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.
