Sentinel
Alarm with and without output relay

Sentinel 1
The Sentinel 1 alarm is a device developed for use together with autoclave or similar systems in order to signal a lack of or excess of water.
The device is powered by the main power supply but is also able to operate without power as it is possible to be fitted with a rechargeable battery.

Sentinel 2
The Sentinel 2 device is also fitted with an output relay with free contacts, with which it is possible to activate an alarm signal.
The output relay works only when it is powered by the main power supply.
