HONEYWELL BKM-0001 Battery and Key switch Module

Description

The Battery and Key Switch Module (BKM-0001) is installed in the Controller chassis, with references to “CPCHAS-0001” (pages 87 and 116) or “CPCHAS-0002”.

• Each Controller chassis, even redundant ones, contains only one BKM-0001.
• Components included in the BKM-0001:
  • Two batteries (one for each Control Processor).
  • Force Enable key switch.
  • Reset key switch.
  • Three 24 Vdc general-purpose inputs (IN1, IN2, IN3) located on the Controller backplane.
