Zones - Digital Monitoring Products XF6 Series Installation And Programming Manual

ZONES

Terminals 17-28
Zones 1 to 6 (Terminals 17 to 28) on the panel are 24 VDC powered zones. For programming purposes, the zone numbers
are 1 through 6. See the Compliance Listing Guide (LT-2779) for a list of the compatible 2-wire smoke detectors. Do not
mix detectors from different manufacturers on the same zone.
Caution: Performing a Sensor Reset momentarily drops power to the devices on zones 1-6. The panel views these
zones as Open while power is absent.
When wiring powered zones for 2-wire smoke detectors, refer to the following specifications:
• Maximum wire length—3000 feet (18 AWG) or 1000 feet (22 AWG)
• Maximum voltage—28 VDC
Maximum normal standby current—7.5 mA DC
•
• Maximum line impedance—100 Ohms
• Maximum short circuit current—63 mA
The voltage sensing Terminal measures the voltage across a 3.3k Ohm EOL resistor to ground. Use Model 309 3.3k Ohm
resistors. Dry contact sensing devices can be used in series (normally-closed) or in parallel (normally-open).

Operational Parameters
Each protection zone detects three conditions: Open, Normal, and Short.
Zone Response Time
A condition must be present on a zone for 500 milliseconds before it is detected by the panel. Ensure detection devices
used on the protec tion zones are rated for use with this delay. Zones 1-6 can also be programmed for a fast response
delay of 160 milliseconds.
