The present invention provides a low battery trouble signal delay circuit for a smoke detector configured for periodically measuring environmental conditions and for producing a fire alarm signal when smoke is detected in the environment. The trouble signal delay circuit has a battery, a comparator ...
If an alarm starts giving a low battery chirp, the battery will need to be replaced regardless of what voltage you get on the battery/batteries. For AA battery detectors, what voltage causes a low battery chirp? The low battery chirp will start when the batteries' charge drops below 2.6-...
These op amps provide a cost-effective solution for space-constrained applications such as smoke detectors, wearable electronics, and small appliances where low-voltage operation and high capacitive-load drive are required. The capacitive-load drive of the...
