6. START-UP MDP
IN THE SYSTEM
6.1 After configuration is over (or configuration stage is omitted by the user), the MDP unit switches to
the detectors’ burn-in mode and signals that by means of a green power supply diode and a
message on the LCD screen.
PRE-HEATING
System starting,
Time left: 1 min 00 sec.
During pre-heating, duration of which is defined in the installer’s menu, operation points of individual
detectors need to be stabilized to operate properly. During this stage all alarm states and
emergency states are blocked.
6.2 After pre-heating the MDP switches to normal operation. The LCD screen in real time signals
statuses of inputs of detectors and alarm inputs, statuses of outputs and critical parameters of MDP
unit’s operation.
“Threshold screen” - displays information on current alarm states and emergency states of
input/outputs of the unit and information on set operation modes.
