EXTINGUISHANT CONTROL PANEL

PEMALL Extinguishant Control Panel allows the functionality of the system to be extensively modified. It offers outstanding value and performance for all small to medium fixed firefighting installations which is designed and manufactured to the highest standards in a quality controlled environment and with UL and FM approvals. Provided with three initiation circuits as standard, release can be configured to activate from any combination of detection zone inputs to allow (among other combinations) any two from three type activations such as would be required for detection in the ceiling void, room and floor void applications.

FEATURES

• Any single zone or any combinations of zones can be configured to release UL864
• Listed Configurable releasing duration up to 5 minutes in 5 second steps
• Zero time delay upon manual release option
• Compatible with I.S. barriers
• Built in Extract Fan control
• Non-latching zone input option to receive signals from other systems
• Countdown timer shows time remaining until release
• Configurable releasing delays up to 60 seconds in 5 second steps
• Three initiation circuits as standard
• Configurable detection delays
• Configurable first stage NAC delays Supports up to seven, four wire status indicators

AUTOMATIC EXTINGUISHER CONTROL PANEL

Pemall Automatic Extinguisher Panel is specifically designed for use in areas housing expensive, dangerous or irreplaceable items of equipment, it features an intuitive 128 x 64 pixel display that gives clear and concise feedback to the user, installer and commissioning engineer. It has six monitored inputs (including hold & abort), 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.

FEATURES

• Functions as a standard 3 zone fire panel with additional circuitry for controlling the release of fire-suppressing gas.
• Unique 128 x 64 pixel graphic display
• Any combination of activated zones can be programmed to automatically start the panel’s extinguishant release sequence.
• Manual release button and two keyswitches.
• Built in Extract Fan control
• 3 conventional sounder circuits (two x 1st stage, one x 2nd stage)
• Powerful 3A EN54-4 switch mode PSU.
• Wide range of monitored inputs and auxiliary outputs.
• Abort and hold inputs.Time-stamped event log.

Photo-electric smoke indicators solidify a beating LED arranged in a chamber inside the cabin of the identifiers. The chamber is expected to restrict light from any external source. At an indicate the LED is a photo diode which consistently does not select the area of light created by the LED. If there should be an occurrence of smoke from a fire entering the chamber, the light pulse from the LED will be scattered and subsequently enlisted by the photo diode. If the photo diode “senses” smoke on the two following pulses, the indicators changes into the caution state and the marker LED enlightens. The identifier lodging is unclear to that of the ionization indicators yet has a pointer LED which is clear in remain by state, in any case, conveys red light in caution.

THERMAL DETECTOR SERIES 65A

Thermal detectors work by utilizing a coordinated combine of thermistors to detect heat. One thermistor is presented to the surrounding temperature, the other is sealed. In typical conditions the two thermistors enlist comparable temperatures, at the same time, on the advancement of a fire, the temperature recorded by the uncovered thermistor will increment quickly, bringing about an irregularity, making the locator change into the caution state. Rate-of-rise detectors are intended to recognize a fire as the temperature increments, yet they likewise have a settled maximum farthest point at which the identifier will go into alert if the rate of temperature increment has been too ease back to trigger the locator prior.

IONIZATION SMOKE DETECTOR SERIES 65A

Ionization Smoke Detector Series 65A can be mostly found in airports, offices, museums and industrial areas. Pemall Series 65A joins well-demonstrated sensing innovations, together with advances in materials and electronics innovation, including an IC in view of that utilized as a part of XP95 simple addressable detectors. Having a wide working voltage of 9-33V, the Pemall Series 65A territory comprises of ionization, coordinating ionization and photo-electric smoke identifiers, 2 evaluations of warm finder and a standard base. Each sort of identifier has a LED which flashes constantly in stand by mode.
