operation at the factory.
3.3 Testing
The RED1 detector uses ongoing self-test functions which will indicate a
fault if any of the functions fail to pass.
If an end-to-end test is required, the detector may be put into alarm
using butane lighter (Bic) with a flame approximately 1 inch high. Hold
the lighter about 1 foot directly in front of detector's face. The detector
should alarm almost immediately.
A 1 sq. ft. pan with 1 inch of water and 1/8 inch of gasoline (heptane) set
at the maximum distance set by the sensitivity settings may also be
used. The detector should alarm within 5 seconds of the fire becoming
fully involved.
A factory approved test device may be used to put the detector into
alarm.
NOTE: Because of the danger involved with fire testing all safety precautions
must be observed. In addition, should an extinguishing system be
connected, the outputs to the extinguishing system should be
disconnected during testing.
4. Maintenance
All fire protection systems should be inspected in accordance with NFPA 72,
or the appropriate local codes.
The self-test functions incorporated in the detectors reduce the need for
most regular maintenance procedures. If a detector indicates a fault, use the
troubleshooting section of this document.
4.1 Lens Cleaning
The most common fault is a UV Test Fault. Regular cleaning of the
Lens will diminish this type of fault. The frequency of cleaning will
depend on the cleanliness of the area where the detector is installed and
how the detector is mounted. A detector that is pointed down should
require less cleaning than one that is pointed up. An area which has lots
of oil particulates or dust will require more frequent cleaning than one
that is oil and dust free. The frequency of this fault will indicate how
often cleaning is necessary. If the device is failing the “UV Test” too
often, it may be necessary to install a dust shroud, realign the detector,
or change the detector's location.
To clean the lens, wipe the lens surface and grill with a clean lint free
cloth. If more extensive cleaning is required use denatured or Isopropyl
alcohol and a clean lint free cloth. Do not use any silica-based solvents.
(Most common glass cleaners are silica based and should not be used
to clean the lens).
