A door is only as disciplined as the keypad that guards it.
The weakest point in a small alarm system is rarely the sensor. It is the routine that arms and disarms it. A keypad that requires a precise sequence in the dark, on the way out, is a keypad that gets left disarmed. This unit is a 433 MHz wireless touch keypad that works with EV1527 encoded alarm hosts, with a backlit touch surface, a doorbell button, and three ways to open: password, RFID card, or card plus password together. Each keypad ships with two RFID cards, so a second person can carry their own credential instead of sharing a code.
The device supports up to two thousand standard users, which places it well beyond domestic use. That capacity makes it relevant to small hotels, offices, and serviced apartments where staff and guests change regularly and re-issuing cards is preferable to circulating a password. An anti-disassembly alarm reports tampering at the keypad itself, and the CE and RoHS certification covers the electrical safety and materials requirements a commercial installation needs.

Who It Is For
The installation that suits this keypad is a door where several people need access and the credentials need to be revocable. Small hotels and serviced apartments issue an RFID card to each guest, then retire it at checkout without changing a building wide code. Offices use the password plus card mode on the main entrance so that a lost card alone is not sufficient to gain entry. Factories and workshops mount it on a staff or storeroom door where hands are often gloved, since the touch surface reads a card without a keypress. Home users get the doorbell button and night visibility as a bonus.
Commissioning a keypad takes a few minutes once the host is in pairing mode. Cards are enrolled one at a time, so it is worth labelling each card with a name or unit number as it goes in, otherwise a checkout without a matching record becomes guesswork. Backing up the enrolled list in the host is the difference between issuing a new card and reconfiguring the door.
Frequently Asked Questions
Q: Does this keypad work with my alarm system?
It communicates on 433 MHz using the EV1527 encoding standard, which is widely used by alarm hosts. Confirm that your host supports 433 MHz EV1527 devices before ordering.
Q: How many RFID cards are included?
Two cards are supplied with each keypad. The keypad supports up to 2000 users, so additional cards can be added where the host allows enrolment.
Q: Can it be used without an alarm host?
It is designed to pair with a 433 MHz alarm host for arming and disarming. Used on its own it can still report code entries, but the full access control behaviour depends on the host.
Q: Is it suitable for outdoor installation?
It is intended for sheltered doorways in homes, hotels, offices and apartments. Avoid direct rain exposure and prolonged standing water on the touch surface.
Q: What happens if someone forces the keypad off the wall?
The anti-disassembly alarm is designed to trigger when the unit is removed from its mounting, so tampering is reported rather than silent.
Q: How do I add a new RFID card?
Put the alarm host into pairing mode, then present the card to the keypad. Repeat for each card, and record which credential belongs to which user so it can be removed cleanly later.
Q: Can the password be changed?
Yes. Access codes are configured through the alarm host rather than the keypad itself, so code management follows your existing host workflow.
