INSTALLATION GUIDE

EXTERNAL SOUND UNIT - INTRODUCTION

Your AZ-TECH External Sounder with on-board Strobe unit is designed to form an integral part
of any Residential or Commercial Security Alarm System. The Unit has certain selectable
features with which we recommend that you familiarise yourself prior to commencing installation.

Battery ON / OFF:

Your Sounder has its own on-board NiMH back-up battery. This enables it to operate
independently of the main control panel should disconnection occur (ie. during an attempt to
disable the unit).

When the battery jumper is in the OFF position the battery is isolated, the Sounder will not
operate unless it is connected to the Control Panel and a ‘hold-off’ voltage is present.

When the battery jumper is in the ON position the battery is connected to the Bell box circuit
allowing stand alone, SAB / SCB operation and trickle charge of the battery when a ‘hold off’
voltage is applied.

SAB / SCB:

SAB: (Self activating Bell unit). The standard sounder operating mode, providing maximum

sounder volume. Upon sounder activation, current is drawn from the control panel, unless ‘hold
off‘ voltage is removed (ie. as a result of power disconnection from the control panel during an
attempt to disable the unit).

SCB: (Self contained Bell unit). In this mode, upon sounder activation, current is drawn only from
the on-board NiMH rechargeable battery, not from the Control Panel. This is ideal when using
secondary sounders so that you do not overload the Control Panel or power supply current load
capacity. Sounder volume is reduced in this mode.

Timer Select: 15 Min / 9 Min / 5 Sec

The sounder cut-off time is selectable . 15 or 9 minutes ‘cut-off’ and 5 second test mode are
provided. The test mode is utilised upon initial set-up in order to minimise sounder operating
time, thus enabling the engineer to work on the unit with minimal noise disturbance.

MOUNTING YOUR AZ-TECH SOUND UNIT

Consider the following criteria when mounting the unit:-

 Mount high enough to deter potential tampering and to afford some shelter.

(preferably under the eaves).

 Mount in a prominent location so as to maximise the deterrent effect.

 Ensure that you have adequate cable access to your chosen location.

 Try to select a flat even mounting surface to ensure the rear micro-switch tamper

mechanism locates correctly against the wall surface.

(Note: Where mounting surfaces are uneven you may need to bend the micro-switch blade
to effect a good solid contact against the wall surface thus ensuring reliable operation of
the front / rear tamper mechanism).

 There are five screw mounting holes on the units backplate to ensure secure fixing even

where the mounting surface may be uneven.

N.B When mounting the unit upon a brick wall, BS4737 specifies that a minimum of 3 x No.10
size steel screws be used. They must penetrate the brick itself by at least 40mm using
appropriate wall plugs.

Drill all holes required for mounting the unit, using the positioning template provided on the rear
of the cardboard outer box, and insert wall plugs.

Affix the Sound Unit backplate to the exterior wall ensuring that your connecting cable has been
inserted through the appropriate cable entry hole.

INSTALLATION & WIRING OF YOUR AZ-TECH SOUND UNIT

Connecting the Sound Unit to the Alarm Control Panel:

Utilising the terminal connectors to the left side of your Sounder’s PCB, wire in as follows:-

TAMPER RETURN : Negative tamper return
BELL TRIGGER : Negative applied output to activate the Sounder
SUPPLY (12V+) : Permanent positive supply
SUPPLY(OV-) : Permanent negative supply
STROBE (-) : Negative applied output to activate Strobe

We recommend you wire into the Sound Unit first and the Control Panel second.

NB: If you are wiring in a basic model AZ-120 unit ( ie. without SAB function

or anti-tamper) then you do not need to connect to the TAMPER RETURN.
However you do need to place a link between the M/SWTCH Terminals to
bypass this function. ( See Fig.1)

Your AZ-TECH Sounder is compatible with most Intruder Alarm Control Panels. Please see the
table at the rear of this booklet that illustrates connection to many of the most popular Control
Panels available. If your Alarm panel is not listed in our table please refer to your Alarm Panel
Installation manual for appropriate wiring instructions.
