Introduction
The ROLP sounder is an affordable wall mounting sounder which is suitable for audible
signalling within open areas or corridors and passages. The sounder is designed for use within
fire alarm systems, intruder alarm systems and industrial signalling systems. It is able to
produce 32 tones via the coding switch on the rear of the unit (see installation sheet/tones table
for more detail). A second tone can be activated remotely by using the third terminal. A volume
control adjustment is also provided.
Connection is via a screw terminal connector block for ease of termination of cables. Each
connection has a terminal for looping in and out. The sounder is fixed to a location using a
bespoke shallow clip on lockable base.
General Functional Description
The device is normally in an off state, with no voltage applied to the power terminals. In this
state, the unit has no power and so does not produce any sound.
When the unit is required to produce sound, a voltage between 9 and 15 D.C. or 18-28V DC is
applied to the appropriate power terminals. This provides power to the circuit via a polarity
protection diode, & an RC network which provides supply smoothing and noise immunity
protection. Further protection is also provided against voltage spikes on the supply. At the heart
of the sounder is a microprocessor which derives its power from a linear voltage regulator
circuit. Clock timing and sounder synchronisation is provided via the oscillator clock drive crystal
& associated capacitor network.
The tone generated by the microprocessor depends on the tone switch settings. After power up
and initialisation, the firmware code starts executing the relevant pulse output from the
microprocessor. This drives a transistor circuit which in turn drives a push/pull amplifier
arrangement which drives the loudspeaker circuit.
Some adjustment of the output sound level can be achieved using the volume control
adjustment (if provided), which reduces the current drive to the transducer.
If the user wishes to select a second tone remotely, the additional connection on the terminal
block is taken to ground (i.e. -ve supply to “2nd TONE -” terminal). This sets the microprocessor
firmware to generate a different tone.

Installation Guidance & Advise
General Safety Advice
•Do not work on live circuits
•Follow local wiring regulations where relevant
•Ensure that the base is secured to the mounting surface using the most
appropriate fixings. Plasterboard walls will require special wall plugs.
Maintaining IP (Ingress Protection) ratings – Good Practice
•Use suitable cable glands to maintain the designed IP rating. The stated product
rating will ONLY be achieved if the product is installed correctly. A selection of
suitable glands is available from all good electrical wholesalers. Always follow the
cable gland instructions.
•Product orientation is important. If it is desired to achieve a high weatherproof
rating, all cables should be brought in and out from the underside of the device.
Avoid cable entry from the top side, as water could drain in over time.
•Ensuring that all base and mounting screws are secure.

Power Supplies / Control Panels
•Use a power supply or control panel capable of providing a steady state current of
at least 1.2 x the rated operating current of each device.
•Use a power supply or control panel capable of providing a surge current of at
least 1.5 x the surge current of each device for at least 10mS.
•A suitable slow-blow fuse must be fitted to the output stage of all power supplies,
to help prevent fuse blowing during power up.
•Where a large number of units are to be wired, it is recommended to use multiple
power supplies on separate spurs or loops to avoid the huge voltage drops that
would otherwise be encountered. See diagram below: -

Wiring
It is essential to know the series resistance of the cable before making a choice
here. It is recommended that the thickest wire possible is used. This ensures that the
series resistance is minimised and thus the length of the wiring that can be used is
maximised. All the measurements and calculations shown on the following pages are for
a maximum solid core wire cross sectional area (CSA) of 2.5mm2. If using a different
cable type, CSA or a material other than copper is used the value of the series resistance
of the cable (Rs) will need to be adjusted in the formula below.
Please note that that all calculations here are for spurs only. It is risky to do
calculations on loops, since if one side of a loop were to fail, the maximum equivalent
series resistance could double. This may result in possible system start up problems or
poor performance issue due to excessive voltage drops.

Recommendations & Assumptions:
oCopper wire with core cross sectional area (CSA) of 2.5mm2is assumed to be used
oRS(Maximum series resistance of copper wire) = 0.7ohm per 100meters (typical)
oPower supplies must be capable of delivering surge currents of 1.5x surge current of
each device for at least 10mS
oAll sounders are assumed to be wired to the end of a spur (i.e. worst case scenario)
oWhere the length of cable or number of sounders used becomes an issue, it is
recommended to group units together and use a separate power supply & wiring spur
for each group
Formulae:
oCable Resistance: Rc= Vdrop / Is(where Vdrop = 10 x 10%)
= 1V / Is
= 1V / 0.04 = 25 ohm (a)
oCable Length: L = Rc/ [Rs/(100 x2)] (assumes feed / return (+/-) wires are same length & diameter)
= Rc/ 0.0035 ohm
= 25 ohm / 0.0035 ohm = 7142 meters (b)

Maintenance Advice
•The product is of a low maintenance design. However, systems should be tested
on a regular basis after installation. This is vital where products are used in life
safety systems. Please refer to current & relevant maintenance practices.
•If the product is installed in a harsh environment, check seals and housing
condition for any obvious signs of ware and tear or damage on a periodic basis.
•Cleaning of the product housing should be carried out using non-abrasive and
non-corrosive substances. A lightly moistened soft cloth is usually sufficient.
