v3.1

This range of external warning devices includes 3 models: 2 wired at Grade 2 & 3 and 1 wire-free at Grade 2 all are

Environmental class IV and can be installed in security systems in accordance with EN50131-1: 2006 + A1: 2009.

The wired models comply to EN50131-4: 2009, WD type Z; the wire-free model complies to EN50131-4:2009, WD type W.

These warning devices feature one piezo and one LED strobe for audible and visual indication of an alarm activation.

Each model includes the latest innovation in electronics and incorporates a lithium Ion battery for better reliability, each

of the wired versions incorporates a smart charging circuit to optimise the battery capability and battery life.

A number of other unique features are listed below.

deScrIptIon

FeatureS & optIonS

Back-light

Only available on the PLUS version.

It is possible to select either ON or ECO (default). In the ON position the back-light is permanently ON. In the ECO

position the inbuilt light sensor will automatically switch the back-light o during the day, thereby reducing power

consumption.

Test

Conrmation

Only available on the PLUS and WIRE-FREE versions.

This feature allows the user to be notied before entering the premises that the intruder alarm system has generated

a conrmed alarm due to 2 or more detectors being activated.

During an alarm activation if a negative (0v) signal is applied to the conrmed input at the same time as a signal is

applied to the siren input the siren tone will change to a rapid tone every few seconds. If a signal is applied to the

strobe input, the strobe ash rate will also change. If the signal is removed from the conrmed input, the tone/ash

rate will revert back to the standard tone/ash rate.

If the signal is removed from the siren/strobe inputs the sounder will stop sounding/ashing regardless of a signal

being applied to the conrmed input.

Only available on the PLUS and WIRE-FREE versions.

If a positive signal is applied to this input it will start the test routine. At the start of the test the fault output terminals

will go open circuit. During the test the siren will sound for 3 seconds, strobe will ash for 3 seconds and battery will

be tested to ensure that all are functioning correctly. At the end of a successful test the Senza will make a low level

sound and the fault output terminals will change to a closed circuit.

If a fault is detected, the fault output terminals will stay open circuit until the fault has been rectied.

Trigger Monitoring

Only available on the PLUS version and is mandatory for all grade 3 installations.

When selected, the device monitors the siren and strobe trigger wire’s integrity by means of monitoring resistors.

These resistors are connected to the opposite signal that is required to activate the siren or strobe i.e. negative siren

trigger signal (default), the monitoring resistor is connected between a positive and the trigger wire in the control

panel. In the event of the siren trigger wire being cut or removed, the fault output circuit will open. In the event of the

strobe trigger wire being cut or removed the strobe will start to ash. The fault output circuit will NOT be activated.

Note:- Fitting the resistor in the warning device does not comply with grade 3 requirements.

Engineer Hold-o

During the rst installation of the Senza this feature allows you to connect the on-board battery without the sounder

sounding, after hold-o voltage is applied the Senza will enter its normal mode. If Hold-o voltage is removed the

sounder will sound.

Fault

Only available on the PLUS and WIRE-FREE versions.

The 2 fault outputs are normally closed and will switch to an open circuit if a fault occurs with the sounder, strobe, and

battery. If trigger wire monitoring has been selected the fault output will also open circuit if a fault is detected. It also

acts as conrmation that the test procedure has been started by going open circuit and on a successful completion of

the test procedure the outputs will go closed circuit.

Volume

Each model will allow you to select the dB(A) level required to comply with the country/regional requirements it is

possible to reduce the sound output from 105dB(A) (default) to maximum sound output of 85dB(A)

locatIon oF partS

Tamper Return

SAB/SCB

Trigger Signal

Siren Cut-o timer

Only available on the PLUS versions.

In SAB mode (default) the power required to produce the sound is drawn from the security systems control panel. In

SCB mode the power required to produce the sound is drawn from the on-board lithium Ion battery.

It is possible to select 1 of 3 optional times depending on the model being used

The PLUS version and the WIRE-FREE version have either 15minutes (default) 3 minutes or intermittent (50sec ON,

50sec OFF, 50sec ON, 50sec OFF, 50sec ON then stops (times are approximate).

The STANDARD model only has 15minutes (default) or intermittent.

Each model allows you to select the triggering method used to activate the siren and strobe, either Negative 0v

applied (default) or positive +ve applied, depending on the output of the control panel you are using.

Only available on the PLUS and WIRE-FREE versions.

Allows you to select either a Negative signal (default) or a positive signal for the Tamper Return signal to match the

requirements of the control panel being used.

Strobe Saver

After 1 hour of continuous activation the strobe ash rate will be reduced from 1Hz to 0.25Hz

WIRE-FREE version Only

During the installation of the Wire-free version it is possible to check that the best location is selected for the warning

device. Whilst in engineer mode the Green LED will ash to indicate that the warning device is communicating

with the control panel module, if the Green LED stops ashing this indicates that it has lost communication with

the control panel module. Relocate the warning device until the Green LED starts to ash, this indicates that

communication have been re-established.

mountIng InStructIonS

Identify a suitable mounting location for the warning device on a at wall. If you are installing the

Wirefree version, you can use the built-in coms feature to locate the best location and ensure the there is

communication between the warning device and the control panel module.

It should not be possible to reach the device without the aid of access equipment, where practical it

should be sited under the eaves to give additional protection.

Mark the xing points on the surface of the selected location using the drill template on the back of the

box. Drill 3 holes using a 5.5mm masonry drill 41mm deep for the enclosed wall plugs, insert the wall

plugs into the holes, t the top centre screw, enclosed, leaving it protruding by 25mm.

Feed the cable through the cable entry point on the

senza

and carefully slot the top xing point of the

senza

over the previously installed screw, rotate the 2 x bottom xing points, if necessary, to allow the

holes to line up and x in-place using the enclosed screws.

Please note in order for the tamper protection to function correctly one of the mounting screws is

required to be tted in the removal from wall mechanism as shown below. Do not over-tighten this

screw. If forced removal is attempted this will cause irreversible damage and may need replacing.

Use the

template on

back of the Box

mountIng InStructIonS

control panel model (cpm)

When identifying a suitable mounting location for the CPM, the following points should be noted:

• Do not mount next to an AC source

• Mount away from wireless interference sources (computers, cordless phones, wireless routers, etc.)

• Large metal objects (a distance of 1m is recommended)

Temporarily place the unit in the selected location (do not hold) ensuring that the CPM is vertical,

using the built-in coms feature in the warning device, ensure that there is communication between the

warning device and the CPM see page 12, if not move the location of the CPM and repeat the process.

Mount the CPM in the selected location, connect the CPM to the control panel as shown on page 12.

Please refer to the DIP switch setting on page 7 to setup the device for the conguration you require.

To activate the siren apply an appropriate signal (depending on selection made via the DIP switch) to the

SIREN terminal (3). To deactivate the siren remove the applied signal.

To activate the strobe apply an appropriate signal (depending on selection made via the DIP switch) to

the STROBE terminal (4). To deactivate the strobe remove the applied signal.

During an activation of the Siren and/or Strobe, if a negative signal is applied to the Conrmed Terminal

(6) it will change the Siren tone and/or the Strobe ash rate. Removal of the signal will result in the Siren

tone and/or the Strobe ash rate returning to it normal tone/rate.

If the device’s tamper protection is activated by opening the cover or by forcibly removing the warning

device from the wall, the signal (depending on the selection made via DIP switch) will be removed from

the Tamper Return terminal (5). Closing the cover will result in the signal being restored.

Note: The Senza is designed not to sound when the tamper switch is opened to allow for the installation/

service engineer to access the unit without genterating a sound, however this will depend on the

condition/settings of the control panel it is connected to e.g if the panel is in a set condition the sounder

may sound.

If a positive signal is applied to the Test input (7) it will start the test routine.

If the rechargeable battery is disconnected from the device or is not capable of supplying

power to the device, then the Fault output circuit will open.

The loss of the remote power source to the device will activate the siren for the pre selected time via DIP

switches 7 & 8 on the

Plus

or DIP switch 3 on the

standard.

the

Green

(tamper) and

red

Green

LED stops

ashing this indicates that the tamper protection for the cover and/or the removal from wall is open. If

the

red

LED stops ashing this indicates that there is no voltage on the Hold-o terminals.

The Red battery LED is illuminated when the battery is healthy. If the LED is extinguished this indicates

that the battery is disconnected or faulty.

Wired models

Please refer to the DIP switch setting on page 7 to setup the device for the conguration you required.

To activate the siren apply an appropriate signal (depending on selection made via the DIP switch) to the

SIREN terminal. To deactivate the siren remove the applied signal.

To activate the strobe apply an appropriate signal (depending on selection made via the DIP switch) to

the STROBE terminal. To deactivate the strobe remove the applied signal.

During an activation of the siren and/or strobe, if a negative signal is applied to the Conrmed Terminal

it will change the siren tone and or the strobe ash rate. Removal of the signal will result in the siren tone

and/or the strobe ash rate returning to it normal tone/rate.

If the device’s tamper protection is activated by opening the cover or by forcibly removing the warning

device from the wall, the signal (depending on the selection made via DIP switch on the CPM) will be

removed from the Tamper Return terminal and the sounder will sound. Closing the cover will result in the

signal being restored and the sounder stopping.

If a positive signal is applied to the Test input it will start the test routine. Failure of the test routine will

result in the fault output staying open.

The battery is monitored every 24hrs and this test checks the condition of the battery by applying a load

to the battery. If the battery fails this test the fault output will open circuit.
