AB4G Audible Detector Base Installation Sheet
Description
This installation sheet applies to AB4G Audible Detector Base
units with model numbers GSA-AB4G and SIGA-AB4G.
The AB4G Audible Detector Base adds an audible output
function to any Signature Series detector. The output of this
detector base is field-configurable for output tone (steady or
temporal) and output volume (low or high dBA).
Depending on the system supporting the Signature loop, the
base can:
• Follow the state of the device it supports
• Be configured (in the SDU) for other operating modes
• Be controlled by program rules
The base uses the same address and programming label as
the detector it supports.
Installation
Install this device in accordance with applicable national and
local codes, ordinances, and regulations.
Cautions
• To avoid accidental damage to the panel, disconnect all
power before wiring the unit.
• Do not loop the signaling circuit field wires around the
terminals.
Note: Always connect the base to a continuous voltage,
whether the output tone on the audible detector base is set to
steady or temporal.
Sleeping rooms: In sleeping areas, use the high dBA output
and temporal tone settings.
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.
Refer to Figure 2 when following the installation steps given
below.
To install the audible detector 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 then
bring the field wiring into the box.
4. Connect the field wiring to the terminals on the back of the
base plate. For the unit to function properly, observe
polarity. See Figure 3.
5. Attach the base plate to the electrical box.
6. Align the trim ring so that the four tabs on the ring mate
with the four slots in the base plate, and then press the
trim ring onto the base plate until the tabs lock.
7. Attach the desired Signature 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.
8. Apply power and activate the unit to verify that it is
operating properly.

Applications
This section describes applications typically found in the North
American marketplace that apply to the AB4G and Signature
audible bases. For additional examples, see the applicable
control panel application manual.
Local alarm signaling application
Figure 4 shows the components and wiring required for a local
alarm signaling application.
All other audible detector bases on the same riser remain silent
until their detectors are activated. The audible detector base
remains audible until the smoke clears and the control panel is
reset.
Zone alarm signaling application
Figure 5 shows the components and wiring required for a zone
alarm signaling application.
In this application, use a CRR module to activate all the
audible detector bases in the same notification zone when any
one of their detectors activates (initiates an alarm event). The
audible detector base remains audible until:
• Smoke is cleared from the active detectors and the control
panel is reset.
• The control panel’s Auto Signal Silence timer expires.
• It is silenced by the CRR that is programmed as a
silencing relay. (This function of the CRR is panel
dependent.)
For more information about the Auto Signal Silence timer
function, and if the CRR can be programmed to silence the
panel, see the applicalbe control panel manual.
Synchronized alarm signaling application
Figure 6 shows the components and wiring required for a
synchronized alarm signaling application.
In this application, use a CRR module to activate all audible
detector bases when any alarm signal-initiating device
activates. Use a G1M-RM to synchronize the sound. The
audible detector base remains audible until:
• Smoke is cleared from the active detectors and the control
panel is reset.
• The control panel’s Auto Signal Silence timer expires.
• It is silenced by the CRR that is programmed as a
silencing relay. (This function of the CRR is panel
dependent.)
For more information about the Auto Signal Silence timer
function, and if the CRR can be programmed to silence the
panel, see the applicalbe control panel manual.
