Afriso WATCHDOG-LINE alarm units

Alarm unit in a wall mounting housing with audible and visual alarms. GM features an alarm threshold and is equipped with a relay contact. If the threshold value is exceeded, the unit generates an alarm signal. The red LED lights up, the audible alarm goes off and the alarm relay switches. The audible alarm can be muted with the Acknowledge button. When the alarm condition no longer exists, you press the Acknowledge button again to clear the visual alarm (alarm memory). The alarm can only be cleared with the Acknowledge button if the cause of the alarm has been removed. If the concentration still exceeds the alarm threshold, pressing the Acknowledge button does not clear the alarm. The voltage-free relay contact allows you to switch additional external signalling equipment such as the event reporting system EMS, horns, lamps in the case of alarm or error conditions. GM is suitable for control panel mounting with a mounting frame. A DIN rail clip is available for fast and easy mounting of GM to standard rails (DIN rail/EH50022). A sealing kit (IP 54) is available for rough application conditions.
