1. Introduction
1.1 The high powered contact operated UHF transmitter has been designed to operate
in conjunction with the EMS IRIS 7256 and 7703 radio receivers. The transmitter
unit is a 12 volt operated device and comprises of a 500mW transmitter, fitted with
an additional printed circuit board with eight opto isolated inputs. The transmitter
only uses four of these opto isolated inputs; these are inputs 1, 2, 7 and 8. These
inputs when activated transmit fixed events. Input 1 when activated will transmit
an alarm event, input 2 will transmit a local event, input 7 will transmit a low
battery event and input 8 will transmit a tamper event. The transmitter can be
programmed into the IRIS receiver therefore allowing individual identification via
text descriptions. The transmitter can also be programmed into the 7703 receiver
giving LED indication of an alarm event. The inputs themselves can also be
programmed to operate either normally open or normally closed. The IRIS receiver
is capable of having a maximum of 256 transmitters in total added, whist the 7703
receiver is capable of having a maximum of 48 transmitters in total added.
1.2 As each input is opto isolated, a negative is required to be applied to one side of the
input. To trigger the input, a positive voltage should be applied if the contact is
programmed as normally open or removed if normally closed (see Figure 4, on page
20, for full wiring details). The unit when supplied will have the negatives of the
inputs pre-wired and the units tamper switch will also be pre-wired with both
positive and negative connections taken to the tamper input (input 8). On an input
activation a signal will be transmitted to an IRIS receiver and displayed in the
format programmed i.e Alarm: Zone Area 1 for an input 1 activation with the text
description of the transmitter programmed as Zone Area 1. If a 7703 receiver was
being used on activating input 1, the red Alarm LED would illuminate to give a
visual indication.
2. Tools & Test Equipment
2.1 Only standard hand tools are required to install the transmitter unit. The transmitter
is supplied with the inputs factory set as follows:-
INPUT NUMBER TYPE INPUT
ORIENTATION
1 Alarm Normally Open
2 Local Normally Open
3 Not Used N/A
4 Not Used N/A
5 Not Used N/A
6 Not Used N/A
7 Low Battery Normally Open
8 Tamper Normally Closed
If an inputs orientation requires alteration, Windows HyperTerminal with a serial a lead
will be required.

3. Equipment Required:
7940 Contact Operated Transmitter
7256 IRIS Receiver with standard 7200 software or 7703 Receiver
Power Supply Units
Windows HyperTerminal with serial lead if programming changes
are required.
3.1 Remote devices and high gain aerials may also be required for range extension,
depending upon the customer’s specification and requirements. Please note both
the contact operated transmitter and the IRIS receiver will require an external
power supply, whilst the 7703 receiver is available with a built in power supply
part number 7703/P. Figure 1 shows a typical IRIS radio system, whilst Figure 2
shows an alternative system using a Single Channel 7703 Receiver:-

5. Transmitter Programming
5.1 The transmitter unit has the facility of changing it’s inputs orientation and also the
unique identity code for the transmitter can be programmed. The settings for the
transmitter are as follows with the menu commands required shown in brackets:-
Inputs unique identification code (ID). Orientation of the input to normally open
or normally closed (CON). A full explanation of the input settings and the
operation of the inputs is described in more detail in the following paragraphs
under their menu commands headings.
5.2 To allow access into the programming menu the computer should be set up with
Windows HyperTerminal as follows:-
PLEASE NOTE: Examples shown below are from Windows XP. Other
versions of Windows may vary.
To start a new HyperTerminal session, click on the ‘Start’ button.
Then select ‘Programs’ and then ‘Accessories’.
Now select ‘Communications’, then ‘HyperTerminal’.
You will then be presented with the following screen: -
