ABOUT SECURITY ZONES
Zones 1-8 on the controller and zones 9-24 on the expander may be configured as security zones, fire zones, temperature zones, or
auxiliary inputs. Zones 7 and 8 on the controller and zones 9-16 may also be configured as a PESM. Zone 8 is the only input that
can be configured as a UL Supervised Fire Zone (required for UL installations). Any other zone may be configured as Fire Zone,
however, it is not recognized by UL as a Supervised Fire Zone.
An external 1000-ohm end-of-line zone resistor is required for all zones unless the Setup item ZONE RESISTERS is set to "No".
If the Setup item ZONE RESISTORS is disabled, all zones other than Supervised Fire and Gas will not use an end-of-line
resistor. In this configuration, all zones switches (other than Supervised Fire and Gas) must be normally closed (open for alarm).
If any zone requires a normally open (closed for alarm) switch (other than Supervised Fire and Gas), the Setup item ZONE
RESISTORS must be set to "Yes" and all zones will require and external 1000-ohm end-of-line resistor.
The zone type for each zone is selected through the OmniLT SETUP menu on the console or by using the PC ACCESS software.
The system supports a maximum zone resistance, excluding the end-of-line resistor, of 150 ohms. The default setting for ZONE
RESISTORS is "Yes". The default settings for all zone inputs on an OmniLT controller are configured as Auxiliary inputs.
BURGLAR ZONE HOOKUPS
The OmniLT system supports both normally open and normally closed switches. Most contacts designed for doors, windows,
motion detectors, glassbreak detectors and other security devices meet this requirement. An external 1000-ohm end-of-line
resistor must be used for all zones if ZONE RESISTORS is set to "Yes".
When ZONE RESISTORS are set to "No", only normally closed switches can be used.
1.
When using a normally open switch, a 1000-ohm end-of-line resistor must be in parallel with the zone being used. Maximum
loop resistance excluding end-of-line resistor should not exceed 150 ohms. ZONE RESISTORS must be set to "Yes".
2.
When using a normally closed switch, a 1000-ohm end-of-line resistor must be put in series with the zone being used if
ZONE RESISTORS are set to "Yes". If ZONE RESISTORS are set to "No", the 1000-ohm end-of-line resistor is not used.
Maximum loop resistance excluding end-of-line resistor should not exceed 150 ohms.
3.
Power motion detectors from AUX 12V.
4.
Unused zones may be left open, and should be left at the default setting of AUXILIARY zone types.
5.
When Zone 8 is configured to anything other than a Supervised Fire or Gas zone, the Zone 8 Jumper (J9) should be set to the
NRM (normal) position.
