Introduction
The AMPAC Warning Signs provide clear, visual and
audible indication of an alarm event and are designed
for use with fire detection and alarm systems which may
incorporate agent release capability. The display may
also be customised as required to cater for a variety of
applications.
The Warning Signs are available in two standard
formats, the 4210-0110 for semi-flush or surface mount
indoor applications while the 4210-0120 affords IP65
weatherproof capability for outdoor applications.
The Warning Signs incorporate a split level design that
enables two text messages to be independently
controlled through the application of input voltages. The
two levels may be activated by either a voltage
reversing DC input or through application of a common
positive and two switched negative DC inputs.
Option switches located inside the unit enable the
commissioning engineer to further configure the
Warning Sign for continuous or flashing Red or Yellow
LEDs, enable an integral buzzer in continuous or
pulsing mode of operation, to enable a mute facility to
silence the buzzer and or optional external sounder. A
facility to synchronise the flashing between multiple
signs is also provided.
Illuminated using the latest in high efficiency, high
intensity LEDs to greatly reduce power consumption
and increase reliability ensures that the brightness is
maintained even when running on depleted stand-by
batteries.
Note: A maximum of 6 AMPAC Warning Signs can
be connected to the output of the Agent Release
Board.
Installation (4210-0110 enclosure)
Open the outer door using the plastic key device
provided. Using the back box as a template, mark the
position of the four fixings in the required position on the
mounting surface. For semi-flush fixing applications, cut
a hole in the mounting surface to the dimensions shown
below ensuring adequate depth is provided for the unit
to be recessed.
Before fixing the unit decide which entry points are to
be used for the in-coming cables. The back box has 7
20mm knockouts in the top and bottom which can be
easily removed by sharply tapping them with a blunt
instrument and hammer.
Top entry is recommended on this product however,
back entry can be achieved by drilling additional holes
in the back box to suite. Fix the back box to the
mounting surface using 4 appropriate sized bolts or
screws and install the acrylic text fascia plate using the
6 screws provided.
Installation (4210-0120 - weatherproof enclosure)
The weatherproof enclosure should be surface mounted
using appropriate fixings and sealing washers.
o
Using the 6x outer screws, remove the clear
Perspex lid.
o
Using the 4x black dome nuts, remove the text
legend fascia plate bezel.
o
Remove the internal printed circuit board using the
2x screws located in the centre of the PCB.
o
Drill 4x 4mm fixing holes in the rear of the back box
near each corner and fix the back box to the wall
using appropriate fixing screws or bolts. Ensure
that a watertight seal is maintained around the
fixing holes.
o
Re-instate the printed circuit board and fit the
acrylic text legend to the fascia plate bezel using
the 6x M4 nuts provided.
o
It is recommended that the fascia plate bezel
complete with acrylic text legend should be re-
instated following initial testing of the system.
Cabling
The maximum size of cable that the terminals will
accommodate is 2.5mm². The interconnecting external
cables should be connected to the back box using
suitable cable glands. On the 4210-0120 back box,
waterproof lock-tight glands should be used to ensure a
weatherproof seal is maintained. Ensure that cable tails
of sufficient length are maintained to reach the
terminals without cutting across the front surface of the
internal printed circuit board as this will impair the
illumination of the sign.
The Warning Sign can be configured to illuminate in two
ways. For voltage reversal, 2 wire applications and for
use with the AMPAC Agent Release module, refer
figure 1. For common positive, switched negative 3 wire
applications, refer figure 2.
Configuration Switches
The Warning Sign can be configured to operate in a
variety of ways using DIL switches located on the
printed circuit board. Table 1 outlines the functionality of
the on-board switches located at SW2, switches 1 - 8.
SW1 controls the colour of the LEDs during the
operation of the sign, Red or Yellow and should be set
to suit the application of the Warning Sign.
