- in the case of a device without a separate power source, connect the 2 wires
(YnTKSY) with the power supply from terminal P19.
An example of both variants of connection is shown in
Diag. 4.
NOTE - the maximum load on the alarm loop terminals is 110 mA!
17.
Start-up.
Before switching on the power supply, check if the leads are connected
properly.
Note: the leads should be placed and connected in accordance with relevant
standards and basic rules for wiring. First switch on the 230 V mains voltage, and
only then connect the batteries. The reverse order is not recommended because
of a large current surge that occurs during the charging of the condenser in the
power supply adaptor.
18. In a correctly operating unit, the following LED indicator are on: READY, POWER
SUPPLY, and VENT OPEN. When the CLOSE VENTS button is pressed, the
VENT OPEN diode begins to blink and then switches off after about 5 minutes.
When the actuator is in operation, the VENT OPEN diode keeps blinking.
19. In order to check the operation of ventilation, the weather monitoring unit should
be disconnected. The weather monitoring unit blocks ventilation for several
minutes after the wind has ceased, and in case of rain the sensor needs to get
dry, which takes even more time.
20.
The LEDs on the inside of the unit’s door make detailed defect identification
possible. To test their operation, press the TEST button and hold it down for
about 1 s. To test the operation of the audible alarm indicator, press
simultaneously the TEST and RESET buttons.
Note: in order to connect the unit you should use leads which satisfy the
requirements of current regulations.
5. Instruction manual for checking connection and performance of
the mcr 9705 control unit
For reasons of operational safety and reliability of the fire protection system, after
installing the control panel, check the device by following instructions.
1. Check the correctness and reliability of connection of all cables (main power,
input and output lines, line continuity resistors) in accordance with with Operation
Manual and the installation design.
2. Check the value of the power supply voltage of the control unit - it should be
230 V

, 50 Hz.
3. Perform the control panel start-up in accordance with the Operation Manual
(Chapt. 4, par. 17, 18).
4. Check whether the control panel remains in the normal operating state
(Chapt. 3.1).
5. After min. 12 hours of charging the batteries, check the voltage at the battery
terminals. The measurement must be carried out in the normal operating state
(Chapt. 3.1).
The voltage at the battery terminals should be in the range of 26.5 ÷
28 V =
.
6. Perform auditing of optical and acoustic signalling
(Chapt. 4, Par. 18, 20).
7. Check the correctness of fault detection by the control unit: damage to the sensor
line (e.g. take out the last sensor from the socket), damage to the RPO button
line (e.g. to open the RPO line, P9 terminal), damage to the actuator lines (e.g.
