LINE Alarm Module

The LARM01 Line alarm modules provides an ideal way to add alarm capability to a control system loop. It can notify people in charged through personal Line app by easy setup. The optional relays each have setpoint and deadband controls and an LED to indicate on/off relay status. Relay phasing switches individually select each relay to operate in response to increasing or decreasing input signal value. For compatibility with many systems, input levels are user selectable. The LARM01 accepts PT100, 0 to 50 mV, 0 to 100 mV, 0 to 5 Vdc.
Model : ACCUIOT-LARM01

The LINE alarm module is a compact, distributed control and signaling system. All the inputs

and outputs (I/Os) of the module are monitored by Line, SMS text messages, and email, and are

controlled by communication through the internet network.

The module is configured by means of configuration software. Every input and output can be

modified by means of user-defined parameter names and messages. A selected group of

users can be chosen from the phonebook to configure and operate the module ("active

users"), or only to receive messages ("users").

Line alarm module features:

digital output (DO), relay outputs, changeover contacts, 250 V/5 A

universal inputs (UI), which can be set by means of configuration software:

Analog input (AI), 0 to 10 V

Digital input (DI)

The module sends a previously defined message to selected persons with every defined change of state (rising or falling flank in the case of digital inputs or reaching a level in the case of analog inputs).

The outputs are switched whenever an active user sends a previously defined SMS to the alarm module.

For testing purposes, the LINE alarm module can send a text message on a regular basis, i.e. at a user-defined time. In the event of a power failure, the module still has enough energy to send an message to all active users to inform them of the power failure. It also sends an message once the power supply has been restored.
