and the bus termination (TERM) condition. These settings are
described in the following sections.
•
TERM switch: To terminate the bus, set DIP switch 5 to
On, if needed. There must be no more than two TERM
switches or links set to On for any bus. Refer to the control
panel installation guide for details about the use of TERM
switches or links.
•
Keypad address: Set the keypad address using switches
1 to 4. See Figure 2.
Connections
See Figure 3.
•
+12 V, 0 V: The keypad can be powered using the bus "+"
and "−" power from the control panel (PS2 class PSU), if
the distance between the keypad and the control panel
does not exceed 100 m (328 ft.) Otherwise the keypad can
be powered by AUX PWR from a DGP, or by an auxiliary
power supply (PS2 class is required, 8.5 to 13.8 VDC,
recommended 12 VDC).
•
D+/D−: D+ is the data positive connection and D− is the
data negative connection of the data bus.
The keypad is connected to the ATS panel via the RS485
data bus, up to 1.5 km from the control panel. It is
recommended to use two-pair twisted, shielded data cable
(WCAT 52/54). D+/D- should be connected by one twisted
wire pair. The shield of any bus cable must be connected
to system ground at one end only. The ATS1136 keypad
does not provide an earth connection for this purpose. If
the bus is daisy-chained to the keypad, ensure that the
shield of the cable is jointed to provide continuity of data
cable shield. Isolate the wires and the shield of the cable
correctly to prevent any short circuit on the keypad.
•
IN: A request to exit button (normally open, momentary
push-button switch) can be connected across "IN" and
"0V" terminals. When pressed, this button controls the
request to exit function.
•
OUT: Open collector output. For maximum allowed
current, see "Specifications" on page 5. Refer to the
control panel programming manual for details.
