A relay is an electrically operated switch and in environment detectors, low current switching signal relays are used to indicate a change in operating state from ON to OFF or OFF to ON. A signal relay can be Normally Open (NO) or Normally Closed (NC). When a change in state is monitored, from NC to NO or NO to NC, an action can be taken. An example is a Smoke Alarm sensing smoke and changing the state of a relay as an audible and LED alarm is signalled. The relay can be monitored remotely by an environment monitor.
Environment Detectors
A range of detectors that can be used in conjunction with an environmental monitoring system to provide alerts and alarms when there is a specific environmental condition including power loss, motion, smoke, fire, air flow and water leakage. The detectors provide a signal contact to the environment monitoring unit which then follows a pre-set routine in terms of response to the alarm condition.
