Receiving-control fire device "LPI"

Designed for operation in the signal circuits as the converter unit between the thermal fire detectors DPS - 038 and alarm control fire alarm devices, PPS - 3, PTP - 2, "Signal 42", "Topaz", "EPOS - 004", "TULIP ".

To operate the instrument can be used DPS other types having internal resistance less than 100 ohms and formed emf In a fire for at least 20 mV.
The device is intended for use outside explosive zones at an ambient temperature of from - 5 to 55 ° C, relative humidity (92 - 98)% at 25 ° C, atmospheric pressure of 650 to 800 mm Hg
«JA» level input device configured to intrinsically safe circuits.

 

The device provides:

• signaling "Fire" a fire alarm control panel when an abrupt temperature drop in the DPS 50 ° C for not more than 5 s;
• automatic loop control lines integrity DPS device (open, short circuit) from the issuance of the signal "damage" when the loop fault;
• automatic control of voltage of the main and backup power sources and corresponding signals "Damage";
• separation of the signals "Fire" and "Damage", "Damage to the main power source" and "Damage to a backup power source";
• issuing signal "fire" 1 - 10 channels when triggered one SOT;
• issuing signal "fire" channels 1 - 2, 3 - 4, 5 - 6, 7 - 8, 9 - 10 when triggered DPS two respective channels;
• warning lights on the top cover of the device "Damage" channel number, "Damage to the main power source, " "Damage to the backup power source";
• serviceability znahoditsya control clock generator in the device, and issuing the signal "Damage" when it malfunctions.

 

SPECIFICATIONS
