SB4U Analog Audible Detector
Base Installation Sheet
Operation
The SB4U Analog Audible Detector Base adds an audible output
function to the listed compatible detectors. The base can operate as an
independent local alarm, or as part of a zone or system alarm with
synchronized audible output.
The output of this detector base is field-configurable for output tone
(steady or temporal) and output volume (low dBA or high dBA).
Depending on the system supporting the device loop, the base can:
• Follow the state of the device it supports
• Be controlled and configured for other operating modes through
front panel programming or the configuration utility
The base uses the same address and programming label as the
detector it supports.
Installation
Cautions
• To avoid accidental damage to the control panel, disconnect all
power before wiring the unit.
• Electrical supervision requires the wire run to be broken at each
terminal. Do not loop the signaling circuit field wires around the
terminals.
Note: Always connect the base to a continuous voltage, whether the
output tone is set to steady or temporal.
Sleeping rooms: In sleeping areas, use the high dBA output and
temporal tone settings. However, if the control panel is producing the
three-tone temporal evacuation signal, then the high dBA output and
steady tone settings are permissible.
AB4G-SB: When using the AB4G-SB box, install a reinforcing plate at
every knockout. (Reinforcing plates are included with the box.)
Remove the knockout first and then slide the reinforcing plate into the
plastic housing. After the plate is in place, install the conduit connector
and nut. See Figure 1.
Typically, the base is configured to produce a high dBA temporal tone
and is connected to a notification appliance circuit that outputs a
continuous 24 VDC signal. If the notification appliance circuit outputs a
temporal signal, configure the tone setting on the base for steady.
To install the base:
1. The unit default is for high dBA output. To set the output to low
dBA, cut the circuit board trace as marked on the back of the PC
board. See Figure 3.
2. The unit default is for temporal pattern output. To set the output to
steady tone, cut the circuit board trace as marked on the back of
the PC board. See Figure 3.
3. Select and install a compatible electrical box, and bring the field
wiring into the box.
4. Install the trim ring and secure using screws. The trim ring is
included with the SB4U base. See Figure 2.
5. Make all wiring connections as shown in Figure 3.
6. Attach the base plate to the electrical box using the screws
provided with the electrical box.
7. Attach the trim ring to the base plate. Align the marks on the trim
ring and base plate, press the trim ring onto the base plate, and
then rotate the trim ring until it locks into place.
8. Attach the desired detector to the base. Align the arrows on the
detector and trim ring, press the detector into the base, and then
rotate the detector until it locks into place.
9. Apply power and activate the unit to verify that it is operating
properly.

Wiring
Wire in accordance with NFPA 72 and CAN/ULC-S524. Be sure to
observe the polarity of the terminals on the terminal block as shown in
the diagram.
Break the wire run at each terminal. Do not loop signaling circuit field
wires around terminals.
Refer to the applicable technical reference manual for application
diagrams.
Note: Shielded wire is required only in environments with very high
electrical noise. When you use shielded cable, follow these
recommendations:
• Shield connection to and from the base must be continuous and
must be insulated from ground. Insulate the shield using tape.
• For Class B wiring, there is no shield connection to ground at the
last device.
