MAINTENANCE - CLEANING
1) Remove the safety screw.
2) Remove the detector from its base.
3) Thermistor area: use a small, soft bristle brush to dislodge any obvious contaminants such as insects, spider webs, hairs, et c.
4) Thermistor area: use a small vacuum tube or dry, clean, compressed air to suck up or blow any remaining small particles away.
5) Wipe the exterior housing of the detector with a clean, damp, lint-free cloth to remove any surface film that can later attract airborne
contaminants.
6) Install the detector onto its base again.
7) Test the detector.
8) Reinstall the safety screw.

WARNINGS AND LIMITATIONS
Our devices use high quality electronic components and plastic materials that are highly resistant to environ-
mental deterioration. However, after 10 years of continuous operation, it is advisable to replace the devices in
order to minimize the risk of reduced performance caused by external factors. Ensure that this device is only
used with compatible control panels. Detection systems must be checked, serviced and maintained on a
regular basis to confirm correct operation. Smoke detectors may respond differently to various kinds of
smoke particles, thus application advice should be sought for special risks. Detectors cannot respond correct-
ly if barriers exist between them and the fire location and may be affected by special environmental condi-
tions. Refer to and follow national codes of practice and other internationally recognized fire engineering
standards. Appropriate risk assessment should be carried out initially to determine correct design criteria and
updated periodically.
Use only in Taurus fire detection and alarm systems.
