Vigilant MX1 - General Purpose Outputs; SGD or Brigade Relay Interface

Installation Guide MX1 Fire Alarm System (NZ)
LT0360 ISSUE 2.43 29 NOVEMBER 2017 PAGE 11
General Purpose Outputs (OUT1, OUT2)
MX1 has two protected open collector outputs which can be
used for driving small loads, e.g., external buzzers or relays.
Figure 14 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 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 must be configured with user logic or a zone
mapping for these outputs to produce any effect. There is
no default action.
