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 sufcient push-on
terminals and then check for the specied voltage at the battery terminals
