ATS1840 Fuse Board Installation Sheet
EN DE FR
EN: Installation Sheet
Description
ATS1840 is an 8-way fuse board to provide for separate fused
power supply outputs. Fuse fail is indicated by a dedicated
output that can be connected directly to any zone on the ATS
control panel (or ATS1201 DGP).

Description
Function
(1)
Mains fail
detection
Connected to zone input on control panel or
DGP.
When no fuse fail present output equals
standard end-of-line resistor value (4.7 k
Ω).
In case of fuse fail present output equals
double end-of-line resistor value (9.4 k
Ω).

Connected to (auxilliary) power output from
control panel or DGP.

Power supply
outputs
8 power supply outputs, separately fused.
Mounting
The ATS1840 can be mounted into any ATS control panel or
ATS1201 DGP using the spacers provided.
To mount ATS1840 into the Advisor Master control panel
or ATS1201 DGP:
1. Place the clips in the square holes (4) (use metal pillars
when available).
2. Mount the ATS1840 using screws.
Connecting the ATS1840
1. Connect (auxiliary) power supply from the control panel or
DGP to "+12 V" and "0 V" (J3).
2. Connect "OUT" and "C" (J3) to a zone input on the control
panel/DGP. "C" needs to be connected to "C" of the zone
input.
3. Connect required fused power supply to power supply
outputs 1 to 8 (J1/J2).
