Setup
Transmitter Installation
- Power Connection: Connect the transmitter to a 12VDC power source. Ensure proper polarity.
- Antenna Connection: Connect the provided radio antenna adapter cord to the transmitter. For optimal range, consider connecting to a CB antenna, car AM radio antenna, or the optional E-37ANT external antenna. Ensure the antenna body is properly grounded for best performance.
- Trigger Inputs: Connect the alarm system's trigger outputs to the transmitter's one positive and two negative instant trigger inputs. Refer to your alarm system's manual for specific wiring instructions.
Receiver Setup
- Battery Installation: The receiver requires two AAA batteries (not included). Open the battery compartment and insert the batteries, observing correct polarity.
- Code Learning: The receiver is designed to learn up to three transmitter codes. Follow the specific instructions provided with the product for the code-learning procedure. This typically involves activating the transmitter while the receiver is in a learning mode.
- Mode Selection: Select between audible or vibration page indication using the switch on the receiver.
Operation
Manual Paging
The system supports manual paging. Consult the specific product documentation for instructions on how to initiate a manual page from the transmitter, if applicable.
Zone Indication
When an alarm is triggered, the receiver's color LEDs will illuminate to indicate which zone was activated:
- Green LED: Indicates Zone 1 trigger.
- Orange LED: Indicates Zone 2 trigger.
- Red LED: Indicates Zone 3 trigger.
Page Recall
The receiver stores the last six pages received. Use the recall function (refer to receiver buttons) to review previous alerts.
Unattended Page Indicator
If a page is received and not acknowledged, the receiver will provide an unattended page indication (e.g., a flashing LED or repeated alert) until it is cleared.
Low Battery Indicator
The receiver features a low battery indicator to alert you when the AAA batteries need replacement.
Maintenance
Battery Replacement
When the low battery indicator activates on the receiver, replace the two AAA batteries promptly. Ensure correct polarity during installation.
Cleaning
Clean the units with a soft, dry cloth. Avoid using abrasive cleaners or solvents, which may damage the casing or internal components.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No page received | Receiver batteries low or dead | Replace receiver batteries. |
| No page received | Transmitter not powered | Check 12VDC power connection to the transmitter. |
| No page received | Transmitter not triggered | Verify alarm system trigger output is connected correctly and functioning. |
| Reduced range | Poor antenna connection or grounding | Ensure antenna is securely connected and properly grounded. Avoid obstructions. |
| Receiver not responding to transmitter | Receiver not coded to transmitter | Perform the code-learning procedure for the receiver. |
