If you're replacing a Honeywell 5800MINI or 5816 door/window sensor, the Versa Wireless MINI-345 installs on any panel that accepts 5800-series sensors — same 345 MHz frequency, same loop number, no hardware changes needed. This guide covers the exact enrollment steps for the three most common 345 MHz panels: the Honeywell VISTA 20P, the Resideo PROA7/PROA7PLUS, and the 2GIG EDGE.
Honeywell VISTA 20P
What You Need
- VISTA 20P with a compatible 5800-series RF receiver installed (5881ENH, 5883H, 6160RF, or similar)
- Installer code (factory default:
4112) - MINI-345 7-digit serial number (from label inside sensor cover)
- Alpha keypad (6160 or similar) for entering zone descriptors
About Wireless Zones on the VISTA 20P
The VISTA 20P supports up to 40 wireless transmitter zones (zones 9–48) through an external 5800-series receiver. Each sensor is identified by its unique 7-digit serial number and loop number. The MINI-345 magnetic contact uses Loop 1.
Programming uses *56 Zone Programming Mode (interactive, keypad-guided). The full data field reference is in the VISTA 20P Programming Guide, which is separate from the Installation Guide.
Enter Programming Mode
At the keypad, press your installer code followed by *56:
4112 *56
The keypad will display PROGRAM MODE and prompt you to enter a zone number.
Select the Zone Number
Enter a 2-digit zone number between 09 and 48 (wireless zone range on the VISTA 20P), then press [*]. Choose a zone that isn't already assigned to another sensor.
Set Input Type: Supervised RF
At the INPUT TYPE prompt, press [0] then [3] to select Supervised RF (3). Press [*] to advance. This tells the panel to expect a wireless transmitter and enables the serial number and loop fields.
Enter the Serial Number
Type the full 7-digit serial number from the MINI-345 label. Press [*]. Double-check this number — a single wrong digit means the panel won't recognize the sensor's transmissions.
Enter Loop Number 1
At the loop prompt, press [1], then [*]. Loop 1 is the magnetic contact input — the zone that triggers when the door or window opens.
Set Zone Type
Enter the appropriate 2-digit zone type for this sensor's location:
- 04 — Entry/Exit 1 (primary entry door with entry delay)
- 05 — Entry/Exit 2 (secondary door, longer delay)
- 03 — Perimeter (instant alarm — windows, back doors)
Press [*].
Enter a Zone Descriptor (Optional)
On an alpha keypad, type a label for this zone (e.g., FRONT DOOR, GARAGE DR). This displays on the keypad during alerts. Press [*] to save.
Exit Programming Mode
Press *99 to exit *56 mode and return the panel to normal operation.
Verify Enrollment with RF Sniffer Mode
Confirm the sensor's serial number is enrolled and transmitting:
- From a partition-1 keypad, enter
Installer Code + [#] + [3](e.g.,4112 #3) to enter RF Sniffer mode. - Open and close the door or window with the MINI-345 installed.
- Sniffer mode checks that each enrolled transmitter's serial number has been received; when the MINI-345 reports, its zone clears from the not-yet-seen list.
- Sniffer mode does not time out — exit by entering
Installer Code + OFF(e.g.,4112 + OFF) to return to normal operation.
Installer Code + [#] + [4] (e.g., 4112 #4). This mode reduces the receiver's gain, so if the panel still receives the MINI-345 when you trip it, you have enough signal strength to mount there. Exit with Installer Code + OFF.
Resideo PROA7 / PROA7PLUS
What You Need
- PROA7 or PROA7PLUS control panel
- PROTAKEOVER wireless converter module — rotary switch set to 0 (5800); install the replacement wall mount with integrated antenna that ships with it
- AlarmNet 360 account (AlarmNet 360 login)
- MINI-345 7-digit serial number
- Laptop, tablet, or phone with internet access
About Programming on the PROA7
Unlike the VISTA 20P, the PROA7 has no local keypad programming mode for sensors. All zone configuration is done through AlarmNet 360 — Resideo's cloud-based programming portal — and syncs automatically with every change. The panel supports up to 250 total wireless zones (up to 127 of which can be PROSiX/SiX); the 5800-series sensors received through the PROTAKEOVER share that same zone pool.
Log into AlarmNet 360
On a laptop, tablet, or phone, go to AlarmNet 360 or open the AlarmNet 360 app. Open the customer's account.
Navigate to Zones / Sensors
From the account programming menu, select Devices or Zones, then choose an available zone slot.
Put the Panel Into Learn Mode
In AlarmNet 360, select Learn Mode for the zone you're programming. The panel is now listening for a new sensor's RF transmission.
Enroll the MINI-345
Open and close the door or window where the MINI-345 is installed. The panel receives the RF signal and captures the serial number automatically. Alternatively, enter the 7-digit serial number manually in the TXID field.
Configure Zone Settings
In AlarmNet 360, set the following for this zone:
- Zone Type — Entry/Exit, Perimeter, etc.
- Zone Name/Descriptor — e.g., Front Door
- Supervision — enabled (default); the panel will expect check-ins every 70–90 minutes
Save — Sync Is Automatic
The PROA7 syncs programming changes automatically. No manual download is required. Confirm the sensor appears under Menu → Sensors on the PROA7 touchscreen or in AlarmNet 360 with a valid signal strength reading.
2GIG EDGE
What You Need
- 2GIG EDGE panel
- Installer code (factory default:
1561) - MINI-345 7-digit serial number (TXID from label inside sensor cover)
About Wireless Zone Programming on the 2GIG EDGE
The 2GIG EDGE uses a guided programming system accessed through the Installer Toolbox on the 7" touchscreen. Each wireless zone has its own set of parameters: equipment type, TXID (serial number), loop number, zone type, voice descriptor, and supervision settings.
Enter the Installer Toolbox
On the EDGE touchscreen, navigate to:
System Settings → Installer Toolbox → Enter Installer Code
Go to Panel Programming → Wireless Zones
From the Installer Toolbox, select Panel Programming, then Wireless Zones. Tap the zone slot you want to program.
Set Sensor / Equipment Type
Select the equipment type for the MINI-345. Choose Door/Window (DW) Contact from the sensor category list. Refer to the Sensor Equipment Type list in the EDGE programming menu for the matching thin door/window contact entry.
Enter the TXID (Serial Number)
Tap the TXID field and enter the 7-digit serial number from the MINI-345 label.
Or use Auto-Learn / Shadow Learn: Select Learn, then open and close the door or window. The panel captures the sensor's TXID automatically from the RF transmission.
Set Loop Number to 1
Select Loop 1. This is the magnetic contact input on the MINI-345 — the loop that activates when the door or window opens.
Set Zone Type
Choose the zone response type based on this sensor's location:
- Entry/Exit 1 — front door (entry delay active)
- Entry/Exit 2 — secondary door (longer entry delay)
- Perimeter — windows, back doors (instant alarm)
Set Voice Descriptor
Choose a name from the EDGE's vocabulary list (e.g., Front Door, Garage Door). The panel announces this name during alarms and chime events.
Confirm Reports and Supervision
Leave Sensor Reports and Sensor Supervised enabled (default settings). The panel will check in with the sensor periodically and flag a trouble condition if supervision signals are missed.
Test and Save
From the Installer Toolbox, run a Sensor Test (walk test). Open and close the door or window — the panel should display the zone name and register the event. Verify signal strength before permanently mounting the sensor. The EDGE saves changes when you exit programming.

Frequently Asked Questions
What loop number do I use for the MINI-345?
Use Loop 1 on all three panels. Loop 1 is the magnetic contact input — the zone that activates when the door or window opens.
Can I swap in a MINI-345 without re-programming the panel?
No. Every sensor has a unique serial number (TXID), so you'll need to delete the old 5800MINI from the panel and enroll the MINI-345 with its new serial number. The zone number, zone type, and descriptor can stay the same — only the TXID changes. See our 5800MINI replacement guide for a broader look at swapping 5800-series sensors.
Does the PROA7 work with 345 MHz sensors like the MINI-345?
Not on its own — the PROA7/PROA7PLUS natively uses PROSiX/SiX (2.4 GHz). Add the PROTAKEOVER module (rotary switch set to 0 for the 5800 protocol) to receive the MINI-345's 345 MHz signal. The module adds legacy 319.5/345/433 MHz reception without disabling the built-in PROSiX/SiX receiver, so your existing PROSiX sensors keep working — the panel supports up to 250 total wireless zones.
Where is the serial number on the MINI-345?
Open the sensor cover — the 7-digit serial number is printed on a label inside the housing. It may also appear on the outside of the packaging box.
