About the operation of the panel

Use of intelligent and addressable detectors and modules provide the operator with precise information on the
location of the alarm or trouble, as well as what type of device is reporting the activity.
The AM2020/AFP1010 control panel will only operate with Notifier intelligent addressable devices installed.
All operating power, as well as data communications to and from intelligent and addressable devices, is
transmitted on a two-wire LIB Signaling Line Circuit (SLC) that may be wired to meet the requirements of either
NFPA Style 4 (Class B) or Style 6 or 7 (Class A)operation. The AM2020 system can be configured with up to 10
LIB SLC Loops and the AFP1010 system with up to 4 Loops, each of which is capable of supporting up to 99
intelligent detectors and up to 99 addressable control or monitor modules.
Note: The term "loop" is used in a general way throughout this document and does not necessarily mean that the
circuit is a Class A configuration, unless a reference is made to Style 6, Style 7, Style D, or Style Z circuit
performance.
A fire alarm in the AM2020/AFP1010 is initiated by activation of any of the following devices:
• Intelligent smoke or heat detectors (SDX-551/751, SDX-551-TH, CPX-551/751, FDX-551, or
IPX-751, etc.).
• Addressable Manual Pull Stations (BGX).
• Conventional normally-open or normally-closed contact fire alarm initiating devices connected to
addressable MMX Monitor Modules (or equivalent XPM or XP5-M circuits) along a LIB SLC.
During an alarm condition, LEDs on as few as six and as many as 99 addressable initiating devices (smoke
detectors, heat detectors, MMX modules etc.) and/or output modules may be latched on. A latched-on LED on
an initiating device indicates that the device has caused an activation signal to be transmitted to the AM2020/
AFP1010. A latched on LED on an output module indicates that the module has been activated. An activation
signal on the AM2020/AFP1010 includes fire alarms, security alarms, supervisory conditions, or non-alarm inputs.
During loss of primary (AC) power, when the AM2020/AFP1010 is operating under secondary power, only LEDs
on intelligent detectors (including DHX-501/DHX-502 duct detectors) will be latched on during a fire alarm.
The AM2020/AFP1010 can be programmed to latch the LEDs on up to
99 addressable devices (MMX, CMX, etc.). This software feature can be
used only if ALL installed addressable devices are stamped with the code
R4 on the product marking label (purchased from Notifier after April 1,
1991.) Use of this feature under any other circumstances can cause the
LIB SLC Loops to shut down during a fire alarm condition. RA-400
Remote LEDs are not permitted for use with this feature (excluding those
wired to DHX-501/DHX-502 Duct Detectors). Use only the RA-400Z
Remote LED when extending the number of latched-on LEDs beyond six.
SDX-551 Photoelectric Detectors can also have an H code after their
model numbers.
Detectors have priority over modules. Detectors that come into alarm will assume LED-latch priority
Output devices (alarm notification appliances, output relays, etc.) are controlled by activation of CMX Control
Modules (or equivalent XPC or XPR circuits) connected along the LIB SLC. A control module may serve as a
Form-C output relay or as a Notification Appliance Circuit (NAC).
About this Chapter
This chapter covers the operation of the AM2020/AFP1010 Combination Fire/Security Protective Signaling
System and the control features available to the operator presented through the perspective of the Display
Interface Assembly (DIA-2020 or DIA-1010).
