5.5 EIS Operation
5.5.1 General
The purpose of the Emergency Intercom System is to provide a dedicated communications system
between the Main Fire Warden (usually situated in the fire control room) and the Floor Wardens,
situated at the Warden Intercom Points (WIP), which are normally located on each floor of a building
near the egress points.
The EIS is used by fire wardens and other suitably trained personnel to assist in the evacuation,
relocation or direction of personnel in an emergency situation.
To achieve the above, the EIS provides the following communications:
• Establish a call from the EICIE handset to a handset at WIP
• Establish a call from a WIP handset to an EICIE handset
•
Support a multi-party conference (up to 5 WIP handsets) in a full duplex call
• Support a half-duplex All-Call broadcast – to all WIP handsets
5.5.2 Establish a call from the EICIE handset to a WIP handset
To establish a call from the EICIE handset to a WIP handset, the following procedure is followed:
1 Remove the handset from the cradle at the EICIE (off hook)
2 Confidence tone will be broadcast in the ear piece, to indicate the EICIE has
recognised the handset going off hook.
3 Select the WIP handset to call by activating the appropriate Call control (refer to
section 5.1.13)
4 The call indicator flashes and a ring tone replaces the confidence tone in the ear
piece.
The buzzer on the selected WIP handset is pulsing (matching the frequency of the
ring tone).
5 To answer the call, the WIP handset is taken off hook, and the call indicator goes
steady.
A full duplex call between the handset at the EICIE and the handset located at the
WIP has been established.
6 To terminate the call at the EICIE, place the handset at the EICIE on hook. If the
handset at the WIP remains off hook, then the EICIE treats this as a call from a
WIP handset, and the ring tone is broadcast in the ear piece of WIP handset and
the corresponding Call indicator flashes at the EICIE. Refer to section 5.5.3, step
3.
7 To terminate the call at the WIP handset, place the WIP handset into the cradle
(on hook).
The Call indicator is extinguished at the EICIE.
5.5.3 Establish a call from the WIP handset to the EICIE handset
To establish a call from a WIP handset to the EICIE handset, the following procedure is followed:
1 Remove the WIP handset from the cradle (off hook) at the WIP.
