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.
