Wall-mounted automatic alarm switch Elektromet WG-1s (model 921440) — single-channel surface-mounted emergency switch

Electromet WG-1s is a wall-mounted automatic alarm switch designed for surface installation. This single-channel surface-mounted emergency switch provides a reliable method to interrupt or activate connected alarm circuits either automatically or by manual intervention. Intended for use in alarm and safety systems in buildings, industrial premises, and other facilities, the device is engineered to perform as a dedicated, easy-to-install switching element for emergency signalling and circuit control.

Advantages

The WG-1s offers a compact, surface-mounted design that simplifies installation on walls without the need for flush mounting. Its single-channel configuration ensures straightforward wiring and integration into existing alarm circuits. The unit supports both automatic triggering and manual actuation, giving flexibility in different safety scenarios. Constructed for continuous readiness, the switch is suitable for indoor environments where a visible and accessible emergency switching device is required.

Suitable for (tasks / use cases)

• Activation or interruption of alarm circuits in commercial and residential buildings
• Emergency switching in industrial premises and warehouses
• Integration into fire alarm and security systems requiring a surface-mounted control point
• Use as a local manual override or automatic trigger point within a monitored safety system

Key specifications

How to use

Install the WG-1s on a suitable wall surface using appropriate fasteners and routing for wiring according to local electrical codes and the system design. Connect the incoming and outgoing alarm circuit conductors to the device terminals following the installation diagram provided by the system integrator or installation documentation. The unit can be set to operate automatically as part of a monitored alarm system or left accessible for manual actuation to interrupt or activate the alarm circuit when necessary. After installation, perform functional tests to verify correct switching behaviour and integration with the overall alarm system.

Usage recommendations

Place the switch in a clearly visible and accessible location that complies with applicable safety regulations. Verify compatibility with the alarm system's voltage and signalling standards before connection. Schedule periodic inspections and functional tests to ensure reliable operation and maintain system readiness.
