EAP01 - Product Manual

1 Description

The EAP01 Emergency Announcement Point is housed in an IP65 vandal resistant, lockable wall-mounting

box. It is designed to work with the whole range of ASL Voice Alarm and Public Address systems, and is

normally used for making All-Call emergency announcements to entire facilities. The unit features indicators

for ‘Busy’, ‘Speak Now’, and ‘System Fault’, together with a ‘Status’ indicator.

The EAP01 will operate in an All-Call mode even in the event of processor failure within the Router

, as

required by BS5839 Pt.8. The unit should be connected to Router’s inputs 1 or 2, which operate in the All-

Call failsafe override mode in the event of processor failure.

Hardwired connections to the Emergency Announcement Point interface all LEDs and switches to the

Router, while microphone audio is provided as a balanced 0 dBu (nominal) analogue signal. The EAP01

features a built-in signal limiter to accommodate varying operator technique. The microphone’s processor is

responsible for generating an outgoing 20 Hz surveillance tone which is used to monitor the audio

connection to the Router, while microphone capsule monitoring is performed by injection and monitoring of a

signal such that either open or short circuit of the capsule or associated wiring will indicate a fault.

Hardwired connections are provided for the PTT switch, and Speak Now and System Fault LEDs. The

cabling to the PTT switch and Speak Now LEDs is continuously monitored by the Router for open and short

circuits.

Field connections are provided on the inside rear panel of the back box by DIN rail mounted terminals.

The Router can be either a rack mounted or a wall mounted ASL Voice Alarm and Public Address system:

• Rack mounted system: VAR4, VAR12, VAR20, VAR8, or VAR8-ACU

• Wall mounted system: DAU (Distributed Amplifier Unit), or ACU (Audio Control Unit)

Issue: 02 complete, approved
