Savi Tag ST-696-001 ISO Container Door Tag with GPRS/GPS and Sensors Installation Guide

Intrusion Detection Sensors

The ST-696-001 tags include door and light sensors. The door sensor monitors the amount of pressure

between the door and the device. If the door is open and the device has not been electronically unsealed, the

device sends a message to the monitoring software indicating that the device has been tampered. It also

writes the time and date of the tamper to an event log. The device also includes a light sensor that triggers an

alarm if light is detected inside the container.

Environmental Sensors

The environmental sensors on the ST-696-001 tags monitor the temperature and humidity within the

container. You can set the maximum and minimum values, and if the temperature or humidity rises above or

falls below this range, the device writes the time and date of the breach to the event log. For example, if you

are shipping a product that needs to be kept at temperatures between x and y degrees, you can set the ST-

696-001 tag to record the date and time whenever the temperature breaches the maximum or minimum value.

Tamper-Protection Plate

The tamper-protection plate’s right angle flaps are bent to extend and protect the gap behind the plate as well

as the tag plate. This plate prevents anyone from inserting a foreign object in an attempt to hold the tag plate in

the closed position.

RFID Communication Module

The communication module is positioned on the outside of the container and operates at 433 MHz. This

enables the Savi Tag ST-696-001 to communicate back to the Savi network with excellent RF performance

in both heavy metal and non line-of-sight environments.

GPS/GPRS Communication Modules

The GPS receiver communication module is positioned on the outside of the container and it periodically

turns on to acquire the location information which gets logged and subsequently reported through GPRS

module to the application. The GPRS modem is a quad band radio that support worldwide deployment on

GSM/GPRS cellular networks.
