Answer:
The slave pedestal acts as a secondary antenna that pairs with an EAS-AM-88 master unit rather than operating independently. It utilizes the master pedestal's central controller and power feed to create a balanced, wide multi-pedestal detection zone.
In an EAS-AM-88 installation, pedestals are configured in a Master/Slave architecture:
- Master Unit: Contains the primary Digital Signal Processing (DSP) motherboard, power supply interface, and central synchronization controls.
- Slave Unit: Houses the 58 kHz antenna loop, visual LED alarm bars, and acoustic alert hardware, drawing power and synchronization signals directly from the connected master controller.
Adding the slave pedestal allows retail facilities to expand corridor coverage across standard exit widths up to 2.4 meters for hard tags without purchasing two standalone master systems, significantly reducing deployment cost per aisle.
