A large, supervised terminal block (patent pending) featuring captured SEMS screws simplifies installation. SmartCheck™ self-diagnostics allow you to check the detector’s sensitivity range by simply looking at the unit. Every ten seconds diagnostic circuitry monitors chamber sensitivity, checking to see if the detector is within its UL specification range. If it is, the LED flashes every ten seconds. If not, the LED stops flashing – a clear sign the detector needs cleaning or servicing. So, to see if a 100 series is within specification range, just look at it. This meets NFPA 72 requirements for sensitivity testing. For sensitivity readout, use MOD 400 accessory and voltmeter. Heat Detection. Integrated thermal models provide restorable, 135-degree fixed-temperature heat detection. Isolated thermal models feature a fixed-temperature heat sensor that is isolated from the smoke sensor, providing a self-resetting, local audible smoke alarm. In these models only the isolated heat sensor will signal an alarm to the panel. The isolated thermal products are designed for applications where local annunciation, not total facility evacuation is desired. Sounder Models. A built-in piezoelectric horn (patent pending) in the 100 series sounder models produces the NFPA 72-required, 85dBA temporal tone pattern when the individual detector alarms or when the supply voltage polarity is reversed. continued Standard Application Specifications Operating Voltage 12/24 VDC (nominal), 8.5 min. to 35 max.
