Operation continued...
Buzzer Reset Interval - 0 min or 5 min RESET (Switch 2 of DIP Switch S2)
If the switch is set in the “ON” position, then the Reset = 0 minutes
and the buzzer timer resets immediately after the door is closed. This
essentially means that there is no waiting period before you should
open the door again. The buzzer will not sound again unless the door is
opened for longer than the Door Timer Interval rotary switch setting.
If the switch is set in the “OFF” position, then the Reset = 5 minutes
and the buzzer timer will not reset until the door has been closed for
more than 5 minutes. This means that if the door has been open for
longer than the Door Timer Interval rotary switch setting and the buzzer
sounds, then closing the door will silence the buzzer BUT NOT reset the
buzzer timer. The buzzer will immediately sound if the door is opened
any time within the next 5 minutes. Each time the door is opened during
this period, a new 5 minute “count down” period is started. The Door Status LEDs will change to green once the 5
minute period has expired.
Door Timer Interval - SECONDS or MINUTES (Switch 3 of DIP Switch S2)
Normal operation is set to “OFF” - MINUTES.
For a quick condence test, this switch can be set to SECONDS by placing it to the “ON” position. This means that
the buzzer will sound after 1 to 30 seconds (depending on the rotary switch settings) rather than 1 to 30 minutes.
This switch also changes the Buzzer Reset Interval from minutes to seconds (5 min RESET now equals 5 seconds
RESET).
Operational Test - OPERATE or TEST (Switch 4 of DIP Switch S2)
Used to test all of the output combinations of the DMA-2.0.
NOTE: The test mode disables door monitoring.
1. Set DIP switch (S2) to TEST.
2. Set rotary switch (S1) to the positions in the Operational Chart below to conrm that the unit’s output matches
those listed in the table.
3. Return the unit to normal operation by setting DIP switch to OPERATE and rotary switch (S1) to its intended time.
