Disabling the Audible Alarm
The Multi-Station Remote Alarm is factory set to allow the audible alarm to sound. To silence this alarm:
1. Make sure AC power is OFF and unplug the Power cord from the Remote Alarm.
2. It is best to set the unit on a flat surface. With the Alarm placed so that the Input/Output connectors
are facing towards you, unscrew the four (4) screws that hold the cover on. They are retained in the
cover so there is no need to remove them completely.
3. Carefully lift the cover. There are two cables that connect the cover to the base of the unit. Without
unplugging these cables, carefully set the cover back enough to gain access to the DIP switches located
inside in the upper left hand corner
4. Locate the DIP switches and then using a stylus or small screwdriver, close (turn on) the DIP switch for
the Audible Alarm Silence (DIP switch 6). Refer to Figure 8 to select the correct DIP switch.
5. Place the cover back on the base. Be careful not to pinch the cables coming from the cover. Tighten
the screws.
6. Reconnect the power cord and plug unit in.
Selecting Normally Open or Normally closed pressure switches
The Multi-Station Remote Alarm can be configured to recognize either a normally open or a normally closed
pressure switch. The factory default is normally open. This is defined as the state of the switch when the needle
of the gauge is at 0 pressure. To change this from normally open to normally closed:
1. Make sure AC power is OFF and unplug the Power cord from the Remote Alarm.
2. It is best to set the unit on a flat surface. With the Alarm placed so that the Input/Output connectors
are facing towards you, unscrew the four (4) screws that hold the cover on. They are retained in the
cover so there is no need to remove them completely.

4. Locate the DIP switches and then using a stylus or small screwdriver, close (turn on) the DIP switch for
the Pressure Switch Type (DIP switch 5). Refer to Figure 8 to select the correct DIP switch.
5. Place the cover back on the base. Be careful not to pinch the cables coming from the cover. Tighten
the screws.
6. Reconnect the power cord and plug unit in.
TEST MODE
The Multi-Station Remote Alarm has a Self-Test Mode. In this mode the status indicator lights, Output Relays,
audible alarm, and Serial Port are exercised. The test sequence involves individually lighting each of the eight (8)
status indicator lights, first in red then in green. Each light stays lit for approximately 2 seconds. This is followed
by individually activating each of the five (5) Output Relays. The relays stay on for approximately 4 seconds. After
the relays have been activated, the audible alarm is turned ON. Finally, the Serial Port sends out a code (02h, AAh,
03h). When the test sequence is complete the unit returns to normal operation.
This test mode can be a useful tool in determining where a problem exists in the system.
