System Sensor SSV120-10 03/02 Primary applications include notification appliance

Primary applications include notification appliance (bell) circuit (NAC) expansion (to support ADA requirements and NAC synchronization) or auxiliary power to support 24 volt system accessories

The detector is part of a two component system: the duct detector housing and the duct detector head

which are conventional smoke detectors that can transmit a maintenance trouble signal to the FACP indicating the need for cleaning and a supervisory ‘freeze’ signal when the ambient temperature falls below the detector rating of approximately 45 °F

especially to notify the hearing impaired

The wall-mount low-frequency sounder and low-frequency sounder strobes were designed to address the NFPA 72 sleeping space requirements that require a low-frequency notification appliance that operates within the frequency range of 520 Hz +/- 10% and is of a square wave tone
