Alarm systems have many components that can fail or lose effectiveness over time. SDi Fire can provide you with alarm component testers to make sure your alarms don’t degrade and make sure they are operating properly.Over time alarm components can corrode and become contaminated with dirt and various other contaminants. An essential part of fire safety is making sure that these components continue to work the way they should. Our alarm component testers are extremely accurate and can help make sure your systems are working at peak efficiency. When adhering to fire safety regulations you have to stay on top of your alarm systems. SDi Fire has the products to help you with testing your alarm components.
 Cell CheckerCell Checker is ideal for testing fire and security alarm systems. Using pulse load technology it provides a comprehensive test of a battery’s state of charge and condition. Battery voltage alone is not a reliable parameter for determining remaining capacity and condition; it also does not indicate whether the battery will be able to deliver power when placed under load. Rather than simply displaying a voltage reading, Cell Checker determines a battery’s remaining power capacity by measuring its ability to maintain voltage levels while under load.
 dB CheckerdB Checker is ideal for measuring the sound pressure levels for audible alarm notification appliances as mandated by the National Fire Alarm & Signaling Code. Merely “listening” or utilizing any sound level meter available is not a reliable method of testing audible alarm notification appliances. Many of the meters currently on the market do not meet the requirements for NFPA 72. dB Checker conforms to ANSI S1.4a, which is required to meet the standard set forth in the latest edition of the National Fire Alarm Code. Two models are available to support either A frequency weighting (dB02) or A to C frequency rating (dB01).
Duct Checker
Duct Checker is the ideal device for annual testing to
ensure that the duct detector will sample the
differential pressure via the sampling tubes, as
required by NFPA 72. According to NFPA Chapter 14, “duct
smoke detectors utilizing sampling tubes shall be tested
by verifying the correct pressure differential between
the inlet and exhaust tubes using a method acceptable to
the manufacturer to ensure that the device will properly
sample the airstream.” Duct Checker is manufacturer
approved, easy to use, and ensures accurate results.
  Power Checker
Power Checker provides a comprehensive means of testing
the state of charge or state of power for more than 30
battery types. This microprocessor -controlled
instrument is designed for commercial or home use and
tests popular primary (non-rechargeable) and
rechargeable batteries using a patented, high accuracy
pulse load test. After a fully automatic test cycle,
percentage of remaining battery capacity is indicated on
the LED bar display. Battery types are clearly labelled
next to appropriate contacts. The negative test
lead/probe conveniently stores in seam at side. It’ s
easy to use, and test results are easy to
AV CheckerAV Checker is the ideal device for annual testing to ensure that the duct detector will sample the air velocity as required by NFPA 72, and according to manufacturer’s instructions.
