The Annunciator Expander Module-24AT expands the ACM-24AT by 24 system points. The AEM-24AT is identical in size and in frontal appearance to the ACM-24AT. Up to three of these expander modules can be supported by an ACM-24AT, for a maximum of 96 system points. NOTE: The AEM-24AT cannot be used to expand the ACM-48A
SPECIFICATIONS
Electrical Specifications
Supply Power: 24Vdc nominal (17Vdc to 28Vdc)
Current draw (On-line Flashing, all other LEDs off):
– ACM-24AT/ACM-48A: 0.016 A.
– ACM-24AT/AEM-24AT: 0.002 A.
Current draw (Alarm, all LEDs are assumed to be on):
– ACM-24AT/ACM-48A: 0.070 A.
– ACM-24AT/AEM-24AT: 0.056 A.
Note: This assumes that all LEDs are lit simultaneously. When the alarm system specification permits, calculations can be based on a 10% alarm loading capacity but do not enter less than one.
