If supervision is not required, the ELD can be omitted.
The
MX1
site-specific configuration must have appropriate input
supervision modes and zone mapping for these inputs to produce any
effect. There is no default action.

MX1
has two protected open collector outputs which can be used for
driving low-current loads, e.g., external buzzers or relays.
Figure 11-17 shows examples of connection to a fault buzzer and an
external relay. The maximum load current is 500mA for each output, i.e.,
54
minimum load resistance. The relay back-emf suppression diode
can be any general purpose diode such as 1N4004.
Each output can be configured for open circuit fault detection if this is
required.
The
MX1
site-specific configuration must have output logic or a zone
mapping for these outputs to operate. There is no default action.
