NOTE: Connect the Digital Inputs to either a Normally Open or Normally Closed Dry
Contact. You may then individually configure these Inputs to have End-of-
line (EOL) Sensing in the Software. The ImproX I16 implements End-of-line
(EOL) Sensing where one 4.7 kilo-ohm resistor is used. Figure 1 shows the
recommended connection of the resistor for Normally Closed (NC) and
Normally Open (NO) contacts. For Normally Closed Dry Contacts, connect
the 4.7 kilo-ohm Resistor in SERIES with the contact. For Normally Open
Dry Contacts connect the Resistor in PARALLEL with the contact. Mount the
4.7 kilo-Ohm resistor as close as possible to the Dry Contact (not at the
ImproX I16) for effective End-of-line (EOL) Sensing. This method of End-of-
line (EOL) Sensing senses a “Door Closed” event. An input shorted, input
cut or door open will all yield a “Door Forced” event. That is the Software
will not distinguish between a tamper condition (cut or shorted Input) and a
normal door open event.

INSTALLATION INFORMATION
Accessories
Find the following when unpacking the Terminal:
An ImproX I16 16 Channel Input Terminal housed in a Black powder-coated
Aluminium extruded Cabinet. The Cabinet is sealed at each end with an
Aluminium End Plate, secured with 4 Allen Head Screws (M3 x 12 mm).
Two Plastic Bushing Plugs (20.6 mm).
A 2.5 mm Allen Key.
An extra Fixed Address Label.
General
Remember the following when installing the Terminal:
Communications Distance
The RS485 communications distance between the first ImproX Controller and the LAST
ImproX unit in a cable run, MUST NOT exceed 1 km (1 094 yd). Achieve this by using
good quality screened twisted pair cable, with the screen EARTHED at one end.
