Detex AT-5600-R0 – Frequently Asked Questions

1) Will a Detex AT-5600 tailgate detector fit our existing door frame, and is there a width limit?
The AT-5600 mounts on standard width door frames or on the adjacent wall, with a maximum opening width of 80 inches. Anything wider than 80 inches is outside what the infrared beam array covers, so a wide vestibule or a double-door opening beyond that width needs a different approach.
2) Can we add tailgate detection to the card access system we already have, or do we have to replace the readers?
No reader replacement. The AT-5600 is built to retrofit onto existing access control and is compatible with most card reader technologies, so it wires in alongside the reader you already run. It ties into the access control system per the wiring diagrams in the Detex installation instructions.
3) What is the difference between the Spacer Kit yes and no options on the AT-5600?
The spacer mounting kit acts as a raceway for the wiring behind the unit. Order it when you are surface mounting and have no concealed path for conductors, which is the usual case on an existing frame or a masonry wall. If the frame is already prepped and wire can be pulled inside it, the no-spacer version is what you want.
4) Which status indicator mounting plate should I order with the AT-5600, single-gang or mullion?
Three choices: a single-gang mounting plate, a mullion mounting plate, or no indicator at all. Pick single-gang where the indicator lands in a standard electrical box beside the opening. Pick mullion where it mounts on the narrow vertical member between a pair of doors or on a storefront mullion, which is too narrow for a single-gang plate. Choose No if the alarm annunciation and status relay are enough and you do not need a visible indicator at the door.
5) How long does the AT-5600 alarm sound, and does someone have to reset it?
The alarm runs a 3 second fixed time voice message and then auto resets. Nobody has to walk to the door with a key or push a reset button, which is why it suits an unattended employee entrance or a dorm door where staff are not standing by.
6) Does a tailgate detector like the AT-5600 also catch a door left propped open?
Yes, door prop alarm is integrated into the AT-5600, so you get propped-door annunciation from the same unit rather than adding a separate door position monitor. It also carries a tamper switch to flag attempts to disable the detector.
7) Can our security office get notified when the tailgate alarm trips, or is it only audible at the door?
Both are possible. The digital voice annunciator sounds locally at the opening, and an alarm status relay is provided for remote annunciation, so you can carry the signal back to a head end, panel, or guard station.
8) Will a tailgate detection system at the entry create an accessibility problem for our building?
The AT-5600 is ADA compliant, and it is an optical detector, so it does not add a turnstile, gate, or physical restriction in the path of travel. Authorized users keep moving at normal throughput.
9) Does the AT-5600 monitor people leaving as well as entering?
That is a field setting. The unit configures for card in / card out, where a credential is required in both directions, or card in / free exit, where egress is unrestricted. The access period is also adjustable, so you can widen the window for a slower-moving population or tighten it on a high security room.
10) What does the AT-5600 actually do differently from a standard card reader and door contact?
A reader confirms a valid credential; it cannot tell how many people walked through on that read. The AT-5600 uses infrared sensor beams and detection algorithms to count passage against the authorized read, so a second person following on one card triggers the voice alarm. Pair it with the reader you already have rather than treating it as a replacement.
11) Is the Detex AT-5600 suitable for a residential apartment entry, or is it a commercial-only product?
It is a commercial product. Detex lists the AT-5600 as commercial, and the intended applications are employee entrances, computer rooms, bank vaults, dormitory entrances, healthcare facilities, and government buildings. A single-family or small residential entry is not what it is built around.
