The lives of people depend upon your safe installation of the AIM-3. Please read, understand and follow the specific installation
instructions set forth below to avoid damage to the AIM-3 and equipment connected to it. Installation should be conducted only
by qualified persons in accordance with procedures in this manual.
WARNING: SHUT OFF ALL POWER BEFORE STARTING THE INSTALLATION. ELECTRICAL SHOCK CAN
CAUSE DEATH OR SERIOUS INJURY.
CAUTION: The AIM-3 printed circuit boards are sensitive to static electricity and have delicate components mounted on them.
Before handling either a board or any component on a board, discharge any static electricity from your body by touching a grounded
object such as a metal screw which is connected to earth ground. Handle the board by its edges, and be careful not to twist or flex it.
The AIM-3 is to be installed in a static free area and the user is to properly attach grounded wrist straps before touching any static
sensitive areas. After handling AIM-3 printed circuit boards, the Series AIM-3 should be tested in accordance with the “System
Checkout” section to verify that the printed circuit boards are undamaged and functioning properly.
CAUTION: The Authority Having Jurisdiction (AHJ) should be consulted by the installer prior to installation.
Installation Guidelines:
1. Prepare a drawing of the complete system wiring. (Keep a copy of the system wiring drawing and the AIM-3 Manual with the
SAFEPATH panel for reference during the life of the system.) This manual shall be made available to all qualified personnel
who operate, test, maintain, or service SAFEPATH products.
2. Carefully unpack the AIM-3 and make sure each item described on the packing slip is present and undamaged.
3. Mount the AIM-3 in the desired location as described in the "Mounting" section.
4. Mount any additional wiring boxes or junction boxes needed to interconnect field wiring.
5. Connect conduit fittings or bushings as needed using knockouts provided on the top and bottom of the AIM-3 units (see Figure
2).
6. Install field wiring in conduit when necessary, following the National Electrical Code and local codes for the type of system
being installed. Make all necessary connections at any additional wiring or junction boxes.
CAUTION: Provide proper strain relief for all wiring not in conduit.
7. Connect the AIM-3 to earth ground, following the National Electrical Code and local codes for the type of system being
installed, as described in the “Grounding” section.
8. Check the integrity of all field wiring following the directions in the "Field Wiring Checkout'' section. Confirm that the
specified cable is installed and that there is continuity between required points (no open circuits), with no unwanted connections
(shorts) to other conductors, chassis, or earth ground.
9. Connect the wiring to the appropriate terminals of the AIM-3 modules following the directions in the "Field Wiring" section and
the system wiring drawing you created in Step 1.
10. Set the switches for the proper configuration as described in the “Configuration” section.

Wiring Guidelines:
Although the AIM-3 incorporates signal verification and noise filtering circuitry on its input, induced voltages or “noise” on the input
wiring can cause improper operation. Therefore, use shielded twisted pair wire for all file input wiring. The audio output lines (and
the auxiliary music input lines) should also be wired with shielded twisted pairs to minimize noise pick-up. For all other connections,
twisted pairs are recommended so as to reject common mode noise, shielding is optional.
The shield of each cable should be connected only at one end. Each shield of each cable that connects to the AIM-3 is to connect to
the grounding points provided near the right edge of the chassis (see Figure 2).
WARNING: ALL AIM-3 WIRING SHOULD BE ROUTED AWAY FROM ANY HIGH VOLTAGE OR HIGH
CURRENT LINES (SUCH AS AC OR DC POWER LINE, AUDIO POWER LINES, AND MOTOR OR RELAY
ACTUATION LINES) AND SHOULD BE INSTALLED IN SEPARATE CONDUIT FROM HIGH VOLTAGE OR HIGH
CURRENT LINES. FAILURE TO DO SO MAY CAUSE ELECTRICAL SHOCK WHICH CAN RESULT IN PROPERTY
DAMAGE AND SERIOUS INJURY OR DEATH TO YOU AND/OR OTHERS.
The National Electrical Code defines two types of circuits for protective signaling systems: power limited circuits and non-power
limited circuits. All AIM-3 circuits have been designed as power limited circuits. Therefore, in order to maintain power limited
ratings, circuits connected to the power supply, auxiliary source input, and relay contact terminals of the AIM-3 must be powered
limited.
CAUTION: The National Electric Code limits the maximum number of conductors that can be installed in conduit and wiring
boxes depending on the size of the conduit, the volume of the boxes, and the gauge of the wire used. Make sure that wiring used for
AIM-3 installation complies with the latest NEC requirements for power limited circuits.
Wiring Specifications:
Between each RM and AIM-3
Cable Size:
14 - 22 AWG Shielded. The shield must be connected only at the SAFEPATH Panel.
Maximum Length:
1000 Feet
Maximum Capacitance:
. 05uF/Total Run (50pF/foot for 1000 FT.)
Mounting:
The AIM-3 shall be mounted in a location within the environmental limits specified in the latest UL Standard for indoor control
panels. The AIM-3 shall not be located in a hazardous location. Refer to the "Technical Specifications'' section.
CAUTION: In order to comply with the latest NFPA and UL requirements for interconnection of fire alarm control equipment,
the AIM-3 unit must be located in the same room as, and within 20 feet of the SAFEPATH Panel it is connected to.
Refer to Figure 2 for AIM-3 mounting hole layout. Drill mounting holes for appropriate screws and anchors to ensure secure
mounting to the type of surface at the selected location. Keep out dust and dirt during installation. Dust and dirt can interfere with
the operation and reduce the life of the equipment.
Remove the outer cover and mount the Series AIM-3 at the selected location. Use care to avoid damage to the PC board during
installation. Do not apply excessive pressure to the PC board or its components, including field wiring terminals and connectors or
damage may occur.

Telephone Input Applications:
The AIM-3 can be connected to an unused CO Port, a page port, an analog station port ( with TPI-100 ) or to a zone control (MCZ144 ). When it is used for telephone paging, it should only be used for telephone paging only and not for background music. The
VOLUME adjust is used to set the telephone page volume. When using the AIM-3 with the single circuit SAFEPATH (SC-SAPE ),
verify the SC-SAPE controller software (U5) is Rev E or higher. When using the AIM-3 with other SAFEPATH panels, verify the
controller software (U3) is Rev D or higher. Failure to do so could result in improper operation.

Field Wiring Checkout:
Refer to NFPA for guidelines on testing signaling system wiring.
CAUTION: Do not connect input voltage to any equipment until the field wiring has been inspected, tested and approved.
1.
Verify that the field wiring is in full agreement with this manual and with the detailed wiring layout prepared for this installation.
Ensure that no unwanted voltages are present on circuit conductors and ground.
2.
Test all ungrounded connectors for electrical isolation from ground.
3.
Test all wires that are not intentionally connected for electrical isolation from each other.
4.
Measure and record the resistance of each circuit pair (this can be done by temporarily short circuiting one end of the circuit).
Configuration:
Configure the AIM-3 by using the three switches and potentiometer ( see Figure 8):
RM1 on enables the Remote Microphone attached to RMS-1 port.
RM2 on enables the Remote Microphone attached to RMS-2 port.
RM3 on enables the Remote Microphone attached to RMS-3 port.
PHONE on enables the telephone input attached to RMS-3 port.
RM/ PHONE RM enables Remote Microphone attached to RMS-3 port.
PHONE enables the telephone input attached to RMS-3 port.
TALK BATT provides talk battery for unused CO Port.
Volume potentiometer is used to adjust telephone page volume.
Operation:
The AIM-3 polls the Remote Microphone stations to determine supervision and alarm status. Any trouble condition will light the
amber LED. Follow the trouble shooting procedures if the LED is lit. The first Remote Microphone that is selected will have priority
over the other two. See the Remote Microphone instructions for Remote Microphone operation.
To set the telephone page volume use the VOLUME potentiometer adjust and the PEAK level red LED. Occasional flickering of the
LED indicates momentary peak levels, and is a normal operating condition. Steady illumination of the LED is an indication that an
overdrive (clipping) condition may exist. If distortion is audible, then lower the page volume.
