This battery powered GSM alarm unit can monitor up to 4 digital or analogue inputs ( 4-20mA or 0-10V ) and send SMS text messages at preset intervals or on alarm. It is able to power 4-20mA devices, and is therefore ideal for monitoring, pressure, level, temperature, humidity etc. Each of the 4 inputs can be individually setup for a digital input, or analogue input with custom scaling for the process range.
New battery powered remotely programmable GSM/GPRS/SMS telemetry unit with 4 inputs (configurable to be analogue or digital) that can send alarm messages directly to your mobile phone by text message, report periodically to a mobile phone, or our internet server, or both.
Utilising the latest microprocessor technology coupled with state of the art GSM engineering, the new OmniText SMS Alarm Unit provides the most economical solution for remote telemetry with the added advantage of being self powered, to ease installation and maintenance.
The use of GSM (mobile phone) as the means of communications means there is no need to install a phone line, making the system flexible, portable and removes the need for customer interaction. Information and alarms can be sent by text message, gsm data call or by GPRS and viewed on either your mobile phone or on the internet via a secure username and password.
The unit can be programmed locally or remotely. When local the user has a series of pushbuttons and an LCD display making the process very quick and easy - there is little training involved.

Modes of operation Normally the unit will be ‘asleep’ with just the processor running. The Processor will wake up various components as and when required. For example, the processor will provide an excitation voltage of 21 volts to sensors before taking a reading – the length of time the processor gives for a sensor to settle to an accurate reading is configurable. The processor will also provide a wetting voltage of 3.6 volts for digital signals as and when required. When the OmniText unit needs to communicate over the mobile phone network it will power up the GSM module and communicate with it as required. Whilst the modem is powered up it can also receive messages for changes in configuration. The LCD display shows the actions the OmniText is performing.
The OmniText will send text messages to your mobile phone or can report to an internet based data presentation and alarm handling ‘gateway.’ Units can send messages periodically and/or on alarm. The OmniText is GPRS capable.
Power Consumption The integral battery has a capacity of 14.5 AH @ 3.6 volts. In sleep mode the OmniText draws a miserly 50 microamps. Performing additional functions, such as powering up a transducer, will drain the battery. Normally the biggest drain is powering up the GSM modem.
Configuration The OmniText can be remotely programmed by sending text messages, from either a mobile phone or from a pc with a gsm modem attached. The OmniText will only receive the configuration messages when the GSM module is powered up. There is a free of charge windows based configuration tool available to simplify this process. You can also use the pushbuttons to change certain parameters, such as alarm thresholds and analogue scaling factors, locally.
Excitation The OmniText will power the sensors normally with 21 Vdc or 3.6 Vdc at a maximum of 200 mA.
Inputs The 4 inputs are individually configurable to be 0-10 volts or 4-20mA. To configure the inputs you must adjust both the DIL switch on the unit and the configuration. For digital inputs set the system as 0-10 volts.
Quick and Easy Installation The pushbuttons allow easy navigation of the menu system, so you can view the phonebook, the signal strength, the input values, the scaling and the alarm settings.
