horn for siren)
D7600 Alarm/Immobiliser/Glass Break + Siren
D7800 Alarm/Immobiliser/Glass Break + BB Siren (Not recommended)


Dynatron offers the 7 Series with a variety of siren options, the D7400 uses the vehicle’s horn. Next in the range is the D7600 which comes with an additional siren and a glass break sensor. Finally, there is the D7800 which has the Battery Back-up siren.

My pick of the Bunch has to be the D7600 which is due to its transponder remote is arguably the most practical 4 Star alarm available, the security housing for the main alarm/immobiliser module is smaller and easier to live with than the AVS or Mongoose alternatives, this makes it easier for an installer to hide.  It’s only serious competition is the Autowatch 446RiSG which lacks the transponder remote but does has a smaller alarm casing as well as the Autowatch Anti-theft guarantee.

What makes the D7600 my choice over the D7800

As a 4-star alarm system, the D7600 is hard to fault, it ticks all the right boxes as has useful features whilst remaining user-friendly. The only difference between the D7600 and the D7800 is the Battery Back-up siren and this is the very thing which lets it down!

Dynatron View

“This is a thief’s worst frustration, a siren that won’t stop even if the wires are cut or the car battery disconnected. The owner can switch off this siren with either the remote or when the battery is disconnected, one of the two security keys supplied.”

Personally, I don’t view a Siren with an over-ride key as being very effective. Don’t make the mistake of assuming that all car thieves are stupid. It is just as easy to attack an exposed siren as it is to disconnect a battery!

AVS, Mongoose, Meridian and Uniden all have the same weakness with the sirens found on their 5-star models. I long for the day when the rule book changes and we catch up with the standards set out by Thatcham


Dynatron/Cyclops 7 Series RRP:

D7400 / P755 $489.00

D7600 / P775 $580.00

D7800 / P785 $680.00 (Not recommended)

Obsessive Rating: The Transponder  remote is a winner

The D7600 is the pick of the bunch and a highly recommended  Alarm System.

The remotes are tidy and look good without having any pointless buttons, but the siren on the D7800 is disappointing when compared to those offered by Cobra and Autowatch.

    Thank you Julian for providing such a wealth of info and knowledge on car alarms on your blog and website.
    I appreciate the help and advice you have given me (thru the website and via email) to help me make an informed decision on what to get for my car.
    Obsessive is a very apt description for your website 😉
    Thanks, Natalie

    Hi Julian,

    Your review of the Dynatron D7600 is now more than 2 years old. Would you still recommend this alarm or are there newer alarm models now available that you’d recommend (from Dynatron or other brands).

    I have just bought a new car and am looking for an alarm with a transponder remote but don’t require all the bells and whistles.

    Thanks in advance,

    Hi Marty,

    Not much has changed since the review and it’s still the easiest to live with 4 star alarm available. I’d recommend reading the related blog post (see pingbacks) plus this is worth a read too: http://vehiclesecurity.co.nz/blog/can-your-remote-be-copied

    Hi Julian,

    Thanks for your feedback.

    I’ve went to book my car in for an install of the Dynatron 7600. The installer suggeted I get a Mongoose M60 installed as they were very popular and the latest Dynatrons were a bit dodgy in terms of reliability. When I told him I wanted a transponder alarm he went quiet and went to look out the back for available stock, which he now need to order in. Considering they’re running a special on Dynatron D7600’s installation this month…

    Hi Julian,

    Could you please explain further about the quote:

    “…..how annoying it is for the immobiliser to kick in after that 30-40 second gap between disarming the car, loading up the boot then jumping into the drivers seat only for the LED to start flashing once more.”

    Will this present with the 446RiSG alarm?


  11. Julian says:

    Hi Ewen,

    Yes it will.
    The immobiliser on the 446RiSG arms 45 seconds after you disarm the alarm, 9/10 times you’ll probably have started the car before this happens.

    Should the immobiliser be armed then you’ll find the LED will come on solid when the ignition is turned on. You’ll need to press the remote once more before you can start the car.

    The good thing with the 446RiSG is that it does not set the siren off like some other models (see Mongoose M60 for example) and make you feel like a clown!

    My mate bought a car and it has a back up siren fitted to it in the engine bay, and a LED on the dash. My mate didn’t get the remotes or key for this system when he purchased the car…

    What options does he have to get a remote and key?
    Or could he remove the back up siren? So he will have a little extra space in his engine bay, or will it screw his electrical in his car?

    Your system’s sound like there top quality.

  13. Julian says:

    Hi Ben,

    Silly question, but if your mate has no remote then surely the car won’t start? Unless of course he has the PIN code over-ride number!

    If the car does run it would suggest that the immobiliser has already been by-passed so getting a new remote would be pointless.

    It’s probably best for your mate to give me a call (assuming that he’s from Wellington), or to get the alarm checked by a local Dynatron dealer.

    In regards to the siren, have a read up about them here: http://vehiclesecurity.co.nz/blog/5-star-muppetry
    If there is no alarm attached to the siren then removing it won’t hurt the car.
    Note: I take no responsibility for any work carried out by other parties

    In which case you may want to find someone local to help you, unless of course you’re willing to pay for my return flight! 🙂

    Hi Julian

    I’m looking at getting the p785 installed into a 2005 toyota ipsum this Tues. Im unsure if i already have a transponder chip in the key, (i also have a factory 2 button remote glued shut thanks to the last owner and dont want to smash it open yet) and was wondering if you could advise on whether i’ll run into issues if i get two transponder systems in the same area or if there’s something i’m unaware of ? I had the p785 for 6 years in my last truck and loved the transponders auto disarm feature which is why i leaned towards this model over the autowatch 446risg. Any help or advice is greatly appreciated.

    Thanks for the informative and eye opening blog and any help in advance!


  19. Julian says:

    Hi Adam,

    I’d suggest that you opt for the P775 as the siren on the P785 is not very flash.

    If your installer is competent then they will be able to do a test to see if your car already has a factory transponder immobiliser, If they don’t know how to do this then don’t trust them with the install and find someone who knows what they are doing.

    If it does have a factory immobiliser then you should be looking at a remote upgrade alarm as it would be silly to install something that you already have!

    driver side door lock does not unlock when i deactivate alarm.
    all other features seems to work right.

    any ideas what it could be?


  21. Julian says:

    Sounds like either a fault with the driver door motor or a wiring issue.
    If you are in Wellington then feel welcome to book the car in with me to look at.
