Ampac EvacUElite Loop Warden Installation Manual

EvacUElite Loop Warden Handset
Installation guide

1. Description

The Loop Warden Handset (Item no ASS63LWIPS)
connects to the 6350-LILC Card which is fitted within
the EICIE panel.
The cabling to the Warden Handsets originates from the
LILC and loops through each Warden Handset and
returns to the LILC to create a redundant loop circuit (see
page 4). Cable connections between the LILC and each
Loop Warden Handset are polarity sensitive.
Each LILC supports 2 loop circuits, and each loop can
connect up to 20 Loop Warden Handsets. A maximum
of 40 Warden Handsets can therefore connect to each
LILC.
The EICIE system can be expanded further by adding
more LILCs and GUI Control Cards which provide the
total number of zone controls required.
Each Loop Warden Handset is configured as an address
number (between 1-20) via the dipswitch setting inside
the Warden Handset on the PCB.
Each Loop Warden Handset address needs to be
assigned to an EIS Zone number between 1 to 1024
within the configuration file. Descriptors can be added to
detail their location.
Each zone is provided control buttons 'Call & Clear' and
assigned into the EIS keypad layout in the system
configuration file
Each Loop Warden Handset can interconnect with an
EAID via the dedicated system input (White Emergency
MCP) input terminals marked +- EAID.
If the Warden Handset ring tone is deemed insufficient
an external WIP Remote Buzzer Plate (Item No 209-
0028) can be connected onto the terminals marked +-
BUZZ. This is typically used when the Warden Handset
is located inside an enclosure, panel or behind a door.
The loop circuits require (2 core UTP) Unshielded
Twisted Pair field cabling wired in a loop configuration
connecting a maximum of 20 Loop Warden Handsets
over a maximum loop length of 1km. The distance
between any two Warden Handsets shall not exceed
500m.
The cable size recommended is 1.5mm
twisted pair.
Each Warden Handset should be fixed in an upright
vertical position when fixed on a wall, so the handset sits
firmly on the cradle
Suggested Fixing Height: between 1.1m – 1.3m from
floor level
Suggested Fixing Screw Size: Metal Roundhead 8g x
30mm
Fixing Centers on the Warden Handset are 188mm
apart vertically.
Two LED indicators are located on the PCB inside the
Warden Handset between the Buzzer and EAID
terminals.
The LEDs cannot be seen once the Warden Handset
cover is fixed on. The two LEDs provide the person
commissioning visual indications which help outline the
condition of the Warden Handset.
In normal operation when wired as a loop circuit the LED
status should be as follows:
•
•
•
In the event of short circuit, the LED on the affected side
of the circuit will turn off.
Short Circuit Isolator - Operating Description:
When a short circuit event occurs the loop controller
goes into a current limiting condition then disconnects
the line voltage after a short time. The controller will then
re-power the line. The loop device shall then power up
and reset the isolator to the open condition to protect
the rest of the circuit. The circuit will attempt to self-heal
until normal circuit conditions resume.
The ASS63LWIPs isolator is a low side isolator. It works
by disconnecting the low side connection between ports
when necessary conditions are not met and will only
reconnect both sides when the necessary conditions are
met. Connection of the isolator is a staged process.
Requirements for connection of the isolator are:

Both LEDs will illuminate ON steady. The
steady LED indicates the port input voltage 48
V DC and communications protocol from the
LILC is received.
If comms from the LILC becomes lost the
steady LED changes state and begins to flash.
The incoming primary line voltage to each
Warden Handset is typically 48 V DC under
normal circumstances (via the loop circuit) for
the Warden Handsets to operate within
specification.
The input port and output port voltages must
be above V connect min (24-28 V DC) The
output port voltage is obtained by a small test
current being placed on the output port.
One port must have communications up as
dictated by the protocol requirements. If neither
port has a valid communications connection,
then the isolator will not reconnect.
