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.
