SL150 Installation and Setup Guide

9–2

Sounder Connections and Power

The SL150 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 “Wiring without Bell

Supervision” in Figure 20 below.

The total current drawn from the alarm output and the

auxiliary power output, combined, cannot

exceed 600mA. In addition, the sounding device must be a UL Listed audible signal appliance

rated to operate in a 10.2-13.8VDC range. Example: Wheelock Signals Inc. siren model 34T-12

(provides 85dBA for NFPA 74 and Standard 985).

Non-UL Installations

The total current drawn from this output cannot exceed 2 amps. A battery must be installed

because the battery supplies this current.

Going beyond the limits indicated (2 amps) will overload the power supply, or may cause the

electronic circuit protecting the sounder output to trip.

Sounder Supervision

The SL150 can provide sounder (Bell) supervision To activate Bell supervision:

1. Cut the red Bell Supervision Jumper located above terminals 2 and 3 on the control board.

See “Wiring with Bell Supervision” in Figure 20.

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 [1] key.

4. Disconnect the battery wires from the battery terminals.

5. Unplug the AC transformer from the AC outlet.
