Monitored Input: MI1+, MI1-, SCRN
Maximum Voltage at contacts, 3.3 Volts. Maximum current 10mA.
Monitored Input 1 may be configured to monitor for open and short circuit faults using a 3k3 EOL
resistor and to activate an alarm using a 680Ω ‘firing’ resistor. It may be configured from the engineer
menu to the following options:
Monitored Input 1 is an ancillary function and is not required by EN 54-2.
Programmable Inputs 1 and 2:
Maximum Voltage at contacts, 3.3 Volts. Maximum current 10mA.
Inputs 1-2 are Un-monitored and require a normally closed contact to operate. They may be configured
from the engineer menu to the following options:
Programmable Inputs 1 & 2 are ancillary functions and are not required by EN 54-2
