KIT BOXSMART, KIT BOXPRES PLUS stairwell and escape route pressurization systems to EN 12101-6, 50 Pa

The pressurization kits KIT BOXSMART and KIT BOXPRES PLUS create overpressure in stairwells, elevator lobbies and escape routes to EN 12101-6. With the doors closed a pressure difference of 50 Pa is maintained automatically, and when the doors are opened the system increases the airflow and keeps the required air velocity in the opening.

Type
pressurization kit — control panel with a frequency converter + supply ventilation unit (CJHCH or CJBD) + (BOXSMART) motorized dampers with a smoke detector
Standard

Description

The basis of KIT BOXPRES PLUS is a control panel and a supply unit CJHCH (axial) or CJBD (centrifugal), while KIT BOXSMART additionally has one or two motorized dampers with a smoke detector DAMPER BOX SMART in versions 1D and 2D, which close the air intake when there is smoke. The panel contains a frequency converter programmed for 50 Pa, a high-precision differential pressure sensor, a circuit breaker, Ready, Alarm, Fire and Run indicators, a TEST selector and a 0-AUTO-MANUAL selector for firefighters. Potential-free FAULT, START and FIRE ACTIVATION contacts together with Modbus RTU provide the connection to the BMS. The enclosure is metal, vandal-proof, IP66, with a lock. A safe mode on pressure sensor failure, automatic restart and retention of activation when the alarm signal disappears are provided. The panel works with asynchronous motors and also with IPM and RM.

How to choose

There are solutions for 50 and 30 Pa, including one with a test report to EN 12101-6:2022, and the solutions can also meet NFPA 92 requirements. BOXSMART II and BOXPRES PLUS II have a standby fan with automatic changeover. BOXSMART FLAP is designed for fans with a WALL or HATCH hatch, and KIT BOXSMART EC uses the CJK/EC unit with EC motors. The remote panel CM-SMART shows the status and lets firefighters switch the system on and off manually, and SI-CALENDAR adds an input for daily ventilation.

FAQ

What pressure difference does the pressurization system maintain?

50 Pa with the doors closed, and solutions for 30 Pa are also available. When the doors are opened, the frequency converter increases the airflow.

What is included in the kit?

A control panel and a matched supply unit CJHCH or CJBD, and in BOXSMART also dampers with a smoke detector. It is enough to connect the power supply, the fan and the fire alarm signal.

Is there fan redundancy?

Yes, the BOXSMART II and BOXPRES PLUS II versions have a standby fan with automatic changeover.

How is the system connected to the BMS?

Via Modbus RTU. There are also potential-free FAULT, START and FIRE ACTIVATION contacts.

What is the ingress protection of the control panel?

A metal vandal-proof IP66 enclosure with a lock.
