SIGA-AB4GT CO Compatible Sounder Base
Installation Sheet
AB4G-SB: When using the AB4G-SB surface mount 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 a conduit connector and nut (not
supplied). See Figure 1.

Description
The Signature Series model SIGA-AB4GT CO Compatible
Sounder Base is a sounder base specifically designed for use
with CO sensors. It is not compatible with a coded system.
The base uses the same address and programming label as
the detector it supports. It requires a SIGA-TCDR Temporal
Pattern Generator to add the audible output function to any
Signature Series detector.
Refer to Figure 4 when following the installation steps below.
To install the sounder base:
1.
Select and install a compatible electrical box, and bring
the field wiring into the box.
2.
The default volume setting for the base is high dBA. To
configure it for low dBA, cut the circuit board trace on the
back of the circuit board. See item 4 of Figure 2, and
Table 4.
3.
Connect the field wiring to the terminals on the back of the
base plate. For the unit to function properly, observe
polarity. See Figure 2.
4.
Attach the base plate to the electrical box. See Figure 4.
5.
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.
Installation
ATTENTION: Read this installation sheet in its entirety before
beginning. Follow the installation instructions and keep them
for future reference.
Install in accordance with applicable requirements of the latest
editions of the NFPA codes and standards, and the authority
having jurisdiction. In Canada, install according to
CAN/ULC-S524 Standard for the Installation of Fire Alarm
Systems, CSA C22.1 Canadian Electrical Code, and the local
authority having jurisdiction.
Caution: To avoid accidental damage to the panel, disconnect
all power before wiring the unit.
Notes
•
Do not loop the signaling circuit field wires around the
terminals.
•
Do not use AB4G and AB4GT on the same power riser
circuit.
Base Location: Refer to the detector installation instructions.
Sleeping Rooms: In sleeping areas, use the high dBA output.
