Setup and Installation
The TS-18 push button is designed for surface mounting. Proper installation is crucial for reliable operation. It is recommended that installation be performed by a qualified technician, especially when connecting to existing electrical systems.
Installation Steps:
- Choose Mounting Location: Select a flat, stable surface, such as the underside of a desk or counter, where the button will be easily accessible but protected from accidental activation.
- Secure the Unit: Use appropriate screws (not included) to securely fasten the TS-18 to the chosen surface. Ensure the unit is firmly attached to prevent movement during operation.
- Wiring:
- Identify the appropriate wiring terminals on the TS-18. As an SDT (Single-Pole, Double-Throw) switch, it typically has common, normally open (NO), and normally closed (NC) terminals.
- Connect the control wires from your system (e.g., access control panel, alarm system) to the corresponding terminals on the TS-18. Refer to your system's documentation for specific wiring requirements.
- Ensure all connections are secure and properly insulated to prevent short circuits.
- Test Functionality: After installation and wiring, test the button's operation with the connected system to confirm it functions as intended.
Important: Always disconnect power to the system before performing any wiring to prevent electrical shock or damage to components.
Operating Instructions
The TS-18 is a momentary push button. Its operation is straightforward:
- Activation: Press the button firmly. The internal switch contacts will change state (e.g., Normally Open contacts will close, Normally Closed contacts will open) for as long as the button is held down.
- Deactivation: Release the button. The internal switch contacts will return to their original state.
The specific action triggered by pressing the button (e.g., unlocking a door, activating an alarm) depends on the system to which the TS-18 is connected.
Maintenance
The Alarm Controls TS-18 push button requires minimal maintenance to ensure long-term reliability.
- Cleaning: Periodically wipe the surface of the button with a soft, dry cloth to remove dust and debris. Avoid using abrasive cleaners or solvents, which may damage the finish.
- Inspection: Annually inspect the mounting screws and wiring connections to ensure they remain secure. Check for any signs of wear or damage to the button or its housing.
- Functionality Check: Periodically test the button's operation to confirm it activates the connected system reliably.
