Surface-Mounted Automatic Alarm Switch with Lock Elektromet WGZ-1s (921490)

The Elektromet WGZ-1s surface-mounted automatic alarm switch with lock is designed to isolate circuits manually or automatically during alarm conditions in security, fire alarm and access control systems. Housed in a surface-mounted enclosure with an integrated mechanical lock, the unit provides a tamper-resistant method to interrupt or switch signaling circuits and power lines where a controlled break or manual override is required. The model supports secure operation for buildings and installations where clear circuit separation and dependable manual intervention are necessary.

Advantages

The WGZ-1s combines automatic alarm-triggered switching with a mechanical lock to prevent unauthorized operation while allowing authorized personnel to manually reset or isolate circuits. Its surface-mounted design simplifies installation on walls or panels without recessed fitting. The device is compatible with typical signaling and control wiring used in security and fire alarm systems and offers a reliable physical switching action for interrupting low-voltage circuits.

Suitable for

• Security system installations requiring protected manual circuit isolation
• Fire alarm systems where automatic circuit interruption is needed on alarm
• Access control setups that require secured override switches
• Commercial and residential buildings for signaling circuit management

Key specifications

• Surface-mounted enclosure for wall or panel installation
• Built-in mechanical lock for tamper resistance and controlled access
• Automatic switching action triggered by alarm input
• Manual override capability for authorized personnel
• Intended for low-voltage signaling and control circuits

How to use

Mount the WGZ-1s on a suitable flat surface and connect the incoming and outgoing control or signaling conductors according to the installation wiring diagram provided by the system designer or supplier. Ensure power to the associated control panels is isolated during wiring. In normal operation the switch remains closed or in the standby position; on alarm input it will operate automatically to interrupt or change circuit state. The mechanical lock prevents unauthorized manipulation—authorized staff use the corresponding key to manually isolate or reset the circuit when required.

Usage recommendations

Install the unit in accordance with applicable electrical and fire safety standards; verify compatibility with the control panel’s voltage and switching requirements before commissioning. Periodically test the mechanical lock and switching function as part of routine maintenance to ensure reliable operation during alarms.
