2. Check voltage at AE-2000 power terminal strip.
Buzz on speaker
1. Check for 24 volt AC power shorted to wiring conduit.
2. Check for telephone line shorted to ground.
3. Verify that telephone wires are twisted pair.
4. Verify that the AE-2000 is connected to earth ground.
5. Check 16 VAC voltage at AE-2000 transformer terminals.
Buzz on telephone line
1. Disconnect 16 VAC wires from terminal strip, if buzz goes away,
one side of the transformer wires is grounded.
2. Check all connections for any shorts to ground.
System will not answer an incoming call
1. Automatic telephone answer disabled.
2. AE-2000 telephone line trouble.
Entry code will not activate relay

2. Entry code not set up for proper relay.
3. Keypad is in lockout.
Remote PBUS device does not work

1. Resident’s telephone number programmed incorrectly.
2. Check AE-2000 telephone line.
3. Call resident from another line or cell phone to determine if the
resident’s telephone is working.
Transmitter does not activate relay
1. Transmitter button setting programmed to “none” (would effect all
transmitters).
2. Transmitter not enrolled.
3. Specifi c transmitter is deactivated in the system.
Poor transmitter radio range
1. Check antenna installation and condition if transmitters were
previously working well.
2. Check the RADIO indicator on the AE-2000 circuit board. If it is
fl ickering without activating any transmitters there is interference
blocking the receiver. Try adjusting the RECEIVER RANGE knob
to reduce the receiver’s sensitivity to the interference.
3. Connect an audio amplifi er or telephone buttset to the RECEIVER
TEST POINTS (the wire jumpers next to the RECEIVER RANGE
knob). Listen to the sounds of the signals being received. If you
hear the interference, remove power from possible interfering
devices to determine the source of the interference. The antenna
or the interfering device may need to be relocated.
4. Use Model FT-1 to check for interference.
