Today’s Standalone Keypads
Today’s standalone keypads have many more features available including managing hundreds of users, operating on a time date schedule and providing audit trail. They can provide complete access control functionality, which can include monitoring the door’s position, trigger a propped or forced door alert or have an alarm shunt. Some standalone keypads serve a dual function as they can also be networked. A keypad can be used to control just about every type of electrified lock hardware or trim.
There are specialty keypads for interior or exterior, vandal prone applications, harsh conditions and backlit keys. Some keypads are surface mounted, flush mount and mullion mount.
A standalone keypad can be a single component, for example Linear’s IEI brand 212i, a flush-mount telephone style keypad with three LEDs that is designed for lighter volume interior applications. The 212i has non-volatile EPROM memory and up to 120 one- to six-digit user codes. Audit trail is available as an option. This keypad is designed to install into a standard single gang electrical box. Add an electric strike or electrified lock and a power supply and you have a single door access control system.
A disadvantage of standalone keypads is that, depending upon the installation and wiring method, damaging the keypad can provide access to the wiring in order to gain unauthorized access.
Two-component products such as the Securitron DK-26 consist of a narrow stile keypad and a Central Processing Unit (CPU) logic board connected by a 16-foot cable. This configuration permits the CPU to be mounted away from the keypad for higher level of security. The DK-26 stainless steel keypad is weatherproof with true 10-button operation and up to 119 two- to seven-digit user codes.
For outdoor applications where a significant number of user codes are required, the SDC 925 Series Outdoor Digital Keypad has up to 480 one- to six-digit user codes that are programmed at the keypad. The keypad is designed for outdoor applications having die-cast metal keys and a heavy duty aluminum keyed lock enclosure. The SDC 925 offers audible and tactile feedback for programming and operation in addition to dual color status indicators. Two Form C relay outputs offer programmable activation and activation times. In addition, there are two open collector outputs. The Outdoor Digital Keypad offers Request-to-Exit input and time anti-passback. A door/gate sense input provides control of auto relock and door ajar.
Some keypads have dual credential capabilities. For example, the Sargent 4293 Standalone Prox Reader and Keypad offers all of the expanded capabilities of the Sargent Profile Series v.G1.5 lock hardware contained in a compact hard-wired reader designed for interior applications. The Sargent 4293 is a keypad with detachable proximity reader that provides standard access control functionality with its two Form C relays. The two inputs provide request to exit and door position. The proximity reader can be removed from the keypad and mounted up to a maximum of 10 feet away. The keypad and proximity reader can be mounted on opposite sides of a door, restricting access and egress using different credentials.
This dual-credential proximity reader and keypad offers a higher level of security when both are required to gain access. The UL 294 Listed Sargent 4293 can be used for standalone access control, or used as a reader as part of HID 125 KHz Weigand formats up to 40 bit. Up to 2,000 User Codes can be programmed and there is a 2,000-event audit trail.
The Sargent 4293 proximity keypad can be programmed at the keypad as well as from a personal computer using SofLink Plus Version 4.0 or higher software. The 4293 is equipped with infrared (IR) communications that allow the unit to be programmed with SofLink PDP software. No separate controller is needed for the 4293. This keypad includes HID proximity technology, a keypad, and the controller.
