Fire Extinguishant Panel (Model EP-203)
FIRE EXTINGUISHANT PANEL (MODEL EP-203)
Fully compliant with EN 12094 part 1 (the European standard for Fixed Firefighting Systems – Components for Gas Extinguishing Systems), the panel epitomises quality, durability and reliability and is ideal for use in any area housing expensive, dangerous or irreplaceable items of equipment.
Featuring an intuitive 128 x 64 pixel 2-colour graphic display that gives clear and concise feedback to the user, installer and commissioning engineer, the panel also includes six monitored inputs, a time stamped log, adjustable flood times and volt-free changeover relays for fire, local fire, 1st stage active, 2nd stage active, extractor fan and fault.
The panel is supplied in an elegantly styled, durable enclosure with all of its electronics – apart from its powerful 3A EN54-4 switch mode PSU – mounted on a detachable metal bridge plate for ease of installation.
- One of the most powerful extinguisher panels of its class on the market with easy to program capability.
- Includes three conventional detector circuits & sounder circuits (2 x 1st stage and 1 x 2nd stage) which are all line monitored for open and short circuit faults.
- Able to program any combination of activated detector zones to automatically activate the extinguishant release sequence, which can be set to operate with or without a delay.
- Minimum six monitored inputs are provided, including Hold and Abort for suspending or cancelling the release sequence at anytime.
- Adjustable flood times.
- Alarm counter to record the number of occasions the panel has been in alarm.
- Time-stamped log.
- Support for an optional relay expansion board to provide reset, mode, discharged, hold and abort outputs.
- Support for up to two Solenoids or multiple Metrons type actuators and volt-free changeover relay contacts for fire, local fire, 1st stage active, 2nd stage active, extract fan and fault.
- System expansion for extra flexibility
- Can be connected to the EP203 via a monitored RS485 bus to include up to eight flush or surface remote status units, each with their own displays, manual release mechanisms and mode switches.
- Single gang economy status units without displays (8 per system).
- A host of other ancillary devices including system line terminators and hold off/abort buttons.
