OPERATIONS MANUAL

GENERAL
1.1
IP 212-31 DIP-31 Threshold Photoelectric Smoke Detector (hereinafter referred to as the detector) is to be used in fire detection and fire alarm
systems to detect smoke producing fires in closed premises of buildings by sensing the light reflected by smoke particles in its sensing chamber and
sending a fire alarm.
1.2
Two LEDs on the detector provide information on the detector’s conditions, which can be Quiescent Conditions, Pre-Alarm, Fire Alarm, Fault, and
Contaminated Chamber.
1.3
The detector is to be brought into an alarm loop of a fire control and indicating equipment (unit), is powered via the alarm loop, and triggers fire
alarms by increasing the loop current as a result of reducing its effective resistance.
1.4
The detector is powered via an alarm loop of a control and indicating equipment (unit) such as Signal-10, S2000-4, Signal-20P, S2000-ASPT,
Signal-20M, Signal-20, which provides loop voltage up to 30 V and limits the current in a loop at a level not exceeding 20 mA. The minimum powering
voltage in the loop is to be 10 V.
1.5
The detector is intended for round-the-clock operation and is classified as a repairable and periodically maintained item.
1.6
The version of DIP-31 firmware is v.1.05.
1.7
The detector can be tested using a System Sensor remote test unit, or Astra-942 Laser Tester from the TEKO Company, or OT-1 Optical Tester from
the RUBEZH Company.
