CONFIGURING THE REMOTE ALARM

The Protocol Station Remote Alarm can be configured to allow connection to either Normally Open (N.O.) or

Normally Closed (N.C.) pressure switches.

Setting the Alarm for Normally Open or Normally Closed Pressure Switches

The Protocol Station Alarm is factory set to operate with Normally Open (N.O.) pressure switches. By definition,

a Normally Open (N.O.) pressure switch is one whose contacts are "open" when the pressure switch gauge

needle is below the trip point. To configure the alarm to operate with Normally Closed (N.C.) pressure switches

perform the following steps:

1. Unplug the power plug from the Remote Alarm power jack.

2. It is best to set the unit on a flat surface face down. Remove the four (4) screws that hold the back

cover on and set the cover aside.

3. Locate the 4 position DIP switch array and then using a stylus or small screwdriver, open and close the

DIP switches according to Table 5A, 5B and Figure 9.

5. Place the back cover back onto the base and tighten the screws.

6. Reconnect the power plug into the power jack and plug the unit in.
