Xtralis VESDA VPS-VEA-115UL User manual

Operation
TThe Xtralis Model VPS-VEA-115UL and VPS-VEA-230UL are power supplies that convert a 120VAC / 60Hz or
230VAC / 50Hz respectively input to 24VDC nominal output (see specications). They are intended for use in applications
requiring UL Listing for Fire Protective Signaling. The units must be installed in accordance with the National Electric Code
(NFPA70), the National Fire Code (NFPA72), and all other applicable local codes necessary for compliance with the local
authority having jurisdiction.
Space is provided in the VPS-VEA-115UL and VPS-VEA-230UL power supply cabinet for up to two 12V / 35AH or
36AH batteries (congured for 24V). For a larger standby capacity in a single VESDA-E VEA installation or when more than
one VESDA-E VEA detector is to be powered, use model VEA-BAT battery enclosure to house up to two 12V / 35AH or
36AH batteries or use a UL1481, ULC-S527 or UL864 Listed enclosure.
Operation Overview
The VPS-VEA-115UL and VPS-VEA-230UL is a power supply intended to power the VESDA-E VEA Detector Base
Unit plus up to two (2) VESDA-E VEA Detector Stacks (see battery table). A power failure indication is provided via a
dry relay contact (Form C) which transfers due to:
1. AC input loss,
2. a low AC input voltage,
3. a loss of battery voltage,
4. a short circuit of the battery leads or
5. a short circuit of any of the DC power outputs.
Refer to the wiring diagram located on the VEA unit for proper connections.
Note: The screw terminals can accommodate up to two wires each, provided the wires sit under the terminal
clamp on opposite sides of the screw.

Part: 30739
Installation Instructions
Mounting: 1. Using the four mounting holes in the rear of the enclosure as a template, mark the four
holes on the required mounting surface,
2. Drill holes in mounting surface to allow installation of appropriate fasteners,
3. Using appropriate fasteners, secure the VEA enclosure to the mounting surface,
4. Locate and install all required wiring conduit(s) following installation design
documentation.
Wires: Connect the AC power source to a dedicated 120VAC for VPS-VEA-115UL or 230VAC for
VPS-VEA-230UL branch circuit.
Note: Connect ground wire to ying green lead.
Use 14AWG minimum. This circuit is supervised. For battery and DC output power
connections, use 18AWG minimum. The battery circuit is supervised. Use 22AWG minimum
for the power supply trouble signaling output. This circuit is dependent on the equipment it is
connected to for power limited classi cation
Note: Keep power-limited wiring (Common Trouble wiring), separate from non power-
limited wiring (AC input DC Output & Battery). Use minimum 0.25” spacing.
Supervision: To report loss of AC power, DC output circuit fault or low/no battery condition, connect wiring
to the appropriate trouble contact terminals and to a supervised initiating device circuit of a
re alarm control unit, a monitoring module of an addressable signaling line circuit or other
independently powered trouble indicating device.
Note: In normal operation (non fault), the Common trouble reporting relay is energized.
Contact nomenclature (N.C., COM, N.O.) are shownfor normal state.
Battery hookup: In an installation using batteries external to the VPS-VEA-115UL/230UL power supply
cabinet, route the wiring to the batteries in conduit or equivalent.
Note: Place batteries in the enclosure with terminals facing the front.
Maintenance: The system should be tested for proper operation as required by NFPA72, the National Fire
Code, and your local authority having jurisdicton. Included in this system veri cation should
be the following tests.
Output voltage test: Under normal load conditions, the DC output voltage should be checked for proper voltage
level, (27V).
Battery test: To ensure a fully charged battery (batteries) and properly operating charging circuit, under
normal load conditions:
1. disconnect the 120/230VAC power source,
2. after 5 minutes, check for the speci ed voltage at the circuit terminals marked ‘BAT’,
(approx. 27V).
In multiple battery systems, isolate the battery pairs by disconnecting sufcient push-on
terminals and then check for the specied voltage at the battery terminals
