Appendix D: AM2020/AFP1010 Systems (UL 8th)
D.1 Capabilities
When installed with an AM2020/AFP1010, annunciators can be programmed to annunciate the status of addressable devices, software
zones, and several system control functions:
•
Devices
– Photo, Ion, and Heat Intelligent Detectors
– Monitor and Control Modules
– Addressable Manual Pull Stations
Refer to the appropriate FACP manuals for more information.
•
Software Zones 1-240
•
System Controls
– Acknowledge/Step (the ACK/STEP key)
– Signal Silence
– System Reset
– Lamp Test
•
XP Series Transponder System
– Power and Audio Supply Supervision
– XP Series Form-C Alarm and Trouble Relays
– Control, Monitor, and Relay Module Circuits
D.2 Connecting the EIA-485 Circuit
The AM2020/AFP1010 must include an intelligent Serial Interface Board
(SIB-2048A/SIB-NET). Up to two EIA-485 circuit loops may be connected to the SIB as
shown in the accompanying illustration.
See Section 4.3, “EIA-485 Wiring Specifications” for details and notes about EIA-485
requirements.
Software Requirements: ACM-16AT, ACM-32A
The AFP1010 is fully compatible with ACS annunciators. The AM2020 must be operat-
ing with software with the following part numbers (or greater) shown in Table D.1.
D.3 Providing Power to Annunciators
AM2020/AFP-1010 panels use Main Power Supply MPS-24A. The annunciator’s power supply is con-
nected to +24V non-resettable power; use the middle two pins on TB3 of the MPS-24A as shown in the
accompanying illustration. Do not cut jumper JP5! No more than 3A can be drawn from these power-lim-
ited terminals in standby or alarm.
The power run to the annunciator does not require a Power Supervision Relay. Loss of power is inherently
supervised through a Communications loss. This 24 VDC output is supervised, power-limited, filtered, and
non-resettable.
