DMP XF6 - Zones; Zone Response Time

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 dierent 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.
