AEM-48A: The Annunciator Expander Module-48A expands the ACM-48A by 48 system points. The AEM-48A is identical in frontal appearance to the ACM-48A. One expander module can be supported by an ACM-48A, providing a maximum of 96 points (subject to the capability of the FACP). 8.375″ (21.27 cm) high; 4.375″ (11.11 cm) wide. NOTE: The AEM-48A cannot be used to expand the ACM-24AT
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.
