Installation Steps
Step 1: Mounting the Netbell-4 Controller
1. Choose a dry, indoor location for installation
2. Using the provided mounting brackets:
– Attach mounting brackets to the SERVER using
provided self-tapping screws (4 places)
– Install the SERVER at desired location using
appropriate screws for your wall type
– Ensure adequate ventilation around the unit
Step 2: Buzzer Wiring Instructions
Relay Output Specifications:
- Four relay outputs for controlling timed signal
equipment, labeled as EXT1 to EXT-4
- Dry Contact type (1-Form-A relay)
- Maximum rating: 48VAC @ 8A per relay
- Normally Open (NO) contacts, convertible to NC if
needed
Buzzer Wiring Steps:
1. Buzzer Mounting and Cable Requirements:
-
Mount the pre-wired buzzer kit at the location you
would like to have your buzzer
-
You can extend the power cable of the buzzer if
needed
-
Buzzer can be installed at 500 feet away from
controller using 16AWG cable
2. Basic Connection Setup: the relays on the Netbell-4
K are dry contact relay with CP connector and four
bell cables (3FT) come with your Netbell-4K.
– Connect CP connector side of bell cable to one of
the bell outputs (EXT1 to EXT4)
– Connect one power source wire to one side of the
buzzer
– Connect other power wire to one side of the bell
cable
– Connect remaining buzzer wire to other side of bell
cable
– Repeat wiring process for all four buzzers
3. Multiple Buzzer Configuration:
- Each relay can control devices up to 8A total current
- Total current draw of all connected buzzers must
not exceed 8A
- Ensure power supply rating matches total buzzer
current requirements
- Verify total current draw is within specifications
before operation
IMPORTANT NOTES:
- This device is NOT designed to directly switch line
voltage (120V/240V)
- For line voltage devices, an intermediary relay
MUST be installed
- Verify all connections before applying power
- You can install the buzzer at up to 500 ft away from
the controller using 16 AWG 2-conductor wire
- Use appropriate wire gauge for current rating
