Entry and exit delays solve a simple problem: a security system needs to give an authorized person enough time to leave or disarm, without giving an intruder a generous head start. The right setting depends on the route, not just the house. A front door beside a keypad needs less time than a detached garage, a mudroom full of bags, or a route used by a child or someone with limited mobility.
This guide shows how to set delays by timing real routines, separating perimeter doors from instant-alarm zones, and testing the result before enabling professional monitoring. Menu names vary by brand, so confirm the exact behavior in your system’s app or support documentation.
The short answer
| Route or household | Starting point to test | What should decide the final setting |
|---|---|---|
| Main door with keypad nearby | 30 seconds | Time from opening the door to a successful disarm, plus a small buffer |
| Garage or mudroom entry | 45–60 seconds | Distance, locked interior door, packages, shoes, and keypad position |
| Children or frequent guests | 45–60 seconds | Whether they can disarm reliably without coaching |
| Older adult or mobility needs | 60 seconds or more if supported | The slowest normal trip through the route, not the fastest |
| Window, basement door, or unused side door | Instant alarm | Whether an authorized person ever enters through that opening |
These are test points, not universal recommendations. Start with the shortest delay that every authorized user can complete calmly and repeatedly. If a route consistently needs a long delay, moving the keypad or changing the normal entry door may be safer than adding more time.
Entry delay, exit delay, and instant zones
Entry delay starts when a delayed door opens while the system is armed. The alarm waits while the user reaches a keypad or phone and disarms. Exit delay starts when the system is armed and allows people to leave before sensors become active. An instant zone triggers without either grace period once armed.
Do not place every opening on the same delayed behavior. The front door and the door from an attached garage may need entry delay. A bedroom window, basement bulkhead, or rarely used side door usually does not. Keeping unused perimeter openings instant preserves faster detection without making everyday entry harder.
Map each real route before changing a setting
Walk the routes people actually take. Include the front door, garage, back door, and any route used by a dog walker, cleaner, relative, or short-term guest. Mark the first sensor that opens, where the disarm control is located, and what commonly slows the trip.
- Does the person need to unlock a second door?
- Do they stop to put down groceries, a child carrier, or work equipment?
- Can they hear the entry countdown from the first door?
- Is the keypad visible at night?
- Does the route depend on a phone that may be in a bag or out of battery?
- Can every authorized user complete the route without rushing?
Time five normal entries for each route. Use the slowest ordinary result, then add a modest buffer. Do not time a rehearsed sprint. The goal is a routine that works on a rainy evening with full hands, not a best-case demonstration.
Build a route worksheet
| Route | First sensor | Disarm point | Slowest normal time | Delay decision |
|---|---|---|---|---|
| Front door | Front contact sensor | Hall keypad | 22 seconds | 30-second entry delay |
| Garage | Door from garage | Kitchen keypad | 39 seconds | 45-second entry delay |
| Back patio | Patio contact sensor | None nearby | Not a normal entry | Instant alarm |
| Bedroom window | Window contact sensor | Not applicable | Never an entry route | Instant alarm |
Give sensors plain names that match the route. “Garage Entry Door” is more useful during an alert than “Sensor 7.” Our zone naming guide explains a room-and-opening naming system that also helps monitoring agents and emergency contacts understand what happened.
Keypad and hub placement can shorten delays
A keypad should be easy to reach after the delayed door opens but not visible or reachable from outside. If the only control is across the house, increasing the delay treats the symptom. Adding a second keypad or changing the entry route may reduce both stress and exposure time.
The hub has a different job. It needs reliable power, radio coverage, and a network connection, and it should not sit beside the entry door where it can be grabbed. See our home security hub placement guide before relocating it. A hub and keypad do not have to be in the same place.
Garage and mudroom routes need their own test
Garage entries are often the slowest. A person may wait for the overhead door, carry packages, pass through a locked fire door, and then reach a keypad in the kitchen. Treat the overhead garage door and the interior entry door as separate openings. Decide which one starts the countdown and test both a vehicle arrival and a pedestrian arrival.
Do not rely on a camera alone to start an entry delay. Cameras help verify activity, but direct contact sensors give a clear open-or-closed event. The garage security systems guide covers door contacts, tilt sensors, lighting, and camera placement for this higher-risk route.
Plan for children, guests, and accessibility
The setting must work for the slowest authorized user. Children may remember a code but hesitate when a countdown sounds. Older adults may need more time to see keypad buttons. A guest may enter through the wrong door. Test with each person rather than assuming one adult’s timing represents the household.
- Give each regular user a separate code when the system supports it.
- Avoid sharing the owner account or master code with temporary visitors.
- Show guests exactly which door has a delay and which doors are instant.
- Keep the route lit and free of bags, shoes, and trip hazards.
- For phone-based disarming, keep a keypad fallback for a dead battery or service outage.
If someone cannot complete the routine consistently, change the route, add a control point, or lengthen only that delayed zone if the system permits per-zone timing. Do not weaken every perimeter opening to solve one route.
Reduce false alarms without hiding real ones
Too little time causes rushed code entry and accidental dispatches. Too much time slows escalation after a real break-in. False-alarm prevention also depends on sensor alignment, clear alerts, current contact details, user training, and knowing the cancellation process. Work through the false-alarm reduction checklist before assuming delay length is the only cause.
Professionally monitored households should confirm what happens after the delay expires: whether there is a verification call, in-app cancellation, video verification, or immediate dispatch under local rules. Abode, for example, offers self-monitoring and professional-monitoring choices on its plans page; the exact alarm workflow depends on the selected plan and current account setup.
Test power, internet, and phone failures
An entry routine that works only when Wi-Fi and a phone are available is fragile. With the system in test mode, disconnect the home internet and confirm whether the keypad can still disarm locally. Check hub battery backup, cellular backup if included with the plan, and whether the countdown tone still sounds. The security system setup checklist has a broader acceptance test for connectivity, alerts, and backup behavior.
Also check what happens if the user enters a wrong code, closes the door after entering, or opens a second instant-zone door during the countdown. Systems do not all handle these events the same way.
Run a 20-minute acceptance test
| Test | Pass condition | If it fails |
|---|---|---|
| Normal exit | Everyone clears the final door before arming completes | Change exit route, placement, or delay |
| Normal entry | Each user disarms calmly before the timer expires | Retest placement and route before adding time |
| Wrong code | User understands retry and cancellation steps | Train users and confirm lockout behavior |
| Instant-zone opening | Unused perimeter opening alarms immediately | Correct the zone type |
| Internet disconnected | Local disarm still works and backup behavior is known | Add a keypad or review backup options |
| Garage arrival | Vehicle and pedestrian routes both fit the plan | Separate the routes or add a closer control |
Put a professionally monitored system into test mode before triggering alarms, and tell other household members what you are doing. After testing, restore monitoring, clear any bypassed sensors, and verify the armed state.
Bottom line
Set entry and exit delays from measured routes. Delay the doors people genuinely use, keep unused perimeter openings instant, and fix poor keypad placement before stretching every timer. Then test with every authorized user, including garage arrivals and an internet outage. A good setting is the shortest one the whole household can complete without rushing.
Frequently asked questions
How long should a home security entry delay be?
Time the real route from the delayed door to a successful disarm, use the slowest normal result, and add a small buffer. Thirty seconds may suit a nearby keypad, while a garage or accessibility route may need 45–60 seconds or more if the system supports it.
Should every door have the same entry delay?
No. Only normal entry routes usually need a delay. Windows, basement doors, and unused side doors should normally remain instant zones when armed, subject to the system’s options and the household’s needs.
Can a camera replace a door sensor for entry delay?
A camera can add visual verification, but a direct contact sensor gives a clearer door-open event. Use the camera as a second source of context rather than the only trigger for a normal entry route.
What happens to entry delay when the internet is down?
That depends on the system. Many hub-and-keypad systems can still arm and disarm locally, while remote alerts or monitoring communication may depend on cellular backup. Test the exact behavior in test mode and keep a keypad fallback for phone-based routines.
