The AMPS-24/E is an intelligent power supply and battery charger with one 5VDC and three 24
VDC outputs. It can connect directly to a CPU2-3030*, NCA-2 or DS-DB via a harness cable with
EIA-485 connections. For other systems it can operate in FlashScan or CLIP (Classic Loop
Interface Protocol) mode and reside on the SLC. The AMPS-24 includes a battery charger capable
of charging up to 200 AH batteries.
*Note that the CPU2-3030 must connect to the SLC as well to get correct trouble status reporting. Refer to "SLC Addressing" on
page 30.
The AMPS-24/E may be installed remotely from an ONYX Series panel, connected as an SLC
device in either FlashScan or CLIP mode to provide system supervision. In this configuration, it
can simultaneously charge batteries and power remote devices. (See block diagram Figure 2.12 on
page 22.)
