·        General Notes

Make sure the RF receiver is properly addressed (00)

• If using a 5881 RF receiver:

Ø       Switches should be set with switch all OFF (address 00).

Ø       Toggle the dip-switches (off, then back on) this will ensure that they are seated properly.

Ø       There is no cover tamper on the 4281 or 5881 receiver.

• If using a 6128RF or 6150RF receiver in the system mode:

Ø       Set the address to 00 by pressing 1/3 together after power up, then press 2 0 0 * *

Make sure the RF receiver is properly wired

• Verify wiring to the RF receiver from the control panel. The harness should be wired:

Panel Terminal                        Receiver wire

4                     Black wire

5                     Red wire

6                     Green wire

7                     Yellow wire

• Check voltages on the data wires. With reference to black, you should read:

Red = 13.5VDC

Yellow = 11-13 VDC (fluctuating)

Green = a few millivolts with some fluctuation

The 6150RF keypad has a tamper switch on the PCB.

• If using a /6150RF in the system mode, the red tamper switch on the back can cause a CHECK 100.
• The 6150RF must be securely mounted on its base.
• Try holding the tamper in for 2 minutes, then see if the keypad clears.

Make sure there is only one RF receiver in the system.

• This includes 5881 and 6128RF/6150RF in system mode.
• If using a 6128RF/6150RF AND a 5881 receiver, the RF keypad must be set to LOCAL.

Ø       Set to local by pressing 1/3 together after power up, then press 6 0 * *

Ø       The RF keypad may be used for keyfobs programmed locally into it.

Do you also have a CHECK 90?

Ø       If something “jams” the RF receiver with a continuous signal it can interfere with the receivers ability to receive signals from the transmitters. The control panel will report a Check 90 condition if a jamming condition lasts for more than 20 seconds.

Ø       A check 100 may accompany a Check 90

Ø       Check90 is usually seen by the red LED on the 5881 flickering or glowing continuously.

Ø       The newest 5881 receivers (PCB marked 5882) have the ability to detect an RF jamming condition.

Isolate the wiring

• To verify the integrity of the wire harness, try to operate a keypad from the same harness; or replace the harness.
• Move the receiver to the control panel and retest.
• It is important that the data wires for the receiver not t-tap to go to other devices. The receiver should have its’ own home-run wire to the control panel.
• Remove all other ECP devices and wires except a keypad and the RF receiver to isolate the system.

If you are NOT using wireless

The system is has a wireless zone enabled in programming.

This zone must be deleted to disable supervision of the receiver that you don’t have.

General Notes

Also, don’t overlook the basics: check the panel AC, battery, etc… If anything at all goes wrong with the panel the Check 100 may be the symptom. This is because the expansion modules are supervised and other devices are not.

For example, a problem with a keypad could cause a problem on the ECP data bus. Because the keypad is not supervised, no trouble condition is associated with this. However, the ECP problem could cause a communication problem to the expanders and therefore result in a Check 100.
