Smoke and Heat Exhaust Control Unit mcr 0204. User Instruction Manual.
Strona 9 z 16
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 the case of rain the sensor needs to get dry, which takes even more time.
Note: in order to connect the unit you should use leads which satisfy the requirements of current
regulations.
6. INSTRUCTION MANUAL FOR CHECKING CONNECTION AND
PERFORMANCE OF THE MCR 0204 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 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
(chapter 5).
4. Check whether the control panel remains in the normal operating state (chapter 4.1).
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 (chapter 4.1). The
voltage at the battery terminals should be in the range of 26.5 ÷ 28 V =.
6. Check the correctness of fault detection by the control unit (paragraph 4.7): damage to
the detector line (e.g. take out the last detector from the socket), damage to the RPO
button line (e.g. to open the RPO line, P6 terminal), damage to the actuator lines (e.g.
open the actuators line, the control panel in mode smoke exhaust), power supply damage
(e.g. 230 V disconnect), battery detection (e.g. disconnect the batteries). Tests should be
performed in a normal operating state for any potential damage. In each test case, the
fault condition should be detected and signalled on the front panel of the control unit, on
the service panel for selected faults, by means of the mcr RPO-1 emergency pushbutton
(if connected) and on the fault indication output (by ohmmeter control).
7. Check whether the control panel is correctly detecting alarms. Check all connected alarm
sources:
a) alarm from the RPO line (press the mcr RPO-1 emergency pushbutton),
b) alarm from the detector line (activate the detector),
c) alarm from the external alarm line (activate external device or open the line).
Tests should be performed in the normal operating state independently for each
connected alarm source. In any case, the alarm condition should be detected and signaled
by the control unit (chapter 4.4) on the front panel, on the service panel with the diode
of the proper alarm source, with the diode of the mcr RPO-1 (if connected) and on the
alarm signal output (ohmmeter control), and all connected fire devices controlled by the
control panel should be controlled.
8. If applicable, check that the daily ventilating function (chapter 5, item 5).
9. Check whether the control unit remains in the normal operating state after all tests have
been performed (chapter 4.1).
10. The control panel can be put into operation if all tests have been completed correctly.
Only an efficient and properly connected control unit can work in fire protection systems.
In the event that at least one result of the above tests is not correct, the control panel
cannot be used in security systems and should be restored for proper operation.
