o. Entry Control Equipment (ECE) Components (see Figure 1-19). The Entry Control Equipment (ECE) is used to

control personnel entry and exit to secure areas, and to alert security monitors to attempts at unauthorized entry.

(1) Intelligent Access Controller (IAC) (Item No. 1). The Intelligent Access Controller (IAC) is a Printed Wiring

Assembly (PWA) that provides inputs for door status, requests to exit, four auxiliary alarms, and tamper. Outputs are

provided for door strike (electric locks), alarm bell, alarm output, and auxiliary output. In the standalone mode, the

Intelligent Access Controller (IAC) can store up to 2000 access tag records.

(2) Intelligent Access Unit (IAU) (Item No. 2). The Intelligent Access Unit (IAU) is a key pad and card swipe

device that interfaces with the Intelligent Access Controller (IAC). It is configurable for Personnel Identification

Numbers (PINs) up to 10 digits. It also provides a Liquid Crystal Display (LCD) for messages and operational

instructions, such as WAIT, ERROR, ACCESS DENIED, ENTER PIN, etc.

(3) Card Reader (Item No. 3). The Card Reader interfaces with the Intelligent Access Controller (IAC) to grant or

deny access to a zone. The readers generally fall into two categories: (1) insert or card swipe, or (2) proximity. With

a proximity reader, actual insertion of a card is not required. When used alone, the Card Reader is the least secure of

the three devices.

(4) Key Pad (Item No. 4). The Key Pad is another type of remote terminal unit that interfaces with the STARGATE

Printed Wiring Assembly (PWA). The Key Pad is used to place a zone into the secure mode. It also has some

maintenance functions.
