Setup and Installation
1. Powering the Keypad
The 5828 keypad can be powered by batteries or an optional AC adapter.
- Battery Installation: Open the battery compartment on the back of the keypad. Insert the required batteries (typically AA, refer to the keypad's battery compartment for exact type and quantity), ensuring correct polarity. The keypad will power on.
- AC Adapter (Optional): If using an AC adapter (e.g., Honeywell K0991, sold separately), connect it to the power jack on the keypad and plug it into a standard wall outlet. Using an AC adapter allows the keypad display to remain active continuously, unlike battery-only operation where the display may go to sleep to conserve power.
2. Mounting the Keypad
Choose a suitable location for your keypad, typically near an entry/exit point. Ensure it is within wireless range of your main alarm control panel.
- Wall Mounting:
- Carefully detach the back plate from the keypad unit.
- Hold the back plate against the wall at the desired height and mark the screw hole locations.
- Drill pilot holes if necessary and insert wall anchors.
- Secure the back plate to the wall using the provided screws.
- Align the keypad unit with the mounted back plate and snap it into place.
- Desk Mounting (Optional): An optional desk mount (P/N 5828DM) is available for tabletop placement. Follow the instructions provided with the desk mount accessory.

3. Enrolling the Keypad with Your Alarm System
The 5828 is a wireless device and must be enrolled (programmed) into your compatible Honeywell alarm control panel (e.g., LYNX series) before it can function. Refer to your main alarm system's installation manual for detailed instructions on enrolling wireless devices. This typically involves:
- Putting the control panel into programming mode.
- Entering the keypad's serial number (located on the back of the unit).
- Assigning a zone or device type to the keypad.
- Testing communication between the keypad and the control panel.
Consult a professional installer if you are unsure about the enrollment process.
