Alarm Monitor M1000

SELCO Alarm Monitor M1000

The SELCO M1000 alarm monitor is a compact alarm unit, designed for demanding environments, such as marine and industrial applications. The M1000 panel features 10 digital inputs, and 10 outputs, all programmable.  Alarm related parameters, like time delays, reset functions, cable monitoring and other features can be configured easily.

The SELCO M1000 alarm monitor is easy to install and configure and can be used as a stand-alone monitoring unit, almost plug’n-play for small alarm applications. In case of many alarm points, more M1000 alarm units can easily be added to form a larger alarm monitoring system.  The M1000 alarm unit is equipped with a RS485 interface supporting MODBUS-RTU communication for connection to a master unit, such as an HMI panel.

The M1000 Alarm Monitor

The SELCO M1000 is an Alarm Monitor capable of surveying the state of up to 10 potential free contacts.

The inputs of the M1000 can be used to monitor both normally open (NO) and normally closed (NC) contacts. Each contact can be sourced to a positive or negative reference. The M1000 includes a total of 10 inputs and 10 outputs. Each input controls two bright red LEDs and an open collector output. A built-in relay provides audible alarm through control of an external siren. An input from a dry contact  will cause a corresponding LED to flash. Simultaneously a common alarm output and a siren output will be activated as well as an individual output.

The first incoming alarm is indicated with a quick flashing light, following alarms are indicated with slow flashing light. LEDs will keep flashing until the alarms are acknowledged, even though the input signal has been deactivated. Pressing the RESET pushbutton will acknowledge all new alarms whereby all flashing LEDs will change to steady light, provided that the related inputs are still active. Pressing the RESET push button will also silence the siren. The reset sequence is programmable.

With protection class IP56, the M1000 Alarm monitor is built for the toughest environments, espescially the wettest marine ones. The unit is well-proven and widely recognised by professionals world-wide and is installed in numerous applications in marine, offshore and industrial applications, ranging from applications with just a few alarm points to more than hundreds.
