4) Locate the jumper in the center of the circuit board that says “Normal Operation” and “Factory
Defaults”. Move the jumper to the Factory Defaults position. Temporarily place the lid on the unit
and connect the power cable. Turn the power switch on for 2 minutes.
5) Turn the power switch OFF and disconnect the power cable. Remove the lid. Move the Jumper
back to the “Normal Operation” position. Reassemble the lid with the 8 screws. The unit is now
reset.
Configuring the Relay Output
The IMS-1000 includes a relay output that can be used to control a light, siren, or other low voltage
device. The output is a Form-C Normally Open/Normally Closed mechanical relay and is rated for
1A 30VAC or 1A 24VDC. A sample wiring diagram is shown below:

Output
12 V AC
The output connector is located on the front of the unit and is labeled “Output”. When connecting
wires to the output terminal block be sure to strip a 1 ⁄ 2 ” of wire insulation before inserting the
wire (see figure below):
1/2"
The output has three terminals labeled NO (Normally Open), C (Common), and NC (Normally
Closed). The three terminals make a single-pole, double-throw switch. The diagram below shows
how the terminals connect internally when the output is OFF. When the output is turned ON the C
contact switches from the NC position to the NO position.
