AOM-2SF Supervised Control Module
INSTALLATION AND MAINTENANCE INSTRUCTIONS
BEFORE INSTALLING
This information is included as a quick reference installation guide. Refer to
the control panel installation manual for detailed system information. If the
modules will be installed in an existing operational system, inform the opera-
tor and local authority that the system will be temporarily out of service. Dis-
connect power to the control panel before installing the modules.
NOTICE: This manual should be left with the owner/user of this equipment.
GENERAL DESCRIPTION
AOM-2SF Supervised Control Modules are intended for use in intelligent, two-
wire systems, where the individual address of each module is selected us-
ing the built-in rotary switches. This module is used to switch an external
power supply, which can be a DC power supply or an audio amplifier (up
to 80 VRMS), to notification appliances. It also supervises the wiring to the
connected loads and reports their status to the panel as NORMAL, OPEN, or
SHORT CIRCUIT. The AOM-2SF has two pairs of output termination points
available for fault-tolerant wiring and a panel-controlled LED indicator.
COMPATIBILITY REQUIREMENTS
To ensure proper operation, this module shall be connected to a compatible
Gamewell-FCI system control panels only (list available from Gamewell-FCI).
MOUNTING
The AOM-2SF mounts directly to 4-inch square electrical boxes (see Figure
2A). The box must have a minimum depth of 2
1
/
8
inches. Surface mounted
electrical boxes (SMB500) are available. The module can also mount to the
DNR(W) housing.

WIRING
NOTE: All wiring must conform to applicable local codes, ordinances, and reg-
ulations. When using control modules in nonpower limited applications, the
CB500 Module Barrier must be used to meet UL requirements for the separa-
tion of power-limited and nonpower-limited terminals and wiring. The barrier
must be inserted into a 4˝ × 4˝ × 2
1
/
8
˝ junction box, and the control module
must be placed into the barrier and attached to the junction box (Figure 2A).
The power-limited wiring must be placed into the isolated quadrant of the
module barrier (Figure 2B).
1. Install module wiring in accordance with the job drawings and appropri-
ate wiring diagrams.
2. Set the address on the module per job drawings.
3. Secure module to electrical box (supplied by installer), see Figure 2A.
Wire should be stripped to the appropriate length (recommended strip length
is
1
/
4
“ to
3
/
8
”). Exposed conductor should be secured under the clamping plate
and should not protrude beyond the terminal block area. Caution: Do not loop
wire under terminals. Break wire run to provide supervision of connections.
IMPORTANT: When using the AOM-2SF for audio applications, remove Jumper
(J1) and discard. The Jumper is located on the back as shown in Figure 1B. J1
must be removed whenever power supply monitoring feature is not required.
NOTE: All references to power limited represent “Power Limited (Class 2)”.
All references to Class A also include Class X.
