Trouble Shooting Guide

No picture appears on the monitor (blue or white screen)
Check that all wires are connected and connected in the correct configuration
Check that the voltage at the back of the monitor across terminals 5 and 6. The
voltage should be over 14.3vDC, if it is not then the handset will not function
correctly
One or more monitors are not working but others are
Check that all wires are connected and connected in the correct configuration
Swap the monitor positions around. This will identify if the issue lies with the
monitor or the location of the monitor. For example - monitor 1 does not work,
monitor 2 does, when swopped around monitor 1 works in monitor 2's location.
There is a problem with monitor 2's location (wiring problem etc)
If no monitors work
Check that power is supplied to each monitor and that the specifications for
installation have been followed correctly
Check that all wires are connected and connected in the correct configuration
Run a new length of short cable and connect a monitor next to the camera, this will
rule out any issue with lack of voltage and/or cable run length. The PSU's supplied
with each monitor must be used and the cable length from PSU to monitor must not
exceed 10m
In multi apartment systems if more than one apartments monitor rings
simultaneously
Remove jumper J3 from all handsets
Please also check
The monitor and the outdoor station connections are colour coded - ensure the
colours are matched
Connect to the CN1 terminal on the back of the handset for a single outdoor station
system
Connect to the CN2 terminal on the back of the handset if a 2nd outdoor station is
used
The electro-magnetic lock (MAGLOCK) will not energise
The electro-magnetic lock (MAGLOCK) requires 12vDC to lock. Trace the 12vDC from
the lock to the power supply source and test that sufficient power is reaching the
lock
If using the EVBPS
Please ensure that the N.C switch is in position for an electro-magnetic lock release
Please ensure that the N.O switch is in position for a Yale style lock release
The electro-magnetic lock (MAGLOCK) does not have enough holding force
Check the voltage and ensure that the rubber washer has been fitted along with the
armature, this will enable enough movement for the magnet and armature to line-up
correctly as the movement allowed compensates for misalignments on the
door / frame
