iD Plus Marches On...

Note: From the 1st August 2010 we will no longer be stocking iD plus biscuits. We have been an active part of the iD scene since its introduction in the early nineties, and we do wish to reassure you that our Euro range of panels will continue to support iD plus technology. Whilst we will no longer be stocking the iD plus biscuits, they will still be available through the major security wholesalers.

Castle Care-Tech are pleased to announce that we are licensed users of the new iD Plus biscuits. The technology of iD has been extended, giving you the installer a much stronger and more versatile product, whilst retaining its simplicity of use and speed of installation.

Increased Area Coverage

iD plus will allow up to 30 biscuits on a total cable length of up to 400m (up from 100m), allowing you to protect a much larger area.

Lower Temperature Threshold

iD plus can operate in temperatures as low as -25C, and in temperatures as high as 70C.

Improved Biscuit Numbering

Each biscuit has clear, easily readable label, allowing quicker and easier iDentification.


iD plus biscuits are compatible with all Castle Care-Tech iD panels (except the 1700). iD Plus biscuits can be placed on the same iD lines as the old style (white) iD biscuits, but it is not recommended for best performance.

Current Product Range

Our current iD range of Euro-MERiDIAN panels are:

Euro-ONE 76: 30 iD zones wired to the endstation and 30 iD zones at a ZEM
Euro-ONE 162: 30 iD zones wired to the endstation, and 30 iD zones at each of four ZEMs
Euro-ONE 280: 30 iD zones wired to endstation, and 30 iD zones at each of three ZEMs

Typical iD Wiring Configuration

Max total cable length 400m
Max devices 30
iD wiring makes so much sense - all of the detectors can be wired to one continuous run of cable, saving the cost and time of having to wire each detector individually back to the end station.

Simple iD Wiring

Maximum Total Bus Length 400m (0.2mm2 cable)
Maximum Device Connectivity 30 biscuits/devices
Maximum Operating Temperature 70°C
Minimum Operating Temperature -20°C
Biscuit Weight 1g
Biscuit Dimensions h=53mm w=11m d=2mm (including leads)

iD PLUS marches on

Mixing iD Plus biscuits with the original white iD biscuits on the same line is not recommended for best performance.

If you are using a ZEM in iD mode, and if it is more than 10m from the endstation, it must be plugged onto a power supply (EUR-032)
