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.
When working on the AM2020/AFP1010, the typical power down sequence
should consist of the following steps:
1) Remove any SIB field wiring.
2) Disconnect the battery connection from the main power supply, MPS-24A
TB2 terminals 1(+) and 2(-).
3) Shut off all sources of AC power from the panel.
4) Allow the panel to discharge for approximately one minute before connect-
ing or disconnecting any ribbon cables or harnesses or removing or adding
any circuit boards.
When reapplying power, always reconnect AC power before reconnecting the
batteries. Failure to follow this procedure may result in damage to the panel or
loss of programming. The following steps must be completed to reapply power to
the AM2020/AFP1010:
1) Connect all internal cables and components.
2) Apply AC power.
3) Connect batteries.
4) Reconnect any SIB field wiring.
When handling a printed circuit board or removing or installing EPROMs, proper
static precautions must be observed. This includes wearing a grounding strap
and clipping it to an appropriate ground point so that any potential in your body
may be safely discharged to earth.
