Select correct output with “U” and “D” keys and then with “L” and “R” keys change the manner of 
switching the output off. Manual shutdown means that the output will be switched off ONLY after 
external intervention of the user (unit reset with “OK” button). By this time, emergency state will be 
maintained ay that output, even after the event that caused the alarm had ended. 
Automatic shutdown means that the output will be switched off independently by the MDP after the 
alarm that caused the output to switch on had ended. Information about the alarm condition is indicated 
by the pulsating sound and relevant messages on the LCD screen until the user resets the MDP. 
 
2) 

Outputs On – delay

 (delay of switching the outputs off) is a time (10 sec. by default) from the 

moment the MDP registers an alarm condition at detector’s input to the moment, when the MDP 
switches appropriate outputs on depending on location of the alarm. That delay can be set within the 
range of: 1 

÷

 120 seconds 

3) 

Outputs Off – zone1 delay

 (delay of switching outputs of zone 1 off) is a time (3 sec. by default) 

from the moment of alarm decay to the moment outputs of zone 1 are switched off. That delay can be 
set within the range of: 1 sec. 

÷

 15 minutes (only when automatic shutdown of zone 1 inputs is 

selected). 
4) 

Outputs Off – zone2 delay

 (delay of switching outputs of zone 2 off) is a time (3 sec. by default) 

from the moment of alarm decay to the moment outputs of zone 2 are switched off. That delay can be 
set within the range of: 1 sec. 

÷

 15 minutes (only when automatic shutdown of zone 2 inputs is 

selected).
