This is known as the quiescent current. Fire Alarm Notifica-tion appliances are powered by one or more PC4702BP panels connected to the Combus. The current when in alarm with all WDs and ATE activated.
In order to calculate the standby battery size required the following formula can be used. If you know which batteries have been supplied you can enter the battery size into the bottom box. In order to calculate the standby battery size required the following formula can be used-Battery Size Standby time in Amp Hours 125 x TALM x IALM TSBY x IQP IQD Where.
Standby time less 30mins - typically 115hrs but could be up to 235hrs depending on system Standby load Alarm load Alarm period is assumed to be 30min 2x 15m Note the calculator includes an ageing factor of 25 over the expected life of. 20 mA mA 1 max Alarm. Definitions and example of the above.
120 mA mA Alarm. D6510 MPU UPDATE KIT V782. C min I1 x T1 I2 x 125.
03022021 Simply fill in your quiescent load standby load and alarm load both in milliamps and then your standby period in hours to accurately calculate the minimum battery size required for the panel. Hour is most common time. Batteries Standby Battery Calculation The following formula can be used to calculate the appropriate standby battery size.
Burglar alarms are generally reliable but if the internal battery is flat and will no longer hold charge it should be replaced as soon as possible. Responsibilities of the Client. 01112010 Standby Battery Calculation.
D6541 LC UPDATE KIT V104. The app then outputs whether the battery is sufficient and if not which battery size should be used. D10024 Standby Battery Calculator.
140 mA mA 5220 Direct Connect module 1 Standby. C min I1 x T1 I2 x 125 Definitions and example of the above I1 Standby current from the fire alarm panel 005 Amps T1 Standby time assume category L1 24 Hours I2 Full alarm current from panel 03 Amps. - British Standards compliant - No Adverts - Free to use -.
This column X This column Current per number of devices C-6000 Panel 1 Standby. Each of the PC4702BP panels has its own standby battery. In accordance with Annex C Clause C 1 To calculate the battery capacity it is necessary to take two current readings.
24072008 do the maths - your counting the battery down to fully discharged so a 7AMP battery could supply 930ma for seven hours 575ma for 12hours etc but the regs say it has to disconnect at 10V IIRC so your formula is flawed. 12 Amp 500ma. Check with the local fire marshal or fire inspector to find out how long the alarms have to continue once the system is in alarm.
T ALM Maximum time in hours required for the alarm. 31102013 The following formula can be used to calculate the appropriate standby battery size. D6510 MPU UPDATE KIT V0800.
18092017 We have built this app for security engineers to easily calculate if the intruder alarm battery is sufficient by inputting the standby load standby time alarm load and current battery size. Simply fill in your quiescent load standby load and alarm load both in milliamps and then your standby period in hours to accurately calculate the minimum battery size required for the panel. I2 Full alarm current from panel 03 Amps.
I1 Stanby current from the fire alarm panel 005 Amps.
