System 2 Installation / Programming Manual
Main Relays
Each System 2 has two independently controlled SPDT "C" form heavy duty relays with contacts rated five
amps at 30 volts DC. They are fully programmable and may be activated by Keypads, Cards, Request-To-Exit
switches, time schedules, and/or using the "Override Outputs Option" from any programming location including
off-site remote locations using modems. These relays can be programmed for a momentary time of
1 - 255 seconds or latching (on/off).
Note: The main relay time for a two-door System 2 (2016) can be programed for a momentary time up
to 65535 seconds (18.2 hours).
These "dry" relay contacts may be used to activate door strikes, electromagnetic door holders, alarm system
controls, or to control any momentary or on/off device including energy management devices, lights, and air
conditioning systems. Each time a relay is activated/deactivated, an event is created, stored in memory, and,
with the addition of a printer, printed with event data including time & date. Because they are "C" form, they
may be wired "fail-safe" or "fail-secure". In addition to the “C” form contacts, main relays also have an “A”
form contact rated five amps at 30 volts DC which also can be used to control door strikes or shunt existing
alarm contacts.
Auxiliary Relays
The System 2 has two SPDT auxiliary relays rated five amps at 30 volts DC. These relays can be triggered
from any System event. When the Second Door is activated, these relays can also be triggered by time
schedules or codes. These relays can be programmed for a momentary time of 1 - 255 seconds or latching
(on/off).
Voltage Outputs
The System 2 has two voltage outputs which are capable of switching to negative (-) up to 50 ma. These
outputs can be triggered from various System events. If the Second Door is activated these outputs can also
be triggered by time schedules or codes. These outputs can be programmed for a momentary time of 1 - 255
seconds or latching (on/off).
The power source for these outputs may be obtained from Terminals #28 (+5V) or #29 (+12V). A relay can
be wired between each voltage output and Terminal #28 (for a 5 volt relay) or #29 (for a 12 volt relay).
Door Ajar / Forced Entry Inputs / Time Cancel
The System 2 can monitor a “ normally closed” or “closed circuit” door contact to report a Door Ajar / Forced
Entry condition. Each System 2 has one input for each of the two doors. A Door Ajar condition is created
when a door is held or propped open for more than five seconds after a valid code or Card entry. A Forced
Entry condition is created when a door is opened without being preceded by a valid code or Card entry. In
either condition any of the System’s Auxiliary outputs can be triggered.
Request-To-Exit Inputs
With the addition of a Normally Open “button” or Passive Infrared device connected to these inputs, the main
relays can be activated to release the door locks, log the event and trigger any Auxiliary output.
