Latching alarms means that if the alarm activates and subsequently the gas condition returns to normal, the alarm will remain latched until the RESET button is pressed. Non-Latching alarms reset automatically.
A latching alarm is an indicator that is activated when the smoke detector detects an elevated amount of CO or smoke. The indicator will flash once every five seconds until the event has ended. This feature can be helpful when it is difficult to pinpoint the initiating unit. In such cases, the alarm may flash a second time before the event stops. It also helps to determine if the alarm has already stopped when the user presses the silence button.
The latching alarm is activated if the source of CO or smoke has reached the threshold levels. This means that the levels of these gases are still high, even though the air is relatively clear. However, the CO or smoke content has dropped below the threshold. This can be a problem if the source of the smoke is in a room that has a high concentration of CO or smoke.
The photoelectric detector works by sending a beam of light that is reflected by smoke particles. When a smoke particle hits this beam, the photoelectric detector picks up the light and sends an electronic signal to sound an alarm. In addition to smoke detectors, this type of alarm should be placed in every bedroom. The user’s manual for each smoke detector should contain important information about the device’s operation.
