3.3 Optical alarm signaling
The alarm is signaled by steady light of the red LED, thus making it easier to locate the
detector which issued the alarm. If the detector is mounted in a hard-to-reach location and
the LED is not visible, a remote alarm indicator installed in a visible place can be connected
to the detector.
4. Installation
The detectors are designed for indoor installation. In the typical home or office applications,
the detector should be installed on the ceiling, at a distance of at least 0.5 meters from the
walls or other objects.
Do not install the detector in places with high concentration of dust, with
formation and condensation of water steam and/or in the vicinity of air
conditioning vents.
The detector should not be installed near heaters and cookers.
The detector is designed for installation in the DB-100 base, to which cables are connected.
Having installed the detector into its base, protect it temporarily with the plastic dust cover
included in the detector delivery set, if any work which might cause fouling of the detector is
being carried out in the building.
It is advisable to keep the dust cover in case repair work is conducted in the future.
5. Maintenance
The detectors should be subject to regular checks to ensure they are working correctly.
Periodic checks should be conducted at least every six months.
5.1 Cleaning the optical chamber
The DMP-100 and DRP-100 detectors are monitoring the state of the optical chamber.
Deposition of dust in it may lead to malfunctioning of the device. It is recommended that you
have the optical chamber cleaned at least once a year. Cleaning the chamber is necessary
when the LED indicates fouling of the chamber (one flash every 30 seconds).
Below, the procedure of cleaning the DMP-100 optical detector is described. For the
DRP-100 detector, in which no thermistor is installed, proceed in the same way, skipping the
steps 4 and 8.
1. Turn the detector counter-clockwise (Fig. 3) and remove it from the DB-100 base (Fig. 4).
2. Pull the release lever to unlock the electronics module and turn it counter-clockwise
(Fig. 5 and 6).
