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.

Tones Table
Note (a): Tones approved under the Construction Products Directive for Fire Alarm Applications, are shown in the column marked
EN54-3.
Note (b): EN54-3 measurements shown reflect minimum expected SPL readings at Maximum Volume at the Loudest Point around the
EN54-3 defined sounder axis.
Note (c): All other tone measurements reflect mean manufacturers data based on 'on axis' measurements, and are not verified by a
Notified body.
Note (d): Detailed EN54-3 polar SPL measurements are available in this Product Manual.
Note (e): All measurements taken at 20oC operating temperature.
Note (f): For SPL figures at 12V DC, take 6dB of the readings for 24V DC.
