KMC Controls SAE-1152(OLD Style Board w/ LEDs) - Manual (Page 2)

NOTE: The Detector has a half-wave type power supply. The power supply common is
the same as the output signal common. Therefore, several units may be connected to
one power supply and the output signals all share the same signal common.
CAUTION: Use caution when grounding the secondary of an AC transformer or when
wiring multiple devices to ensure that the circuit ground point is the same on all
devices and the controller.
See Application Note AN0604D
The analog output signals are available on the +OUT and -OUT terminals (consult wiring
diagrams).
1. Jumper to select an output
◆ 4 to 20 mA (active or passive output)
√
Active Mode does not require a loop power supply.
√
Passive Mode requires a loop power supply. Output signal will operate the
same as a loop powered device.
◆ Use a second jumper to select voltage output range 0 to 5, or 0 to 10 VDC.
CAUTION: DO NOT connect to a powered input or device, damage will result.

2. Check the controller’s Analog Input to
determine the proper connection BEFORE
applying power.
NOTE: The analog output signal is
typically connected directly to the
Building Automation System (B.A.S.) and
used as a control parameter or for
logging purposes.
Two optional signals are the relay outputs available
on the NO1, NO2, COM1, COM2, NC1 and NC2
terminals. The Relay Com terminals are NOT
connected to signal or power supply, COMMON
terminal or to each other.
The relay outputs are completely isolated and
include both Normally Open (NO) and Normally
Closed (NC) signals. These signals can be used to
directly control alarms, ventilation fans or may be
connected to a digital input of the B.A.S. for Status
monitoring.
