Apollo AlarmSense Open Area Sounder Beacon - 55000-017

The Apollo AlarmSense Open-Area Alarm Devices are zone powered, mounted devices which are connected to an AlarmSense system. The Apollo AlarmSense Open-Area Visual Indicator (55000-017) is designed for use in situations where there is a risk that sounders will not be heard.

AlarmSense sounders and manual call points are fitted to the same zone as detectors. In quiescent state, the zone is powered at between 9V and 15V, nominally 12V, at which only detectors and call points operate. Sounders require 24V to operate. When an alarm is detected on a zone, the control panel increases the line voltage to 24V on that zone causing the sounders to produce a continuous 'Evacuate' sound. Any voltage-sensitive output devices - relay modules or other alarm devices - also operate. When the voltage is increased to 24V, the detector alarm current will reduce to 1.5mA. The detectors are latched in alarm until they are reset by reducing the voltage to less than 2V for greater than 1 second. Output devices will de-activate each time the voltage is reduced to 12V unless otherwise stated in their specification. It is possible to generate an 'Alert' tone by pulsing the supply voltage from 12V to 24V and the sounders configured to continuous output. Pulse frequency of 1 second on, 1 second off, is recommended for compliance with BS5839 Pt1.
