Fire Alarm Control Panel, a device for receiving and announcing the location of a fire, based upon input from smoke/flame/heat detectors, manual call points, or pull stations. It also sends a signal to the FSCS to initiate programmed smoke control procedures. (This manual does not address ...
Experimenting with Balanced Mixers and Product Detectors. Paul VK3HN Suggests the MC1496 chip; Walter KA4KXX points to SSDRA circuits But it is on the air! Using the PA from a BITX40 module and an RD06. Put an OLD dial from Pericles HI8P on 15-10 version 1. Soul in the new mac...
Please cover the dust cover after the installation or room decoration, painting construction, so that the smoke detectors are contaminated. 2. The alarm function test of smoke detector should be performed every six months. 3. When the controller detects the cleani...
The release is always direct and independent of the condition of the automatic detectors. The programmed dual detector dependency does not apply for the manual release. The release via the input "manual release" is suppressed during an open door contact (see chapter 2.4.1) or if an external ...

In detection systems in which a central controller is connected to a number of transponders (containinq smoke/fire detectors) by a two-wire communication line, it is known to both supply power to the transponders and pass data to and from the transponders over the line. The controller perio...
The smoke detector circuit is normally calibrated to generate an alarm signal if a predetermined concentration of smoke is present in the smoke chamber. Smoke detectors presently used are adjusted at the factory according to an actual standard smoke concentration in a test chamber. Because of the ...
