Technical data sheet
The SEC-K system
comprises of a pressure sender unit and a 230volt gas solenoid valve.
The panel housing is an ABS enclosure, rated IP65, measuring 183mm high, 212mm wide & 97mm deep.
The pressure sender unit and the gas solenoid valve are supplied with a fixing kit for connection on site.
The pressure sender unit is wired to the control panel using single pair low voltage wire.
The connection terminals are marked “A & B” on both the sender unit and control panel connections.
The 230volt mains supply to the panel should be from a 3amp fused switch.
The solenoid valve is connected to the terminals marked “Valve” on the panel connections.
The connections marked “EM STOP” are provided in order that extra emergency stops can be operated by the
panel. Wiring of emergency stop buttons should be series normally closed, extra low voltage.
The connections marked “CM2 or PD switches are for the connection of a current monitor or pressure
switches for interlocking fans with the gas supply.
The connections marked “detectors” are for the connection of up to 16 devices including, Methane, LPG, Co2,
CO, Oxygen and temperature. Mixed devices can be connected.
At the time of installation
adjustments to the system can be made to suit the individual site, these include:
Auto stop timer, alarm sounder on/off, fill time and prove time for pressure proving to find the smallest leak.
All are factory set for a typical installation.
For guidance purposes only
, a let by and a tightness test can be activated by the engineer using the push
buttons on the circuit board. This is a diagnostic indicator. The Gas pressure readouts appear on the LCD
display indicating the pressure on both sides of the valve.
