• Installation category (also called Overvoltage
Category) specifies the level of mains voltage
surges that the equipment will be subjected to.
The category depends upon the location of the
equipment, and on any surge voltage protection
provided. Equipment in an industrial environment,
directly connected to major feeders/short branch
circuits, is subjected to Installation Category
III. If this is the case, a reduction to Installation
Category II is required. This can be achieved by
use of an insulating transformer with an earthed
screen between primary and secondary windings,
or by fitting UL listed Surge Protective Devices
(SPDs) from live to neutral and from neutral to
earth. Listed SPDs shall be designed for repeated
limiting of transient voltage surges and the
following rated operation conditions: Type 2 (SPDs
permanently connected to the power network and
intended for installation on the load side of the
service equipment); Nominal Discharge Current
(In) 20kA min. For example: FERRAZ SHAWMUT,
STT2240SPG-CN, STT2BL240SPG-CN rated
120Vac/240Vac, (In=20kA). Maximum distance
between installation and reduction is 5m.
• In the case of a 24Vac power supply, you must
provide for adequate separation from the AC
power supply line using double or reinforced
insulation between the main power supply line
and the secondary circuit.

4 Identification
4.1 Product description and type
designation
The GEKO lights the entire scene evenly, eliminating
hotspots and underexposures, for unbeatable night-
time images and secure surveillance of the area.
The high efficiency heat sink body ensures
maximum LED durability and protection against
over-temperatures, whereas the front glass, made
of special technopolymer, provides high infrared
transmittance.
The illuminators are protected against electrostatic
discharges.
The illuminator is available in versions 24Vac/12-
24Vdc or 100-240Vac with integrated power supply.
GEKO is supplied with a wall-mount bracket that
rotates horizontally and vertically.
The GEKO infrared illuminator guarantee is 5 years,
while for GEKO with the white light is 2 years.
