Building A Long-Range Wireless Perimeter Sensor

When you have a very long perimeter, there’s a great temptation to protect it – that’s what I’m going to do in a 2-part series - this is more a solution I'm trying to put together, rather than a sensor.

Building A Long-Range Wireless Perimeter Sensor – When you have a very long perimeter, there’s a great temptation to protect it – that’s what I’m going to do in a 2-part series – this is more a solution I’m trying to put together, rather than a sensor. 

My sensor is Bosch’s tried and tested DS720i long-range Tritech. Right up front, the Tritech is not an external unit, but having seen the unit performing happily in many dusty semi-industrial applications, we’ve decided to go with it, in considerable part thanks to its huge range.

Opening the DS720i I can see there’s no seal between the housing and the cover – I’m going to need make sure I have protection  – either under a deep roof line – I have plenty of options there – or in a custom-made housing.  

The system I’m linking the sensor into is the AJAX system installed in a rural location that regular SEN readers have read about here (more on that system coming). 

To get the Bosch DS720i talking to the AJAX hub, I’m connecting it to the AJAX integration module – at least I’m hoping to – much is going to depend on whether the voltage supplied by the integration module is sufficient for the needs of this big sensor and if not, I’m going to need to come up with fresh options.

This module is a bare board powered by 3 batteries. The module supports remote sensors via DC in and out; there’s a pair of alarm contacts and a pair of tamper contacts.

Because the integration module is meant to sit inside the sensor and this sensor is full of mirror optics, I’m going to need to employ an external housing  – I’ve got an externally rated poly housing I can use for that job – the only modification required will be drilling out a cable entry.

I’m a bit nervous about power demand but we’ll connect the sensor up and see how we go.

You can find out about the Bosch DS720i here, the AJAX integration module here, and please don’t send me the power specifications because I’m slapping myself with them right now…

You can read more about alarms on SEN news here.
