HOCHIKI ADDRESSABLE CALL POINT
Products covered: HCP-E, HCP-E/Y, HCP-E(DPS), HCP-E(SCI), HCP-EO(SCI)
IMPORTANT: These call points are suitable for use only with the particular class of system for which they are
intended. These units are only compatible with the Enhanced Systems Protocol (ESP) and are for indoor use
only. Important Note – The use of lubricants, cleaning solvents or petroleum based products should be
SETTING THE ESP LOOP ADDRESS
Ensure that each device has a unique address set before operation. Note the address can be set before or
after connection to the loop but the loop MUST NOT be powered. The address is set by connecting a hand held
programmer (TCH-B100) to the programming connector on the reverse of the call point (top left corner) using a
PL-3 programming lead. Plug the square connector of the PL-3 on to the programming connector on the call
point, note the connector is NOT polarised (see fig 4). Set the address in the usual way (see the TCH-B100
Instructions for further details). Once the address is stored remove the programming lead.
The call point incorporates an LED mounted on the front cover which is continuously lit red when the device is
operated. The HCP-E(SCI) incorporates a bi-coloured LED; the LED will show amber when a short-circuit is
present but will switch to red when the unit is operated.
The polling mode of the call point (whether the call point will flash intermittently when connected to the loop) is
controlled via the connected control panel (check control panel compatibility). Note that factory default for all
models is flashing mode.
MOUNTING / CONNECTION
Flush Mounting: All units will fit onto any standard UK single switch/socket box having 60mm horizontal fixing
centres and a recommended minimum depth of 25mm.
Surface Mounting: Two styles of plastic back box are available for surface mounting, the SR for use with the
HCP-E, HCP-E/Y, HCP-E(SCI), HCP-EO(SCI) and HCP-EM and the SR-1T for use with the HCP-E(DPS) which
features a cable screen terminal.
If the unit is to be surface mounted, fix the plastic back box to the fixing surface using the four screw holes
provided (do not over tighten). A larger round hole is provided for loop cable entry. Before mounting the call
point to the back box, use the test key to unlock the lower cover (see fig 1). Remove the lower cover by sliding
downwards (see fig 2). Remove the non-frangible element to reveal the back box screw holes (see fig 3).
For surface or flush mounting, wire the unit to the loop cables using the terminal blocks, note these blocks
can be removed for easier connection (see fig 4). Wire the loop cables as per the wiring diagrams shown
below (see figs 5 and 6). The loop connections must not be greater than 2.5mm
cable diameter for proper
fixing to the terminal blocks. Once connected, fix the call point to the back box with the long black screws
