External Cabinets
The CAB-A3F and the CAB-B3F are UL listed cabinets suitable for use in
graphic annunciator applications. For size and dimensions, refer to the CAB-
3F Series Installation Document.
Select and remove the appropriate knockout(s) on the cabinet.
Securely mount the cabinet.
Ground the cabinet to a solid electrical ground per NEC Article 250.
Pull all wiring into the cabinet. (Refer to the appropriate FACP manual for UL
Power-limited Wiring Requirements.)
Note: Other cabinets such as those provided by custom graphic annunciator
manufacturers may be used provided they meet UL requirements as UL listed secured
enclosures.
CHS-4L Chassis
The CHS-4L chassis will support one LDM-32F module and up to three LDM-
E32F expander modules. The chassis is mounted inside the CAB-A3F or the
CAB-B3F cabinet.
Mount the CHS-4L Chassis to a cabinet and secure with the hardware provided.
The Grounding Cable must be connected to the chassis mounting stud for
connection to the annunciator's earth ground terminal for proper operation as
well as to aid in transient protection. For each LDM module to be installed on
the chassis, connect two female-to-female standoffs (provided) to the upper
mounting studs on the chassis.
