LTC 8100, LTC 8200, LTC 8300 Series | Instruction Manual | Installation Procedure

Connect any 2-conductor shielded wire (the shield and

ground wire are both connected to the connector pins

labeled G) between the alarming device (contact closure

or logic level) and the appropriate Allegiant input. Use

the straight slot side of the supplied offset screwdriver to

tighten the terminal block screws. The alarm input

numbers are marked on the removable connector block.

Note that every two alarm inputs share a common

ground connection. The total wire loop resistance

should not exceed 1,000Ω. Input #1 corresponds to

camera #1 in the Factory Default Settings, but this

relationship can be changed via programming with the

optional LTC 8059/00 MCS for Windows package or

LTC 8850/00 GUI software package.

Allegiant units also provide isolated alarm relay outputs.

An alarm output is typically used to activate the alarm

input of a security DVR/VCR or other alerting device. A

VCR is normally programmed to change recording

speeds from a slower time lapse mode to a faster real

time mode upon alarm activation. Operation of the relay

outputs depends on the system configuration for

responding to alarm events. The alarm output relays

activate accordingly under the following conditions:

1. Relay 1 activates if the system is set to use the

Basic alarm response mode, and an alarm occurs

on any system monitor. Relay 1 deactivates after

all alarms have been removed from the inputs.

Relay 1 also deactivates if the system (monitor or

alarm(s)) is disarmed by an operator via the

keyboard. Pressing Acknowledge on the system

keyboard does not deactivate Relay 1 since the

alarm video follows the contact applied to the unit

in this alarm response mode. Other relays are

not used in this mode.

2. Relay 1 activates if the base system is set to use

the Sequence & Display alarm response mode

and an alarm occurs on any system monitor.

Relay 1 deactivates after all alarm videos have

been acknowledged (by pressing the

Acknowledge key) via system operator(s) from

all system monitors. Relay 1 also deactivates if

the system is disarmed (either the monitor or

the alarm(s)) by an operator via the keyboard.

Removal of the alarm input does not deactivate

Relay 1 since the alarm video(s) are not

dependent on duration of the contact applied to

the unit in this alarm response mode. Other relays

are not used in this mode.

3. If the base system is set to use the Autobuild

alarm response mode, and an alarm occurs on

system monitors, the relay corresponding to the

monitor number activates for the duration that the

corresponding alarm input is applied to the unit.

The relay deactivates if the monitor associated

with the relay or if the alarm(s) being displayed on

the monitor is disarmed by an operator via the

keyboard. Pressing Acknowledge on the system

keyboard does not deactivate the relays since the

alarm video follows the contact applied to the unit

in this alarm response mode.

4. If the VersAlarm Group table screen in the

PC- based LTC 8059/00 MCS for Windows

package or the LTC 8850/00 GUI software

contains an alarm group that includes monitors,

and the Monitor option has been selected in the

Relay Action column, the corresponding relay

activates for the duration the alarm video remains

on the monitor. The relay deactivates if the

associated monitor (or the alarm(s) being

displayed on the monitor) is disarmed by an

operator via the keyboard. Pressing Acknowledge

on the system keyboard does not deactivate the

relay unless this feature has been selected for the

associated alarm group. If the Monitor option has

been set to 1 in the Group table, only Relay 1

activates when monitors in that alarm group

become alarmed.

Typically, any 2-conductor wire can be used between the

rear panel terminal block containing the relay outputs,

and the VCR alarm input. Use the straight slot side of the

supplied offset screwdriver to tighten the terminal block

screws. If another external device is to be controlled, do

not exceed the relay ratings of 1 A, 40 VAC/DC.

6.9 Satellite Configuration Installations

Due to many variables, only general guidelines will be

covered for installing satellite systems. Refer to the

APPENDICES of this manual and either the

LTC 8059/00 MCS for Windows or LTC 8850/00 GUI

software manual for additional information on satellite

systems.
