Section 9-12 - RAM-1 (Redundant Amplifier Module)
Wheelock, Inc. Part Number: 108956
The Redundant Amplifier Module (RAM-1) allows the SAFEPATH
®
Panel to be configured to
meet the need for redundant amplification specifications. The RAM-1 provides 1 for 1 amplifier
redundancy. One RAM-1 is used with two amplifier modules of equal power rating (a primary and
a backup) to create one zone audio output. It mounts to the power supply cover in the panel in
lieu of a SPL.
The RAM-1 draws no power during stand-by and 50 mA during alarm. During alarm, only one
amplifier is energized. The second draws its standby current.
Additional Information is available on the RAM-1 Installation Instructions P83776.
