Warning
Precautions for connecting door phone
- Do not directly connect the LOCK port of DPIM(Door Phone Interface Module)
to a commercial AC power supply to prevent fire and immediate breakdown of
the OfficeServ 12 system.
- Connect a DPIM to a DLI port only after connecting a door phone to the DPIM.
- The LOCK port of DPIM is standardized so that it is used only for controlling
a low voltage relay. Standard values are 5 VDC and 40 mA.
Do not install the system in a location near a heat source such as a heater.
This is to prevent fire.
Precaution for cleaning
Do not spray directly on the unit, and do not clean the unit with benzene, thinner
or alcohol to prevent fire and electric shock.
Do not wire the system during a lightning storm.
This is to prevent electric shocks caused by lightning.
Do not directly connect the external paging equipment or a common bell to
a commercial AC power supply.
This is to prevent fire and immediate breakdown of the OfficeServ 12 system.
Check whether the power is on before connecting a cable for battery connection.
Connecting the battery while the power is off may cause sparks, which can be
very dangerous.
Unplug the AC power cable before grounding the system.
Grounding the system while the AC power cable is plugged in may cause high
voltage, which can result in critical damage.

Caution
Caution for using battery
DC 48 V(6~40 AH) batteries should be used for OfficeServ 12. If the capacity of
the battery is too great, system malfunction may occur. If the capacity is too small,
the system may not operate properly during a power failure.
Precaution for wall mounting
- If the wall is made of plaster or brick, or if the building is a prefabricated one,
you should place a 2 cm thick wood plate on the wall to prevent damaging the
wall.
- It may be difficult to drive a screw directly into a concrete wall. In such cases,
make a hole using an electric drill and insert a bushing into the hole first, and
then insert the screw into the bushing. This is to prevent the system from falling
and breaking.
Do not install the system places subject to moisture or wetness.
Do not install the system near a bathtub, wash-bowl, kitchen sink, and laundry
tub, in a damp basement or near a swimming pool. Doing so may cause a
malfunction or shorten the life span of parts.
Do not disassemble, repair or modify at your discretion.
Contact your service center when repair is required.
Use only the power cable and battery indicated by this manual.
Use of an alternative power cable and battery may result in serious damage,
which will not be covered by the product warranty.
Connect the OfficeServ 12 system to an independent AC outlet.
SharingAC power with other devices can cause noise or malfunction due to
voltage drop.
