Fireproof GPRS Wireless WIFI GSM Alarm System Work With Smoke Gas CO Detector APP Control

Wireless WIFI GSM Alarm System Description:

1, Rated working voltage: AC220V
2, Alarm & protection when residual current exceeds the limit.
(1) Alarm set value: 50mA-999mA (±5%) continuously adjustable, the step
size is 1mA.
(2) Rated residual operating current: 30mA-999m continuously adjustable.
(3) Factory parameters of this device have been set to the default values as follows:
Rated residual current warning: 540mA
Rated residual current alarm value: 600mA.
(4) Rated residual non-operating current: 20mA-1000mA, continuously adjustable.

3. Protection action time: < 0.5s.
4, Alarm sound: > 70db;
5, Alarm disconnection output: switch type, contact capacity AC250V/3A;
6, Communication method: CAN communication with the host computer <10km
7, Environmental conditions
A. Ambient temperature: -20°C+40°C
B. Relative humidity: 10%-90%
C. Altitude: no more than 3000m
D. Places: rainproof facilities
8. Installation method: rail installation.
9. Operating indicator: It indicates whether the detection controller is running
normally. The indicator flashes during normal operation.
10. Communication indicator: It indicates whether the communication between
the device and the host computer is normal. The indicator flashes during
normal communication.
11. Alarm (disconnection) indicator: When current leakage reaches the alarm
value, the indicator is constantly on with alarm sound. This indicates emergency
like leakage or overload in the power line, reminding the staff to solve the
problem in time.
12. Warning indicator: When the current leakage reaches the warning value
(90% of the alarm value), the indicator is constantly on.
