Vista-15 Using External Sounder Sounder Connections and Power

Vista-15
Using External Sounder
Sounder Connections and Power
The VISTA-15/VISTA-15CN provides a 12VDC output, which can power external alarm
sounders (bells or sirens; see table of compatible sounders on previous page). This output will
activate a sounder when an alarm occurs.
Make connections to alarm output terminals 3 (+) and 4 (–). See Figure 17 below.
Sounder Supervision
The VISTA-15/VISTA-15CN contains a sounder (Bell) supervision option. To activate the Bell
supervision option:
1. Cut the red Bell Supervision Jumper located above terminals 2 and 3 on the control board.
See Figure 18.
2. Connect a 2k ohm resistor across the terminals of the last sounding device.
Testing the Sounder
After you install the sounder, test the security system carefully, as follows:
1. Connect the battery wires from the control board to the battery, observing correct polarity.
2. Enter the Installer code (4112) and press the TEST (5) key on the keypad.
The external sounder should sound for 1 second if the sounder is working and proper
connections have been made. Note that if the backup battery is discharged, the sounder
will not turn on.
3. To turn off the Test mode, enter the Installer code (4112) and press the OFF key.
4. Disconnect the battery wires from the battery terminals.
5. Unplug the AC transformer from the AC outlet.
