ATS1821 Eight-Way Digital Output Card
Installation Sheet
EN DE
EN: Installation Sheet
Description
The ATS1821 is an interface between ATS control panels and
stand-alone diallers/transmitters using open collector outputs.
The ATS1821 uses outputs 4 to 11 (outputs 1 to 3 on control
panels are hard-wired to sirens/relays).
Note:
For the outputs to become operational, set the number
of output controllers in the ATS control panel (menu System
Options) to two (2).
Mounting the unit
The ATS1821 must be mounted in the same enclosure as the
control panel and are connected with the cable supplied.
Wiring
To connect the ATS1821 to the ATS control panel, plug the 10-
wire flat cable in J1 of the control panel and CON1 of the
ATS1821.
Outputs
The ATS1821 provides for eight 50 mA open collector outputs
with internal pull-up resistors of 4.7 k
Ω. Cards can be fitted to
the ATS control panels or DGP but can not be daisy-chained to
provide multiple outputs
Output wiring
All ATS1821 outputs have a 4.7 k
Ω resistor pulled up to the
supply voltage. The outputs have been designed such that
they can be connected directly to stand-alone
diallers/transmitters like the TD84/88, Redcare unit or
TDI2801. Connect the 0 V to the 0 V of the dialler/transmitter.
Note:
If the dialler/transmitter is not fitted in the same
enclosure, use relay cards like the ATS1810 or ATS1811.
