4. Apparatus connected to the optional alarm contacts shall be FM Approved as
Associated Nonincendive Field Wiring Apparatus and shall comply with the
following requirements:
Voc equal to or less than Vmax
La equal to or greater than Li
Ca equal to or greater than Ci
5. Terminals S1 to S7 shall be connected to simple apparatus or volt free contacts of
FM Approved Nonincendive Field Wiring Apparatus or FM Approved Associated
Nonincendive Field Wiring Apparatus installed using Division 2 wiring methods.
6. To maintain IP65 protection between the BA488CF and the mounti ng panel:
Four panel mounting clips should be used
Minimum panel thickness should be 2mm (0.08inches) Steel
