PART 5 INSTALLING ADDITIONAL FEATURES
The Infinity system has many standard features which can be connected during installation. Only card
readers, built-in modems and CCTV cameras must be ordered as options.
It is critical to proper system operation that the specified cable types and grounding procedures be
used. If not, outside electrical interference (i.e., nearby power and control cables or radio station
broadcast towers) may cause erratic card or keypad readings or system resetting or lock-up.
WARNING: Before hooking up any of these features, disconnect power from the unit.
A. POSTAL LOCK INSTALLATION
If mail boxes are inside a controlled area, the post office requires their own lock be installed.
•
A postal lock kit is provided with each system, which includes installation instructions.
•
When the kit is installed, a postal carrier turning his key in the lock will activate the relay for a
programmable period of time.
•
A record of this activity will be stored in the transaction memory buffer, and printed if this
system is equipped with a printer.
B. AUXILIARY OPENING/REQUEST ACCESS DEVICES
Any contact closure device (i.e. Knox box or exit button) can be wired to relays 1 and/or 2.
•
To activate relay 1, connect the device to "Status 1" and "Common" on TB 8.
•
To activate relay 2, connect, "Status 3" and "Common" on TB 7.
•
Use shielded cable and connect the shield to the ground screw shown in Figure 3 or Figure 4.
•
When a contact closure occurs, the system will activate the appropriate relay for a
programmable period of time. A record of this activity will be stored in the transaction memory
buffer, and printed if this system is equipped with a printer.
C. DOOR POSITION SENSING
Each Infinity can monitor the position of two doors and take action if the door is pried open or held
open for more than a minute after the relay deactivates.
•
The system can call a telephone number to report this condition and/or close a relay to activate
any device you have hooked to it (i.e., light, siren, CCTV).
•
If the door shuts before the relay times out, the relay is deactivated to stop "tailgating".
•
To use this feature, install an NC (Normally Closed) switch in the door frame so the switch is
depressed when the door is closed.
•
Wire the NC and COM switch terminals to "Status 2" and "Common" on TB 8 for door 1, and/or
•
Wire the NC and COM switch terminals to "Status 4" and "Common" on TB 7 for door 2.
•
If the door is located more than 25 feet from the Infinity, use shielded cable and connect the
shield to the ground screw shown in Figure 3 or Figure 4.
