AMC-1225 SENSOR MODULES

NOTE:

Turn off the power supply before removing or replacing the sensor.

Connection should be made using 3 conductor shielded cable ( shield must be grounded at the

monitor ). Run cable through steel conduit for best signal transmission and maximum noise

rejection. A maximum length of 150 feet of 18 AWG stranded wire is allowed between each unit

as well as between the monitor and first units. For other distances or cable sizes consult with

The Armstrong Monitoring Corporation.

4.2.1 MULTI-UNIT INTERCONNECTION

Each sensor is designed to interconnect to other units in series and/or parallel combinations.

Figure 4-4

Various typical configurations are shown in

, illustrating the versatility of this type of

system. Because each sensor is pre-calibrated, additional units can be added to a system

without altering the monitor settings. When multiple units are interconnected, either some or all

jumpers need to be removed. See Figure 4-3

For any unused terminals a jumper has to be inserted. See Figure 4-3. Failure to do so may

cause the system to malfunction.
