Monnit ALTA wireless control units contain two separate relay switches allowing for individual control through the iMonnit online sensors portal. The ALTA control unit relays can be switched on/off manually through the software or automatically by any wireless sensor notification assigned to a single sensor or group of sensors when a specified condition is detected.
Principle of Operation
The ALTA control unit has two separate relays that can be toggled on/off at will by either: (a) the iMon-nit.com web portal; (b) any device that triggers a notification on the same network.
Four LED indicators let the user know if the device is powered on, communicating with the online system and the status of each relay.
The user can manually turn a relay on or off through the iMonnit software. Manual changes are either: (a) temporary based on a set duration (ex. activate the relay for 10 minutes then return to the default state); (b) perpetuated indefinitely until overridden.
Each of the units two relays can also be controlled automatically by any wireless sensor or group of sensors. Automatic relay switching can be triggered by setting the control parameters in a sensor notification from the system. The user can set the default state of each relay to on or off and user defined messages from sensors will cause the relay unit to switch to the non-default state. The relay switches back to its default state when the condition is no longer met.
Example Use: If a water sensor detects water at a certain level in a sump pit, the relay will switch ON, activating the pump. When water is no longer detected, the relay will switch OFF, deactivating the pump motor.
