Prescient3
Prescient3 прибор управления пожаротушением с дружелюбным пользовательским интерфейсом разработанный и произведенный по высшим стандартам. Прибор имеет расширенные опции конфигурации, но легкодоступен для монтажа, программирования и работы. Съемное шасси позволяет инженеру установить пустой корпус, а затем, на стации проверки , интегрировать внутренние элементы.
TECHNICAL DESCRIPTION
The prescient range of extinguishing panels is available in two variants - either as a gaseous extinguishant panel or a pre-action water sprinkler panel. Panels are housed in well-designed enclosures with partially-glazed doors. Steel parts are finished in a hard-wearing epoxy paint.
Three fully-monitored detection zones are provided. Zones 1 and 2 normally provide first stage and second stage fire conditions to allow extinguishant discharge (double-knock zones). The 3rd zone is an auxiliary zone for detection only purposes.The 4th zone is used as a manual release zone.
Two fully-monitored alarm circuits are provided, each rated at 1A and may have various configuration options via the engineers’ DIL switch settings. Two fully-monitored actuator/solenoid circuits, each rated at 1A, operate simultaneously upon “extinguishant release”.
The panel provides 0.5A output at 28V DC to operate interior/exterior status indicator units. Outputs for auto, manual and discharged are provided at 250mA each..
Eight normally-open inputs provide for remote evacuate, silence alarms, system reset, lock-off input, low pressure input, gas discharged pressure switch input, remote abort and remote fault. Clean contact relays are provided for first stage signalling, second stage signalling, system reset, common fire, common fault and system discharged.
Top-entry plastic grommets, bottom-rear entry plastic grommets (for mains) and rear entry knock-outs are designed to assist with cable termination.
