Sirena Exterior ELMDENE™ QuartzELMDENE™ Quartz Outdoor SirenSirena exterior Quartz blanca/azul de alta eficiencia operativa. Consumo de 17mA en reposo, y 130mA en activo. The Quartz sounder is used for notification of an alarm condition as generated within an intruder, holdup or other alarm system. In response to commands from the alarm system control panel, the Quartz will emit a high intensity sound and/or operate a visual flash. The Quartz will detect any attempt to gain unauthorised access to the sounder by removal of the cover, or any attempt to remove it away from its mounting surface. This will generate a tamper signal which is normally fed back to the alarm control panel. The Quartz is classified a self powered sounder and has an on-board battery which is recharged via the external power source. This battery is used to operate the sounder if the external power is removed. The Quartz can be configured to self actuate (SAB Mode ON) in the event that a tamper condition is detected or the external power to the sounder is removed. To assist with commissioning, the Quartz has an Engineer Mode to provide silent start-up. Two Comfort LEDs are used to provide a heart-beat type visual indication when the Quartz is not sounding.
