EMX CHIME-100 Auditory Alert System
Instruction Manual
The CHIME-100 is an accessory device that produces a very loud audible notification when activated. Its maximum volume can exceed 100dBA at 5ft, which is easily heard even in environments with high background noise. It includes six selectable melodies, an easily adjustable volume, passthrough power outputs to run other peripherals, such as sensors or visual alert devices, an output relay, and an input which only requires a set of dry contacts for activation. Intended for indoor use only.
Cautions and Warnings
- Maximum volume in close proximities may exceed 100dBA, which can result in permanent hearing damage.
- When drilling, ensure no damage can be caused in desired mounting location, e.g. hidden wires, waterlines, etc.

Installation
- In the desired location, mount the CHIME-100 housing using at least two screws.
- Unscrew the lid of the housing and carefully remove the lid.
CAUTION: The lid and base are attached by the speaker’s wires. Excess force could damage the unit
-
Mount the cable-grip in the large hole in the bottom of the housing by inserting it from the outside, then screwing on and tightening the nut from the inside.
-
Wire all needed connections on the device. See sections “Outputs” & “Inputs” for a detailed description of each terminal’s function. The CHIME-100 requires a connection between INPUT 1 and INPUT 2 to properly function.
Connection| Description
---|---
VOUT –| Negative connection from power jack in. Can be used to power other low-power devices. (Power adapter included is 9VDC)
VOUT +| Positive connection from power jack in. Can be used to power other low-power devices. (Power adapter included is 9VDC)
INPUT 1| Closing the connection between these inputs will trigger the melody. It can be connected to a relay, switch, pushbutton, transistor, etc.…
INPUT 2
NPN OUT| An open collector transistor output which will pull down to ground when activated. This output can handle 170mA at 100VDC
RELAY OUT| NC| Normally-closed output connection
COM| Common output connection
NO| Normally-open output connection -
All wiring should pass through the cable grip. Tighten down the cable grip once wiring is complete.
-
Check that the inputs are being properly recognized. The red Presence LED (see below) will turn on when the input is activated. If the input shorting lasts longer than 30 seconds, the presence LED will begin blinking.
-
Configure the CHIME-100 to play the desired melody by pressing the pushbutton on the side of the unit. Adjust the volume to a comfortable level. See section “Chime Adjustment” on next page for more information.
-
Reattach the lid to the base and screw down firmly. Test the setup again to ensure the correct chime plays at a comfortable listening level.
Chime Adjustment
Volume To adjust the volume of the CHIME-100, use the “Volume Adjustment Knob” sticking out of the housing’s side. See the table below.
| Direction | Volume |
|---|---|
| Clockwise | Louder |
| Counter-clockwise | Quieter |
Chime
The melody that is played when the input is activated can be changed by
pressing the “Chime Select Button” on the side of the unit. Each time the
button is pressed, the next melody is selected and played. There is a total of
six different melody options. The selected melody will be remembered through
power-down.
Inputs
INPUT 1 & 2
The CHIME-100 will activate when terminal INPUT 1 is shorted with terminal
INPUT 2. The device used to short these terminals together can be anything
that closes a circuit (e.g. relay contacts, transistor, light switch,
pushbutton, etc).
Outputs
-
VOUT
The CHIME-100 comes with a 9VDC power adapter that plugs into the unit via barrel jack, and is powered through a wall outlet. This power supply can be used to power additional peripherals through the VOUT terminals. If using the included power adapter, the additional peripherals should draw no more than 400mA of current. -
RELAY
A set of form C relay contacts (normally open, common, and normally closed), which can handle 2A, and 250VAC or 220VDC. This relay will switch states when INPUT1/INPUT2 activates the CHIME-100. -
NPN
An open collector transistor output will pull down to ground when activated. This output can handle 160mA, and 100VDC. This transistor will switch states when INPUT1/INPUT2 activates the CHIME-100.
Troubleshooting
| Symptom | Possible Cause | Solution |
|---|---|---|
| CHIME-100 does not play melody | Volume is at minimum | Rotate Volume Adjustment |
Knob clockwise.
| The input is not connected properly| Verify wiring to terminals INPUT 1 and
INPUT 2. Verify presence LED turns on when the input terminals are shorted
together.
| Speaker wires damaged or disconnected.| Verify both speaker wires are
properly connected to the board via connector labeled “ SPEAKER ”
No Green Power LED| No power Incoming voltage is too low| Using a DMM, check
the voltage across terminal VOUT + and VOUT –. Verify this voltage is
at least 9VDC. If voltage is low, replace the power supply or wire in 3rd
party 9VDC supply into the VOUT terminals.
CHIME-100 presence LED does not activate when input terminals are shorted
together.| Poor Wiring Activation source| Verify wiring connections to INPUT 1
and INPUT 2 terminals. Verify the activation source is shorting together INPUT
1 and INPUT 2 terminals by using a DMM set to read Ohms (Ω) and ensuring that,
when activated, the inputs are reading under 25kΩ.
NPN output not working| Damaged from current overload| Unit is damaged and
will need to be repaired or replaced.
