Product Components
The ERA-DOOR ALARM system typically includes the following components:
- ERA Receiver Unit: The main unit that produces the chime/siren and activates the strobe.
- Wireless Push Button Transmitter: For manual activation of the chime/alarm.
- Magnetic Door Contact Sensor: Detects when a door or window is opened.
- Flashing Strobe/Siren Unit: Provides visual and audible alerts.
- Mounting hardware and batteries (CR2 battery for transmitters, power adapter for receiver).

Setup and Installation
1. Receiver Placement and Power
Place the ERA Receiver Unit in a central location within your desired alert area. Ensure it is within range of all planned transmitters. Plug the receiver into a standard electrical outlet using the provided power adapter.
2. Transmitter Battery Installation
For the wireless push button and magnetic contact sensor, install the included CR2 battery. Open the battery compartment, insert the battery with the correct polarity, and close the compartment securely.
3. Mounting the Push Button
Mount the wireless push button near the entry point where it will be used. Use the provided screws or adhesive tape. Ensure the mounting surface is clean and dry for adhesive application.

4. Mounting the Magnetic Door Contact Sensor
Install the magnetic contact sensor on a door or window frame. The main sensor unit should be mounted on the stationary frame, and the smaller magnet unit on the moving part (door/window). Ensure the two parts are aligned and within 1/2 inch of each other when the door/window is closed. Use screws or adhesive for secure mounting.

5. Pairing Transmitters with the Receiver
The system allows pairing up to 12 Safeguard Supply ERA transmitters. Refer to the receiver's specific instructions for pairing mode. Typically, this involves pressing a pairing button on the receiver, then activating the transmitter (pressing the push button or opening the door with the contact sensor) to link them.
Operating Instructions
1. Basic Operation
Once transmitters are paired, the receiver will emit an alert (chime or siren) and activate the flashing strobe when a paired transmitter is triggered. For example, pressing the wireless push button or opening a door with a magnetic contact sensor will activate the alert.

2. Adjusting Settings
- Volume Control: The receiver unit typically has buttons or a dial to adjust the alert volume.
- Chime/Siren Selection: Some models allow selection between different chime melodies or a siren sound. Consult your receiver's specific controls for this feature.
- Strobe Activation: The flashing strobe unit activates simultaneously with the audible alert.
Maintenance
1. Battery Replacement
Transmitters (push button, door contact sensor) are powered by CR2 batteries. Replace batteries when the signal range decreases or the unit stops functioning. The average battery life is approximately 2 years. To replace, open the battery compartment, remove the old battery, insert a new CR2 battery with correct polarity, and close the compartment.
2. Cleaning
Wipe the units with a soft, dry cloth. Do not use abrasive cleaners or immerse units in water.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Receiver does not alert when transmitter is triggered. |
|
|
| Alert is too quiet or too loud. | Volume setting is incorrect. | Adjust the volume control on the receiver unit. |
| False alarms from door contact sensor. | Magnet and sensor misaligned or too far apart. | Re-align and re-mount the sensor and magnet to ensure they are within 1/2 inch when closed. |
