Annual Alarm Transmission Test

Q: Is the alarm transmission verification test generally performed by a fire alarm testing company on every device during an annual test/inspection? I also thought that this was a quarterly requirement. I would verify receipt and timing of transmission with the central station once a quarter during fire drills. Do I have this confused with another standard?

A: No… NFPA changed the standard on you. Under the 1999 edition of NFPA 72, which the 2000 LSC referenced, the requirement was quarterly to test your off-premises monitoring transmission equipment. But with the 2012 LSC, it now references the 2010 edition of NFPA 72 which changed it to be an annual requirement.

But do not make the mistake of just testing the alarm transmission to the central station monitoring agency. This needs to be tested to the fire responder’s location, be it the 9-1-1 center or the local fire department. Many hospitals make the mistake of testing the alarm transmission to just the central station monitoring your fire alarm panel, but the interpretation by CMS and many of the accreditation organizations is you need to confirm that the local fire department received the alarm signal. This can be accomplished during a routine fire drill whereby you do not notify the central station monitoring company but you do notify the local fire department that a drill will be conducted, and tell them to not respond. After you complete the fire drill, contact the fire department to confirm they received the call from the central station monitoring company, and to return to normal response mode.

This test is conducted annually on a general alarm… not on every device that you test.

Visual Inspection of Fire Alarm Devices

Q: A question came up recently on the NFPA 72 semi-annual visual inspections required for fire alarm system devices. Would the printed records from an intelligent fire alarm system suffice for the visual inspections on devices such as smoke detectors, pull stations and heat detectors?

A: I would say no, the printed records from an intelligent fire alarm system would not suffice for a visual inspection on the fire alarm system devices. Items such as the following must be visually inspected twice a year on a semi-annual basis:

Initiating Devices

  1. Duct Detectors
  2. Electromechanical Releasing Devices
  3. Fire-Extinguishing System(s) or Suppression

System(s) Switches

  1. Fire Alarm Boxes
  2. Heat Detectors
  3. Radiant Energy Fire Detectors
  4. Smoke Detectors

The reasoning for this decision is found in the NFPA 72 handbook, which states: “The visual inspection is made to ensure that there are no changes that effect equipment performance. Equipment performance can be affected by building modifications, occupancy changes, changes in environmental conditions, device location, physical obstructions, device orientation, physical damage, improper installation, degree of cleanliness, or other obvious problems that might not be indicated through electrical supervision.”

It is not uncommon to find ancillary hospital equipment placed or installed in such a way as to affect or obstruct the normal operation of some of these devices. Semi-annual visual inspections will find these issues before they affect the performance of the fire alarm system.

Generally speaking, the printed records from an intelligent fire alarm system would only suffice for documentation on the 2-year sensitivity testing requirement. Everything else would have to be confirmed through direct observation.
