front of the telephone number/s you enter in the unit.
4. 0800 telephone numbers do not work with emergency telephones.
It does not matter which number
is programmed into the unit, it
always dials the same number

Problem
Solution
Only have one set of contacts on
the Alarm Push, these set off the
Alarm & Siren
1. Remove the two wires from the Alarm Push and wire directly to Terminals 5&6, then wire two
spares from Terminals 9&15 to the back of the Alarm Push.
Alarm Push button is not working
1. It may be that the Alarm Push button has not been pressed for long enough. Check Delays> In
Car Delay to see what delay has been set. The default is 3 seconds. Adjust accordingly, but do
not set as 0.
2. Check that the Alarm Push is wired to connections 9&15 without voltage.
3. Check if the circuit is N/O or N/C. If normally closed, in Settings> System Config, select N/C
Alarm Push
4. Place a Short/Wire Link across Terminals 9&15 – this should trigger the Memcom
+
alarm, if it
does then the problem is with the alarm push or the wiring.
The sound quality of two way
communication is poor
1. Check what the volume has been set to, and adjust up or down accordingly.
2. If sound quality issues continue, consider changing the location of the Memcom
+
unit, or move
wiring to reduce interference with the sound and allow sound to travel through the lift car.
3. If problems still persist, then it may be worth considering a COP speaker / mic accessory.
