EVAC / SILENCE / RESET inputs
There are 8 monitored inputs dedicated to triggering signals for evacuation, silence and reset instructions
from the external fire detection system.
6 x EVAC in
1 x SILENCE in
1 x RESET in
Each of these 2-pin inputs has built-
in DC monitoring which requires two resistors of 4.7kΩ + 10kΩ in
order
to detect an input active/inactive state as well as a short and open fault. EOL resistors must be located
directly at the triggering output inside of the external device (i.e. fire detection system) to provide reliable
surveillance of the entire link.
EVAC / SILENCE / RESET inputs must receive an activation signal of at least 100ms in order to trigger events.
Pulses shorter than 100ms will be ignored.
System status relay outputs
There are 3 potential-free relay outputs to external devices. Each output has individual 3 pins:
normally open,
normally closed,
common.
