Product Overview
Figure 1: Alarm Controls TS-20D Under Desk Push Button. This image shows the compact design of the push button, typically featuring a durable casing and the push button mechanism itself, designed for discreet mounting.
The TS-20D is an alternate action (latching) push button switch. This means that when the button is pressed, it latches into the "ON" position, and remains there until pressed again to return to the "OFF" position. It features Double Pole Double Throw (DPDT) contacts, providing two independent sets of Normally Open (NO) and Normally Closed (NC) contacts, allowing for versatile wiring configurations.
- Push Button: The primary interface for activation.
- Mounting Flange/Bracket: For secure installation under a desk or similar surface.
- Terminal Block: For electrical connections (typically screw terminals).
Setup and Installation
Follow these steps for proper installation of the TS-20D:
- Choose Mounting Location: Select a discreet and secure location under a desk, counter, or similar surface. Ensure there is sufficient space for the button and wiring, and that the surface material can hold the mounting screws.
- Prepare Wiring: Disconnect all power to the circuit where the TS-20D will be connected. Identify the wires for your application (e.g., power, control signal, common).
- Mount the Button:
- Position the TS-20D in the desired location.
- Mark the screw hole locations using a pencil.
- Drill pilot holes if necessary, appropriate for the mounting screws and surface material.
- Secure the TS-20D using the provided mounting screws. Do not overtighten.
- Wire the Contacts: The TS-20D features DPDT contacts. Refer to the wiring diagram specific to your application.
A DPDT switch has 6 terminals: two common (COM), two normally open (NO), and two normally closed (NC). When the button is in its default (unpressed) state, COM is connected to NC. When pressed, COM connects to NO.
- Connect your input signal to the Common (COM) terminals.
- Connect your output/controlled device to either the Normally Open (NO) or Normally Closed (NC) terminals, depending on whether you want the circuit to be active when the button is pressed (NO) or released (NC).
- Ensure all connections are secure and insulated.
- Test Operation: Once wiring is complete and secure, reapply power to the circuit. Test the button's functionality to ensure it operates as expected for your application.
Operating Instructions
The TS-20D is an alternate action (latching) push button. Its operation is straightforward:
- To Activate: Press the button firmly. The button will click and remain in the depressed position, changing the state of its DPDT contacts.
- To Deactivate: Press the button firmly again. The button will click and return to its original extended position, reverting the state of its DPDT contacts.
The specific action (e.g., locking/unlocking a door, activating/deactivating an alarm) depends on how the DPDT contacts are wired into your system.
Maintenance
The TS-20D is designed for long-term, reliable operation with minimal maintenance.
- Cleaning: If necessary, gently wipe the button and casing with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Inspection: Periodically check the mounting screws for tightness and the wiring connections for security.
- Avoid Obstruction: Ensure no objects obstruct the button's movement.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Button does not latch/unlatch | Internal mechanism issue or obstruction. | Ensure no physical obstruction. If issue persists, the unit may be faulty and require replacement. |
| Device not responding to button press | Incorrect wiring, loose connections, or no power to the controlled device. | Verify all wiring connections are secure and correct according to your system's diagram. Check power supply to the controlled device. |
| Button feels loose or wobbly | Loose mounting screws. | Tighten mounting screws. Do not overtighten. |
