The device has four relays with normally open and normally closed contacts. The relays can be activated remotely (SMS, call or HTTP API command) or locally. For the local activation, one of the monitored parameters is assigned to the relay – alarm state of the parameter activates the relay.
TCG140 can initiate a connection (HTTP Post) to remote dedicated servers. The payload of this post is XML file, with current values of monitored parameters. The HTTP Post can be sent periodically or under alarm conditions. As an answer to the HTTP Post, an HTTP API command can be returned for relay activation or change of some settings.
In addition to the HTTP Post alert, the device can send SMS and/or e-mail as an extra alert for up to 5 SMS and e-mails recipients.
