a master fire alarm control panel via a two-wire serial bus. Each unit may contain one or two independent
XT+modules, as shown. Up to 15 modules can be connected to an Elite RSpanel, model number VF0850-xx or
VF0860-xx, firmware V07.02.005A (for Apollo) or greater or V07.02.005H (for Hochiki) or greater.
As shown in the image, the entire cabinet and everything contained within is referred to as a "unit". The individual
releasing modules and power supply are referred to as "modules".
Fascia
This section describes the featuresof the XT+ that are located on the fascia.

Power Supply
The XT+ uses a 5.25 Amp power supply, capable of charging batteries with capacities ranging from 7 to 60 Ah
and providing an output voltage of 24V and accepting input voltages of 120 VAC or 240 VAC. A jumper
connection for the 5.25 Amp power supply is set at the factory according to input voltage requirements of the
customer, either 120VAC or 240 VAC.

Features
Features of the power supplies include:
Features Description
Deep Discharge
Prevention
Prevents deep-discharge of the standby batteries by disconnecting the load when the standby bat-
tery-voltage drops below 19 +/- 1V DC. A deep-discharge can cause permanent damage to standby
batteries. Preventing this condition allows standby batteries to recharge for continued operation
after extended power outages.
Battery Backup Provides battery power to the load when the AC input of the power supply falls below the rated
level. The voltage at the load remains within the specified range during these switching-transitions.
Battery Boost Boosts standby battery voltage to maintain a constant 22 VDC when the voltage drops below the 22
VDC level.
Short-Circuit Protection Provides a shut down on the load side of the power supply when the load-current exceeds the max-
imum level.
Automatic Retry Restores output to the load when operating conditions return to nominal levels. This feature
restores voltage levels at the load following conditions such as over-current and AC restore.
Battery Impedance Provides a warning when the impedance of the battery reaches a level that could prevent proper
system operation.
Battery Supervision Battery presence and low battery voltage supervision
Earth Fault Detection Earth Fault Detection
General Trouble Relay All troubles are reported over the common trouble contacts.
Batteries
Standby Battery Type Two 12 VDC, valve-regulated lead acid
Standby Battery Charging Two standby batteries wired in series
Maximum Amp Hour Capacity 60 AH maximum
Charge Current 1.25 A Max
Output Current 4 A Max
Maximum Alarm Current 4A
Normal Standby Load during AC Fail
XT+ 1 Area Releasing Control Unit: 140mA
XT+ 2 Area Releasing Control Unit: 230mA
XT+ 2 Area Releasing Control Unit w/ Status unit & Ancillary board for each Area: 372 mA
A 12Ah battery can support a full alarm load (4A) for 7 minutes following 24hr standby
with a max standby load of 379mA.
Standby Operating Time 24 Hours
Battery Charge Voltage 27.6 VDC
Recommended battery size is 12 Ah for a typical configuration. Required battery size is mainly dependent on
standby current. To determine the most appropriate battery size, use the battery calculator in LE2.

If your required battery capacity exceeds the space available in the cabinet, an appropriately-sized auxiliary UL
listed battery cabinet suitable for fire alarm service will be required. If needed, install that cabinet (wired close-
nippled) adjacent to the unit to minimize battery lead length.

XT+ Releasing Control Unit Installation Manual

Preparing for Installation
1. Refer to the checklist provided above before beginning the installation process. For detailed information,
refer to the appropriate, referenced section in this document.
2. Select a suitable operation environment. The site should be clean, dry, and not subject to shock or vibra-
tion. Ensure that the environment is free from wire ends, knockout tabs, and other debris.
3. Familiarize yourself with the unit and components.
Item Description
Power Supply The XT+will have a 5.25 A power supply.
Ground Cable(s) Ground cabling is green and yellow, insulated wire containing connecting lugs. Ground cabling
provides common electrical grounds of the cabinet to the door.
4. The following items are not included, but may be required for the installation:
lTwo 12 VDC VRLA (Valve-Regulated Lead Acid) Standby Batteries - Required
lMounting Hardware - Mounting hardware that secures the cabinet to the wall is not provided. Screws
should be either a #10 or #12.
lA Ground Strap is required for handling circuit boards.
lVarious Diodes and Resistors: S2027 - 6.8k Ohm Resistor, S2028 - 10k Ohm Resistor, S2029 - EOL
Diode, S2051 - 470 Ohm Trigger Resistor
Mounting the XT+ Unit
IMPORTANT! Electronic components within the unit are vulnerable to damage from electrostatic discharge.
Ground straps must be worn by installers before handling circuit boards to prevent damage from electrostatic
discharge.
Mount the cabinet box on a flat, dry surface. Use the cabinet box as a template and mark the position of the
mounting holes while ensuring that the wall is flat at the chosen location. The unit must be mounted in an
accessible location. It must not be mounted in another enclosure or near sources of excessive heat. The unit is
intended for indoor, dry use only. Use knockout tabs of the cabinet box to route external cabling into the unit.
IMPORTANT! Drilling additional holes in the cabinet will void the product warranty.

Removing Cabinet Components
Remove the door, fascia, and power supply before mounting the cabinet box. To remove these components:
1. Disconnect all wires and cables between the door/fascia and the cabinet.
2. Remove the hinge pins of the fascia and then remove it from the cabinet box. Return the hinge pins to the
hinges of the cabinet box for safekeeping.
3. Remove the hinge pins of the door. Return the two hinge pins to the hinges of the cabinet box for safe-
keeping.
4. Disconnect the power supply and remove it from the cabinet.
5. Mark hole locations on the wall for mounting the empty cabinet.
6. Drill holes and anchor the empty cabinet box to the wall using appropriate mounting hardware to secure
it.
7. Remove the necessary number of knockout tabs from the cabinet box and feed external cabling into the
unit.
WARNING! Separate high and low voltage wiring in the enclosure with a minimum gap of 0.25". Do not route low
voltage cabling through the same conduit as AClines. ACpower lines should be threaded through a dedicated
conduit.
Replacing Cabinet Components
1. Replace the power supply.
2. Replace the door and fascia.
3. Reconnect the cabling.
4. Install the standby batteries.
Installing the Power Supply
The XT+ is equipped with a 5.25 Amp power supply. Set DIP switches on the power supply before completing
the installation process. Refer to DIP Switch Settings. The power supply settings must be performed to
establish the optimal charge current of the standby batteries. These power supplies can be set to operate at

inputs of 120 VAC or 240 VAC. For more information about the power supplies and their functions, see
Section 1: Power Supplies.
The power supply contains a jumper setting for changing from 120 VAC to 240 VAC. Check the jumper setting
prior to wiring and operating the 5.25 Amp Power Supply.
WARNING! Remove jumper J1 before operating the unit at 240 VAC. Failure to remove jumper J1 prior to
operation will cause permanent damage to the power supply.
Confirm that the 5.25 Amp Power Supply is set for 240 VAC before operating. Permanent damage of the
power supply will result if the 120 VAC jumper setting exists while operating the power supply at 240 VAC.
High voltage is present on jumper pins. Remove ACpower before changing jumper setting.
