Unmonitored Relays
The unmonitored relay Output C is factory set as a fault
output, and Output D as a fire output. When configured
as volt-free relay outputs, the outputs are NOT power-
limited.
If these connections are to be configured as unmonitored
relays make sure that:
a. Jumper Links are set accordingly, refer to
Section 4.3.1, Jumper Link Options,
b. Correct polarity is used when terminating at the back
box, i.e. terminal 1 being normally-open (or normally-
closed) and terminal 2 being common contact.
Maintain adequate segregation from power-limited
wiring.
4.4.6 -VE Outputs
The two -VE Outputs, located at TB2 at the bottom left-
hand corner of the PCB assembly, are normally used to
provide a DC power supply for up to two relays located
externally to the panel.
When the -VE Outputs are initially connected, the default
software outputs are set as follows:
a. Output 1 - Pre-Alarm and
b. Output 2 - Plant Warning.
During commissioning these outputs can be individually
configured to become active if any fire alarm, pre-alarm,
fault or plant warning conditions occur (see Section 5,
Configuration).
4.4.7 Digital / ÜE Inputs
These inputs are located at the bottom centre of the PCB
assembly. Digital Input 1 can be configured for use as
either a Day Mode or Class Change function. To select
the required function use the ‘Digital Input 1’ menu, see
Section 5.5.11 Digital Input 1.
Digital Input 2 is currently not supported.
4.4.8 Switch Connections
KEY-SW
The Key Switch connector is a digital input on the PCB.
Operation of the key switch permits access at level 2.
Cover Switch
The input on the PCB lower edge marked COVER
SWITCH is used with the optional cover-off switch.
Removal of the cover will disable certain functions,
depending on the panel configuration.
