5.1 ELECTRICAL INSTALLATION
5.1.1 General Information
To comply with Underwriter Laboratories (UL) and Canadian Standards Association (CSA) certification,
route signal leads and power cables in earthed (grounded), flexible metal conduit.
▪Instruments not fitted with the optional internal on/off switch and fuse must have a
disconnecting device such as a switch or circuit breaker conforming to local safety standards
fitted to the final installation. It must be fitted in close proximity to the instrument within easy
reach of the operator and must be marked clearly as the disconnection device for the
instrument.
▪Remove all power from supply, relay and any powered control circuits and high common
mode voltages before accessing or making any connections.
▪Use cable appropriate for the load currents. The terminals accept cables up to 14AWG
(2.5mm1).
▪The instrument and all inputs and outputs conform to Mains Power Input Insulation Category
ll.
▪All connections to secondary circuits must have basic insulation.
▪After installation, there must be no access to live parts e.g. terminals.
▪Terminals for external circuits are for use only with equipment with no accessible live parts.
▪If the instrument is used in a manner not specified by the Company, the protection provided
by the equipment may be impaired.
▪All equipment connected to the instrument's terminals must comply with local safety
standards (IEC 60950, EN601010-1).
NOTE:
In order to ensure maximum GSM Dialer performance, proper wiring installation practices must be
followed. Failure to do so can result in a range of problems, from loss of configuration to component
failure, caused by transmitted or radiated electrical noise. Proper consideration must be given to local
noise sources and appropriate suppression steps taken to minimize any potential problems. Among
the most common sources of noise are: Relays, SCRs, valve solenoids, electric motors, power line
disturbance, wire-to-wire coupling, electrostatic discharge (ESD) and radio-frequency interference
(RFI).
To achieve the best results, the following notes should be considered:
1. Signal input wiring should be twisted pairs/triplets etc. The conductors should be stranded
rather than solid in construction. All signal wiring should use ground-shielded wires, or be
routed through grounded conduit to minimize the effects of RFI and ESD.
2. Special care should be taken when wiring to relay or solenoid coils, as large transients are
produced when coils (or any other inductive loads like motors or arc welding equipment’s etc.)
are switched. This problem can be eliminated by the use of suitable suppression devices across
the coil. Coil transients can also be transmitted through the air, so the recorder itself should
be mounted as far as possible from power control devices and/or wiring.

5-8 G-Tek Corporation
Installation
3. When line power is poorly regulated and / or subject to voltage surges or transients,
consideration should be given to the use of a line conditioning/transient suppressing line
power regulator. Process control motors, valves, relays and heaters should not be connected
to the same power lines that are used for instrumentation.
4. All local electrical codes of practice must be followed when installing any instrumentation.
5.1.2 Mains Supply Connection
The connection for Mains supply is shown in figure-9. As per figure one end of the adaptor connected
to mains connector else other option for power supply through 2pin relimate female. Ensure that the
end of adaptor/ connector is fully inserted into the mains connector and no loose/poor connection.
Figure 4 Mains supply connection
5.1.3 Alert Inputs
Total 5 alert inputs are available. For connection, Pitch of male relimate is 2.54 mm and 10pin Stranded
wire recommended for female relimate. Remaining two pins are NC. Alert priority 5 input is the highest
priority input and alert priority input 1 is the lowest priority input.

Operation
6OPERATION
GSM Dialer is an automated mobile equipment. It is a similar to our mobile devices.
GSM Dialer is a unique Facility to our customer that provides real time alert of the device activity .This
Device maintains the record of Phone numbers and also differentiates the admin and operator
controls.
At power up GSM internally take 12-15 sec for Synchronize GSM, get GSM SIM Status, and get GSM
IMEI Number Network Registration and phone number validation. If the SIM Card is not registered the
Network LED will be
blinking at 1 sec. This
signals a registration
failure or a network
failure. Also the Status
LED turns RED from
GREEN in case of any
ERROR/FAILURE in the
GSM else it turns GREEN
means system perfectly
working.
GSM Dialer observes the
activity of connected Device and based on the activity if a special event occurred then it will notify all
the stored numbers with admin and other operators with a specifying the event alert.
6.1 ALERT MESSAGE AND CALL BASED ON PRIORITY
GSM Dialer notify alert with Text message then after notify by voice call. Alert message string and alert
priority set by user using PC application. Message and voice call sending restriction is possible for
particular contact number, also one can change the alert message string using PC Application for more
detail refer GSM view log manual. For any change in voice call playback refer voice call playback
selection section.
Network failure or out of coverage or in any other failure condition, GSM try three time to connect
that number. Still alert was not sent in that case it report as failure in log report that report of message
and call success / failure download in pc application.
Important thing in GSM calling that user miss alert call in any case GSM dialer call 4 times to same
number still not receive than it report failure once it received it consider as successful alert indication.
GSM dialer specially designed in such way that alert will service based on set priority. In case, during
low priority services if high priority alert will come it will terminate the low priority and start sending
alert messages and call for high priority alert.
During high priority services if any low priority will come it accepts and further process after
completion of high priority alert. While GSM processing and same alert will come continuously it
accept only one at time.

Operation
6.2 PROCESS ARMING-DISARMING AND PARTIAL DISARMING:
GSM Dialer support arming, Disarming, and partial disarming using special command send by admin.
That command is sent in text message whose command format is shown in figure 9 that message GSM
accept if command sent by only admin.
If system under disarming mode it stop accepting any
upcoming alert until it get arm command. If GSM accept
arming command it start accepting upcoming alerts and also
starts servicing if pending any alert(s).
Partial disarming is one of the best remotely automated
disarming feature. Admin send partial disarm command with
defined time duration in minutes, system get disarm according
to time request from admin then automatic arm. If any
pending alerts remains before acceptation of partial disarm
command it automatic starts services pending work once it
come back in arm mode.
The important thing is it accept arming-disarming and partial
disarming request only if request sent from selected three
admin number and after acceptation of request it give
response back through message string with specifying
requested number.

8.3 COMMUNICATION TYPE
Our GSM Dialer uses two protocol to communicate with the MODBUS.
8.3.1 USB
In order to connect GSM dialer as USB communication mode bellow mentioned procedure.
In order to operate the GSM Dialer in this mode connect UBS cable mini in the USB slot of the GSM
dialer as shown in Installation section and connect the other end of the cable to the computer.
USB has the following key features:
Single connector type: USB replaces all the different legacy connectors with one well-defined,
standardized USB connector for all USB peripheral devices, eliminating the need for different cables
and connectors and thus simplifying the design of the USB devices. So all USB devices can be
connected directly to a standard USB port on a computer.
Hot-swappable: USB devices can be safely plugged and unplugged as needed while the computer is
running. So there is no need to reboot.
Plug and Play: Operating system software automatically identifies, configures, and loads the
appropriate device driver when a user connects a USB device.
Expandability: Up to 127 different peripheral devices may theoretically be connected to a single bus
at one time.
Power supplied from the bus: USB distributes the power to all connected devices eliminating the need
for external power source for low-power devices. High-power devices can still require their own local
power supply. USB also supports power saving suspend/resume modes.
USB device communication is based on pipes (logical channels). A pipe
is a connection from the host controller to a logical entity, found on a
device, and named an endpoint. Because pipes correspond 1-to-1 to
endpoints, the terms are sometimes used interchangeably. A USB
device could have up to 32 endpoints (16 IN, 16 OUT), though it's rare
to have so many. An endpoint is defined and numbered by the device
during initialization (the period after physical connection called
"enumeration") and so is relatively permanent, whereas a pipe may be
opened and closed.
Figure 8 USB endpoints actually reside on the
connected device
