The 3 Series is Cyclops entry level Insurance rated Alarm/Immobiliser. It is basically the same as the 7 series but without the transponder remote. The TX-111 remote is a simple yet practical two button design which allows the user to silent arm the alarm via the remote as well as have the optional boot pop.
The TX-111 replaces the TX-11 remote which had a tendency for the rubber buttons to split. The TX-11 case would also break if given a hard life so the TX-111 is a much welcome improvement.

P355 Remote Immobiliser (Optional alarm that uses the horn for a siren)
P375 Alarm/Immobiliser/Glass Break + Siren
P385 Alarm/Immobiliser/Glass Break + BB Siren
Options
Like the Cyclops 7 Series, the 3 Series has a variety of siren options, the P355 uses the vehicle’s horn, whereas the P375 comes with a standard siren.
The P385 has a battery back-up siren but the big weakness with the battery back-up siren is the fact that it has to be accessible for the over-ride key. This is fine if you want that 5-star box ticked for your insurance company but in reality, it offers no real added protection.

Cyclops 3 Series RRP:
P355 $440.00 Insurance Approved: AS/NZS 4601:1999. (Old 3 Star rating) Standard Withdrawn
P375 $540.00 Insurance Approved: AS/NZS 4601:1999. AS/NZS 3749.1:2003 Class B. (Old 4 Star rating) Standard Withdrawn
P385 $620.00 Insurance Approved: AS/NZS 4601:1999. AS/NZS 3749.1:2003 Class A. (Old 5 Star rating) Standard Withdrawn
Obsessive Rating: The P375 is highly recommended.
A reliable system which is easy to live with, the new TX-111 remote is simple and rugged. However, the siren on the P385 lets the Cyclops down so I’d be looking at options from Cobra or Autowatch if I was considering an alarm with a battery back-up siren.
Note: These alarms were sold under the Dynatron brand name until 2012.
P355 = Dynatron D4400, P375 = Dynatron D3600, P385 = Dynatron D3800.
