Entry Control Equipment (ECE) Components

TM 5-6350-275-10

e. Entry Control Equipment (ECE) Components (see Figure 1-9). 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 (IAIJ) 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) Key Pad (item No. 3). 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.

(4) Card Reader (Item No. 4). 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.

f. Audio Assessment Devices (AAD) Components (see Figure 1-10).

(1) Audio Switcher Control (Item No. 1). The audio switcher interfaces with the Primary Monitor Console

(PMC), Primary Monitor Console (PMC) audio module, and the 16 line audio switcher. It controls up to 51,2

communication channels.

(2) Audio Switcher, 16 Line (Item No. 2). The 16 line audio switcher is used to interface 16 Remote Area Data

Collectors (RADCs) to the Primary Monitor Console (PMC). Up to 32 switchers could be integrated into the system.

(3) Intercom Handset (Item No. 3). The handset, used in conjunction with the Remote Area Data Collector

(RADC) audio module, is a lift and talk intercom device. When the handset is lifted from the cradle, an alarm is sounded

at the operator station, alerting the operator to a communication request.

(4) Auxiliary Audio Console (Item No. 4). The auxiliary audio console is a remote transmitter/microphone.

(5) Audio Assessment Device (AAD) (Item No. 5). The Audio Assessment Device (AAD) is a microphone that

can be turned on by the ICIDS computer when a sensor detects the presence of an intruder. It interfaces with the Audio

Assessment Device (AAD) Printed Wiring Assembly (PWA) in the Remote Area Data Collector (RADC).

(6) Remote Area Data Collector (RADC) Audio Module (Item No. 6). The Remote Area Data Collector (RADC)

audio module amplifies the audio signal at the Remote Area Data Collector (RADC). It has a volume control knob.

Power is provided through a 120 vac power supply. Interface with other audio devices is through terminal strips.

(7) Primary Monitor Console (PMC) Audio Module (Item No. 7). The Primary Monitor Console (PMC) audio

module provides the intercom base station and amplifier. It has a volume control knob
