HANGEOVER
C
ONTROL
Type Current sinking type (also referred to as ground closure type).
Purpose Controls output selection when the system changeover mode
is configured for GPI.
Input activation Selects secondary channel set
≤1.0 V (wrt interface system 0V)
≤6 k Ω (contact to interface system ground)
Input deactivation Selects primary channel set
≥ 2.0 V (wrt interface system 0V)
Maximum input voltage + 60 V

UTPUT
Type Relay contact -Latched
Purpose Indicates current output channel set
(Retains indication when system loses power).
Sense Open = Primary channel set selected
Closed = Secondary channel set selected

A
LARM
O
UTPUT
Type Opto-isolated floating type
Purpose Indicates if primary and secondary channel set signals are
different format or if there is PSU module failure.
Note: PSU module present but not powered or PSU module fan
failure constitutes PSU module failure.
Sense Floating = Alarm
Closed = OK
Max. load voltage +60 VDC
Max. load current 250 mA
Max. power dissipation 450 mW
