Cooper Fulleon ROLP Roshni Low Profile Red with Shallow Base Tone 3

Cooper Fulleon ROLP Roshni Low Profile Red with Shallow Base Tone 3

Cooper Fulleon ROLP Roshni Low Profile Red with Shallow Base Tone 3 -540501FULL-0389XThe 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.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 baseOperatingThe 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 pushpull 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.Key Features102dBA sound output32 tones user selectableTwo stage alarmAutomatic synchronisationIdeal for general signalling and Fire useFire approved and general signalling tone optionsAlert and alarm functionImproved tone clarity reducing confusion
