✕Common Mistakes
Installe une système d'alarme.
Système is masculine, so the correct article is un, not une.

Installez is the formal/plural imperative; using it with a single informal person sounds overly formal.
Installe un système de alarme.
Do not separate the contraction; it must stay attached to the following noun.

Cultural Tip
In French the imperative drops the subject pronoun. Use Installe for an informal singular ‘you’, and Installez for a formal singular or plural audience. The phrase système d'alarme is the standard term for a home‑security system; avoid translating it literally as ‘alarm system’ in English‑only contexts, as the French expression carries a technical nuance.
