Alto 818 Installation and Operation
3-2 P/N 66109074001 Rev. D
3.1 INSTALLATION PLANNING
The design of any access control system requires careful consideration of the specific security
needs of the owner and how the capabilities of the available system hardware can be made to
meet those needs. The site security requirements should be thoroughly discussed with the
owner before the system hardware is selected and an installation plan is drawn up.
3.1.1 SAFETY PRECAUTIONS
The safety precautions listed below should be taken into account when designing an installation,
and they should be thoroughly reviewed before the plan is finalized. It should be noted that the
Alto 818 cannot be used as the primary system for fire safety monitoring locations. However, the
ACU can be used to monitor auxiliary outputs to provide supplemental information.
Safety precautions to be observed are as follows:
1. National, state, and local building and fire codes must be followed.
2. The installation plan must permit manual exit from controlled doors in the event of fire or other
general emergencies.
3. The installation plan must provide for appropriate site access to emergency personnel in the
event of a fire or any other emergency.
A. The system terminal must be accessible during an emergency so that the doors can be
unlocked. Circuits that will enable monitor points to trigger the unlocking of specified
emergency doors may be useful.
B. In the event of a power failure, emergency entrances and exits must unlock automati-
cally. Locks on emergency doors must be rated for continuous duty. Magnetic locks,
especially low current versions with inductive damping, are recommended for such
applications.
4. Considerations should be made for various types of emergencies such as fires, intrusions,
medical alerts, earthquakes, etc. Some codes require that emergency personnel be able
to shut off all electrical power to a building from one outside location. This requirement may
or may not apply to backup batteries for an uninterruptible power supply.
5. The system must be designed to avoid the accidental triggering of alarms.
6. Products which are not UL 294 listed may not be used in an access control system which must
meet UL 294 specifications.
