Opticko-kouřový hlásič s paticí a reléovým výstupem ES Detect, 48 V DC
800361.10
The threshold value detector with relay contact 800361.10 comprises an optical smoke detector 800371 from the ES Detect series and a detector base 805592 which enables a direct connection to a 48 V DC power supply. The detector therefore does not need to be operated in connection with a fire alarm control panel. If the detector detects a fire alarm, a floating relay contact activates to transmit the alarm. The relay contact is normally open (NO) by default, but can also be configured as normally closed (NC) with a solder strap on the circuit board base. A typical use for this detector is to monitor mobile communication stations, e.g. BTS base transceiver stations.
