CHANGING INPUT SIGNAL POLARITY
The CONCOA Protocol station provides a normally ‘ON’ signal to the alarm input when
the protocol station is operating properly. If an alarm condition occurs, this signal turns
from ‘ON’ to ‘OFF’. It is possible to change how the alarm interprets the input if for
some reason the output of the equipment being monitored is configured as Normally
Open (N.O.). Under normal circumstances there should be no reason to change the input
polarity. NOTE: CHANGING THIS INPUT SIGNAL POLARITY WILL CAUSE THE
ALARM TO FUNCTION IMPROPERLY IF IT IS USED WITH A CONCOA
PROTOCOL STATION. FACTORY DEFAULT IS NORMALLY CLOSED (N.C.) .To
change the input so that an input is ‘OFF’ when there is no alarm and ‘ON’ when an
alarm occurs perform the following steps:
1.
Turn AC power switch OFF and unplug the alarm from AC power
.
2.
If the alarm is anchored to a wall remove the four screws holding it to the wall
to gain access to the back of the unit
.
3.
Separate the front and back of the unit by loosening the 4 screws located on
the rear of the enclosure
.
4.
Using Figure 9 locate SW2 switch 2 and turn it ON.
5.
Replace back cover using the previously removed screws.
6.
Re-attach the alarm to the wall using the previously removed screws.
7.
Plug the alarm back into AC power.
8.
Turn alarm ON by turn the power switch on the bottom of the alarm to the ON
position.
9.
Test unit.
