Section One: Introduction This troubleshooting guide addresses typical AM2020/AFP1010 hardware and software issues drawn from the Notifier Technical Services Department through customer input and experiences. This guide is not all encompassing; situations may occur that cannot be accurately accounted for when troubleshooting an AM2020/AFP1010 installation, and in that case, contact your Notifier Service Representative for assistance at 1-800-454-9779. -

Section Two: AM2020/AFP1010 Hardware Ground Fault. A Ground Fault is an unintentional connection of one or more system conductors (wires, equipment electronics, etc.) to some object which is electrically tied to (Also referred to as Earth Fault) earth ground. This connection may be direct contact, capacitive coupling, inductive coupling, or any combination of these things. -
Page 6: The Affects Of Multiple Impedances To Earth Ground
In a similar manner, a ground fault will be detected when a voltage carrying conductor (such as: +5 or +24 VDC) is faulted to earth ground. A representation of a positive ground fault is shown below. Note: The square wave is detected at an improper amplitude so a ground fault is indicated. -
Page 7: The Affects Of Capacitance On Ground Fault
For the sake of this example, let's assume that each of these impedances to earth is approximately 200,000 ohms. Since all these impedances have found a path to earth ground at Points "b","c","d","e", and "f" which are electrically effectively the same point as Point "a", all these impedances can be considered to be in parallel. - Page 8 The capacitive reactance formula can also be used to find the maximum allowable capacitance before an induced ground fault will result. solving the formula for C (Capacitance) yields; substituting the ground fault circuits frequency and threshold; Figure 2-6: Calculating the maximum allowable capacitance before a ground fault will be induced The result is approximately 12.73 microfarads.

2) Disconnect the EIA-232 loop from the Serial Interface Board. Wait for one minute. If the ground fault clears, reconnect this loop to the SIB but discon- nect the wiring from the external equipment (CRTs, printers, etc.) that are connected to this loop. If the ground fault clears, the problem lies with the external equipment. -

above 80% of the alarm threshold, and remains there for 26 consecutive hours (60 seconds for pre-alarm). If at anytime the level drops below 80%, the 26 hour (60 seconds for pre-alarm) timer is reset. Note: Addressable thermal detectors cannot cause a "Maintenance Required" or "Pre- Alarm Alert"... - Page 11 Figure 2-8: Detection Chamber Sensitivity and the Alarm Threshold without Drift Compensation. Figure 2-9: Detection Chamber Sensitivity and the Alarm Thresh old with Drift Compensation Drift Compensation is performed on every detector when the system is pow- ered up and every 120 hours (based on at least four samples). In addition, a Drift Compensation is performed on a specific detector whenever a non- communications Invalid Reply clears.

Page 14: Constant Invalid Reply
Constant Invalid Reply. The control panel is trying to poll a device (addressable detector, module, pull station) at a specific address and is either not receiving any response at all or it is not receiving a valid response. If two devices are set to the same address, an invalid reply may not occur immediately. -

If Relay Mapping is enabled (XPP switch 2=ON), it will consume two address (place a two in the blank). Depending on how each card is configured, the expander cards of the Transponder (XPC, XPM, or XPR) can take up to 8 addresses. If the card is an XPC-8 that is using all eight circuits (Style Y) and is also configured for Canadian Dual Stage operation, it will consume sixteen addresses. -

Page 19: What Is The Difference Between A Forward-Activated And A Reverse-Activated Zone
What is the Difference The main difference between a forward-activated zone and a reverse-activated Between a Forward- zone is as follows: Activated Zone and a Reverse-Activated Zone? A forward-activated zone has a Control-By-Event list of devices or higher numbered zones that it will activate when it (the zone) goes into alarm. It enters the alarm condition when an initiating device or lower numbered forward- activated zone (FZON) that is mapped to it goes into alarm. -

The executive routine keeps track of these tasks and sequentially Routine Re-entered. sends them to the microprocessor. The "micro" is given a certain amount of time to accomplish each task. - Page 32 Each time the system is powered up or reset, the CPU performs a test of both T05 CPU External RAM the static RAM and nonvolatile RAM chips. This involves alternately writing Test Error. zeros and ones to each memory location on these chips and reading the information back.
