MOUNTING.
The Mosquito MK4 housing has a louvered front (see below). It is VERY important to note
when installing the Mosquito that the louvers project the sound down at a 45 degree angle.
This means that if you mount the Mosquito directly on to a wall, the sound will project down
at 45 degrees.
If the area to be targeted is further away than this 45 degree angle will cover, you MUST
use the mounting bracket (supplied) and either angle the unit upwards (to increase the
range) or downwards (to reduce the range).

SPEED OF EFFECT
The Mosquito has been known to work within 30 seconds of being activated, however,
sometimes it can take a week or two of regular use for the teens to stop causing the
problems and or hanging around at the location.
The speed at which the Mosquito will have the desired effect will depend on several factors
1. Volume setting
2. Frequency setting
3. Distance to target area
4. Ambient noise levels
The quieter the location and the closer to the target area you can install the unit, the faster
you will see results.

POWER CONNECTION
Most people purchase a 15v AC power supply with their Mosquito MK4. If you have not
ordered a power supply with your Mosquito, you can either obtain one from our website or
purchase one from your local electrical wholesaler. If purchasing from a wholesaler, you
must specify either a 15v AC or 24v DC power supply rated at 800mA.
Once you are ready to connect the power supply to the Mosquito MK4, locate the power
input terminals (top left of above image). There is no polarity issue to worry about, so it
does not matter which wire goes in which side. Just ensure you tighten the connections fully.
FUNCTION SELECTION
www.compoundsecurity.co.uk
First of all, you must decide which functions you wish to use. Choose these from the
Function list above.
The fuction selection switches (DIP switches) can be located on the red block at the middle
right hand side of the above picture.
The following picture shows ALL DIP switches set to the OFF position. If your DIP switches
are in a different position, please set ALL to the OFF position before proceeding.

DIPSWITCH #1.
This is ONLY used when a PIR (movement sensor) or Remote Control is being used to
activate the Mosquito. If you are NOT using a PIR or Remote to trigger the Mosquito, this
switch MUST be in the ‘OFF’ position.
If you are using a PIR to trigger the Mosquito, function chip #2 MUST be fitted. Setting this
DIP switch to the ‘ON’ setting will allow the Mosquito to run for 5 minutes each time the PIR
detects movement. If this DIP switch is set to ‘OFF’ the Mosquito will run for 1 minute each
time the PIR detects movement.
If you are using a Remote Control PRO., function chip #3 MUST be fitted, then this switch
MUST be set to the ‘ON’ position (see further details below).
DIPSWITCH #2.
www.compoundsecurity.co.uk
If this DIP switch is set to ‘ON’ the Mosquito will operate in ‘Low Frequency’ mode which is
audible to people of all ages. If this switch is set to ‘OFF’ it will operate in ‘High Frequency’
mode audible to younger people only.
DIPSWITCH #3.
If this DIP switch is set to ‘ON’ there will be an audible beep that everyone can hear once
every minute that the Mosquito is running. If the switch is set to ‘OFF’ there will be NO
audible beep.
DIPSWITCH #4 & #5.
To set the volume you require, follow the congifureations for switches 4 & 5 below.
94dB - Switch #4 ‘ON’ & switch #5 ‘ON’
96dB - Switch #4 ‘ON’ & switch #5 ‘OFF’
100dB - Switch #4 ‘OFF’ & switch #5 ‘ON’
104dB - Switch #4 ‘OFF’ & switch #5 ‘OFF’

TRIGGER CONNECTION (WITH FUNCTION CHIP #3 FITTED)
If you wish to use a Pro. Remote control to trigger the activation / deactivation of the
Mosquito, the remote must be connected to the ‘Trigger Input’ block located in the top right
corner of the first image above.
Connect the switching wires from the Pro. Remote to the ‘TRG -’ & ‘TRG +’ terminals. You
MUST then set DIP switch #1 to the ‘ON’ position.
Connect the power wires from the remote Pro to the ‘12v +’ & ‘12v -’ terminals located on
the left side of the ‘Trigger Block’.
TRIGGER CONNECTION (WITH FUNCTION CHIP #2 FITTED)
www.compoundsecurity.co.uk
If you wish to use a PIR to trigger the activation / deactivation of the Mosquito, the PIR must
be connected to the ‘Trigger Input’ block located in the top right corner of the first image
above.
Connect the switching wires from the PIR to the ‘TRG -’ & ‘TRG +’ terminals.
Connect the power wires from the PIR to the ‘12v +’ & ‘12v -’ terminals located on the left
side of the ‘Trigger Block’.
The length of the time the Mosquito runs for each time movement.
FUNCTION CHIPS
The Mosquito is supplied fitted with one of two types of function chips. These chips are
located adjacent to the red DIP switch block inside the unit. The chips control the duration
that the Mosquito will sound for when powered up.
RED/BLACK Chip - If your Mosquito has a RED/BLACK chip, the unit will sound for 20
minutes when powered up and then shut down automatically and wait to be re-triggered.
This chip is generally installed in units that will be deployed in residential areas to ensure
that the Mosquito is not left on for long periods of time for no real reason. This chip is also
required if the Mosquito is to be triggered by a motion sensor.
GREEN/BLACK Chip - If your Mosquito has a GREEN/BLACK chip installed, the unit will sound
continuously all the time that power is supplied to the unit. This chip is generally installed in
units that are either to be used on private land or remote locations away from residences, or
when the Mosquito is controlled by a timer.
