TO CHANGE ALARM LEVELS
The QMI MULTIPLEX System is pre-set. However should the settings require adjustment and
the alarm level set lower, then the procedure is as follows:
1. During the setting-up procedure normal operation of the CMU is disabled.
2. With the key supplied, release the security switch which is fitted to prevent unauthorised
adjustment of the system.
3. Turn the key clockwise ¼ turn. The setting light will illuminate.
4. Place the magnetic pen flat against the circle marked 'ALARM SETTING SWITCH'.
5. Place the magnetic pen flat against the circle marked 'RAISE ALARM LEVEL' or 'LOWER
ALARM LEVEL' Raise and remove the pen away from the circle once for each increment
until the required level is reached. The level will be indicated on the digital reading.
6. Place the magnetic pen flat against the circle marked 'CHANNEL NUMBER' to set that
channel to the level indicated at the digital reading.
7. To set another channel repeat 5 and 6.
8. When setting is complete turn the key anti-clockwise back ¼ turn, this locks the system,
then remove the key.
9. After the key has been turned (see above-item '8'), it is possible to check that the
setting is correct by placing the pen on 'ALARM LEVEL' then on 'CHANNEL NUMBER'.
The new set level will then be displayed.
10. To reset any channel ALL above items MUST be repeated.
