The short answer
Arrow’s public site does not state a universal startup time, and a responsible security company should not promise one without reviewing the assignment. Start time depends on the location, schedule, number of officers, armed or unarmed status, required experience, contract approval, post orders, site orientation, equipment, and whether the need is one shift or ongoing coverage.
What to know
A simple unarmed post with clear duties and reasonable notice may be easier to staff than multiple 24/7 armed posts, a remote location, a healthcare assignment, or an event requiring specialized coordination. An urgent request still needs basic safeguards: verified client authority, accurate address, emergency contacts, lawful duties, hazard information, officer check-in, escalation rules, and a written scope. Skipping those steps to appear fast can create greater risk.
To get the quickest reliable answer, send the exact start date and time, site address, daily schedule, number of posts, duties, known hazards, armed or unarmed preference, expected duration, and decision-maker contact. Ask Arrow to distinguish the earliest feasible temporary deployment from the timeline for a stable long-term team. The contract should not use “immediate,” “rapid,” or “emergency” as an unqualified response-time promise. Confirm who will communicate updates if staffing or site readiness delays the start.
