PK-2 (50mm diameter disc-shaped tag with a hole in center)
Any of the transponders listed above can be used with PATROL reader as checkpoint, guard ID
cards or special cards. Transponders are different in shape, size, mechanical resilience and the
reading distance. For guards identifiers the best choice are ISO card or key fobs, but as checkpoints
the PK-3 and PK-2 are recommended.
Note: None type of the proximity tags can be installed behind metal sheet or structure.
PK-3 checkpoint
Checkpoint in a plastic case of high mechanical resilience. Allows for sticking a self-adhesive label
with checkpoint’s name or number. In case of installation on metal surfaces it is recommended to
put a non-metallic spacer under the checkpoint (e.g. perspex, plaster cardboard), which should be
at least 10mm thick. When installed direct on metal reading range will be significantly reduced
however still it will be acceptable for PATROL II reader. PK-3 can be located both indoor and
outdoor without additional protections.

Note : Mounting PK-3 on metal surface reduces its reading range of about 30-50% .
PK-2 checkpoint
Plastic disc 50mm diameter with a hole allowing for fixing it to the surface with a screw. It can also
be hidden inside a wall (under the plaster) or under a thin non-metallic barrier (e.g. under the glass
or a plaster cardboard). In case of installation on metal surfaces it is obligatory to put a non-
metallic spacer under the checkpoint min. 10mm thick. PK-2 can be installed indoor location only.
