Product overview
Relay output signal smoke detector, referred to as "networking smoke, also known as on-off smoke, built-in relay, can switch output signal. Suitable for shopping malls, hotels, shops, warehouses, and other civil and industrial electrical room place fire pre-alarm. Connected to the smoke detector with high sensitivity, stable and reliable, low power consumption, beautiful and durable, convenient use, etc, can be used with security systems.
The performance characteristics of
New type of high performance sensor can effectively detect smoldering fire
Connected to the smoke detector using intelligent microprocessor, a variety of fire model algorithm to eliminate false alarms, passive relay contact output can be set up
Connected to the smoke detector with wide voltage design, convenient for engineering applications
The smoke chamber adopts insect nets design, avoid insects go call the police
Leds - display alarm work normally and alarm status
The shell adopts fireproof ABS engineering plastics, the beauty is generous
The performance parameters
Power supply: DC9V ~ DC28V.
Electricity flow, static current ua 200 or less; Alarm current 45 ma or less.
Working temperature: - 10 ℃ ~ + 50 ℃.
Relative humidity: 95% RH or less (40 ℃ + 2 ℃).
Alarm sounds: 80 db/m or higher.
Output format: passive relay contact output can be set to (NO/NC), contact capacity 1 a / 24 VDC, the factory default output is normally closed.
Smoke sensitivity: 0.15 ~ 0.3 dB/m.
Functional specifications
Work: under normal circumstances, connected to the smoke detector about every 5 to 6 seconds will shine. Connected to the smoke detector automatic test environment, the variation of smoke concentration and automatic sensitivity compensation according to the environmental conditions. When the smoke concentration near the alarm value, networking smoke detector to speed up the smoke concentration trend of intelligent computing, at the same time, the alarm light began to shine. If the operation result reach or exceed alarm value, detector keep normally on red LED lights, sound, and start the relay output. When the smoke concentration returned to normal, connected to the smoke detector automatically return to normal working condition.
Note: when connected to the smoke detector alarm, passive output relay contact, contact capacity of 1 a / 24 VDC, through the probe on the PCB jumpers, set to normally open or normally closed contact output. To jump line factory default Settings for the normally closed contacts.
Installation instructions
Connected to the smoke detector base installation dimension of 47 cm - 88 cm. When installation, on the ceiling are 60 mm apart on the location of the two mounting hole 5 mm in diameter, with a new plug screw and detector base on the ceiling. Connect the power cord on the base of terminal 2, terminal 6 (nonpolar), passive relay contact output lines connected to the base terminal 3, terminal 5. Button will probe in the right direction on the base, press down the screw clockwise. It starts working just by turning on the power supply.
