Description
The M1000 is an alarm panel with 10 digital inputs. Inputs from
a dry contact (normally open [NO] or normally closed [NC])
will cause the corresponding LED to flash. Simultaneously a
common alarm output and a siren output will be activated as
well as an individual output. The unit has separate indications
of first alarm, following alarms and acknowledged alarms. It
also has dedicated inputs for remote reset and blocking. The
unit can be configured for cable monitoring and monitoring of
its own supply and insulation level.
Multiple M1000 units can be interconnected to form a large
scale alarm system. In this situation functions are available
for synchronizing the flashing of the LEDs and enabling
global indication of first alarm for all connected units. Alarm
related parameters like time delays, reset functions and other
features can be configured through 18 programming switches.
The M1000 can also be configured via the RS232 interface.
A standard ANSI/VT100 terminal is used as programming
tool. The M1000 is equipped with a 2-wire RS485 interface
supporting MODBUS-RTU communication.
