Technical Manual: EVC-H - 000014 (Changes are subject to DCRN)
Section 5 - INSTALLATION
In normal use, the
EVC-H
detector will be installed at
ceiling level. Pass field wiring through cable hole in
centre of base from rear of base. Offer up and affix
base to the ceiling or conduit fitting with screws via the
base mounting holes. Connect field wiring to base
terminals as detailed in below section ‘Connections’,
making sure that wiring will not obstruct fitting of detector
head. Fit detector head by inserting into base and
turning clockwise until notch in detector rim aligns with the
sensoris undertaken. At commissioning, the dust
cover should be removed and discarded.
NOTE: THE PLASTIC DUST COVER MUST BE REMOVED FROM THE
SENSOR IN ORDER FOR THE SENSOR TO FUNCTION CORRECTLY.
Section 6 - CONNECTIONS
Connections are made to the detector base. The connections
used depend on the type of base and the functions required.
See Section 4 ‘Base Models’, to identify the required type
of base and functions supported.
See below Figures 2, 3 & 4 for wiring to the detector’s base:-
