Alarm Controls KP-400 – Frequently Asked Questions

1) Can the Alarm Controls KP-400 keypad be mounted outside on an exterior door?
Yes. The KP-400 is built for outdoor service: a black powder coated die cast aluminum back box, 302 stainless steel faceplate, and an IP66 weather rating. It runs from -4F to +158F (-20C to +70C) and tolerates 5 to 95 percent relative humidity non-condensing, so a gate, loading dock, or exterior man door is within its range.
2) What voltage does the KP-400 keypad need, and can I run it off my existing 12V access control power supply?
The KP-400 is auto sensing and accepts 12 or 24 VAC or VDC, so a standard 12VDC access power supply works with no jumper setting. Current draw is 10 mA at rest and 100 mA active on 12VDC, or 22 mA at rest and 120 mA active on 24VDC. Size the supply for the lock, not the keypad.
3) Will the KP-400 keypad relay switch a maglock or electric strike directly without an extra relay board?
Output 1 is a SPDT relay rated 5A at 24VDC, which is enough to switch a typical maglock or electric strike directly. Output 2 is a second SPDT relay but only rated 1A at 24VDC, so use it for a lighter load such as an auxiliary device, gate contact, or alarm input rather than a second lock.
4) How much wall depth do I need for the KP-400 keypad and its metal back box?
The keypad with back box measures 3-1/8 inches W x 4-1/2 inches L x 1-3/4 to 2-1/2 inches D. It is a surface mount unit, so the box sits proud of the wall and you are not cutting a deep pocket; you just need a flat surface and a wire penetration behind it.
5) Is the Alarm Controls KP-400 a standalone keypad or does it need an access control panel?
Self-contained. The KP-400 stores its own user codes and switches its own relays, so it does not report to a panel or head-end and needs no controller, software, or network drop. Wire power in, wire the lock to the relay, program the codes at the keypad and the door is done.
6) How many user codes does the Alarm Controls KP-400 hold?
Up to 100 users on output 1 and 10 users on output 2. That is enough for a single tenant suite, a small office, or a multi-family common door, but a property with hundreds of residents will outgrow it. Programming is done entirely from the keypad, so no software or laptop is needed to add or delete a code.
7) Does the KP-400 keypad support a request to exit device and a duress code?
Both. There is a dedicated REX input for tying in an exit button, motion sensor, or panic bar switch so the lock releases from the inside without a code, plus a duress output and a door prop open alarm. For a facility that monitors its openings, those are the two features that separate this from a basic standalone keypad.
8) Is the KP-400 vandal resistant enough for an unsupervised exterior entrance?
It is built for abuse: die-cast metal keys rather than a membrane or rubber pad, a 302 stainless faceplate held on with tamper-proof screws, and a built-in tamper switch that can be wired to an alarm if someone tries to open the housing. The keys are backlit with audible and visible feedback, which matters on a dark exterior door at night.
9) Can I leave a door unlocked during business hours with the KP-400 keypad?
Yes, it has a programmable passage mode that holds the output latched so the door stays open during business hours, then returns to code-required operation. It also has a false-code lockout mode that shuts the keypad down after repeated wrong entries, which discourages someone standing at the door trying combinations.
10) What finish does the KP-400 keypad faceplate come in?
One finish, satin stainless steel, on a 302 stainless faceplate over a black powder coated back box. If you are standardizing hardware across a building, it reads as brushed stainless and sits comfortably next to 630 satin stainless lever trim and push plates.
