HOCHIKI ESP SENSOR & BASE RANGE
INSTALLATION INSTRUCTIONS

Products Covered: ALG-E, ALG-E(NP), ALG-EN, ALG-ENM / AIE-E,
AIE-E(NP) / ACA-E / ACB-E, ACB-EM, ACB-EW / YBN-R/3, YBN-R/3M

Introduction

The analogue Sensors listed abov e c an all use a Common Mounting Base (YBN-R/3 or Y B N- R/3M in the c ase of marine
approved sensors), which is el ectronics free, the Base Sounder (YBO-BS), the Base Sounder Beacon (YBO-BSB) and
the Short Ci rcuit I sol ator Bases (YBO-R/ S CI or YBO-R/SCIM i n the case of marine approved sensors) except the ACB­EW, which utilises flying leads. Please note t hat a sensor suffixed by NP is a non-pulsing ty pe and the LED’s will not
flash when polled, but the LED’s will illuminate when the sensor is in a fire c ondition. The ACA-E, ACB-E, A CB - E M ,
ALG-EN, A LG-ENM and ACB-E W polling LE D c an be turned off at t he Control Panel (Control P anel compatibility needs
to be checked to verify if this facility is supported). F ollow the guidelines below bef or e install ation and m aintenance.
Hochiki cannot guarantee a sensor’s perfor mance if these guidelines are not foll owed.

Caution

Hochiki ESP range sensors cannot be used to prevent fire itself, they are only intended t o det ect a certain characteri stic
of fire. The ACA-E (Heat mode only) , ACB-E, A CB -EM and ACB-EW sensors are used to detect c onditions and changes
in tem perature and cannot det ect smoke and ot her phenomena. When insta lling the sensor, check that the location of
each one has been planned accordi ng to appropriat e fir e r egulations or rec ommendations. Pl ease note that the ACA- E
Multi -Sensor default mode is optical /heat, i f this sensor is to be programmed to change m odes i.e.: - optical to heat then
the ACA-E should be spaced as a standard Heat S ensor.

The sensor and base combination should be installed to t he following guidelines:

 Ensure the Sensor and Base are instal led in accor danc e with Local St andar ds or Regulations.
 Sensor and Base combinations should only be install ed where ambient t emperatures are bet ween -10°C to +50°C

and where the condensation and m oisture level s are bet ween 10% to 95% RH – Non-c ondensi ng ( at 40°C).

 Only i nst all in suitable envir onments, the following should be avoided.

 Situations in which condensation exist s.
 Situations in which corr osi ve gases exist.
 Situations in which dust or steam exists.
 Situations in which obstacles exist, whic h c ould impede airflow to the sensor.
 Hazardous areas.

 Do not use a high voltage t ester on any Sensor or any Base with electronics (YBO-BS, YBO-BSB, YBO-R/SCI &

YBO-R/SCIM).

Certain actions can cause permanent damage to the sensor. If the sensor is subjected to any of the foll owing it should
not be used:

 Disassembly and re-assembly.
 Impact or shock.
 Touching the thermistor (ACB-E , ACB-EM, A CB - E W) Heat sensors and ACA-E Multi-Sensor only) .

If damage is suspected after a fire has occurred, the sensor should be replaced. After install ation, all sensors on the fire
alarm system should be tested t o c onfir m correct operation. Installation and maintenance shoul d only be carried out by
suitably trained engineers. Sensor operation shoul d not be tested with a naked flame or open f ire. Oper ation should
only be checked by equipment that is capabl e of ex c eeding the requi r ed detection threshold.

The sensor must be subject to periodi c maint enanc e dur ing regular servi c e visits. This period should be outlined in the
appropriate standar ds or rec ommendations. If there are no such standards existing, Hochiki recommend that the
minimum period of maintenance should be 1 year and that the followi ng shoul d be taken into ac c ount:

 A regular operation test should be per formed.
 A visual check for staining and mechanical damage should be made.

A dust cov er is included with the sensor to prevent contamination duri ng install ation. The dust cover must be removed
for the sensor to operate.

Setting the Address

Each sensor must have its address set befor e system operati on. Using the inst allation plan that shows the proper
locati on for each sensor, find the address for the sensor to be installed. Chec k that the address and locat ion on the plan
match correctly. Address is any number from 1 to 127. For addr ess setti ng, use the address programmer and write the

2-3-0-246/ISS10/NOV09

number on the label of the sensor after set ting. When address changing, renew the number on t he label. See the
instruction of t he appropriate address programmer TCH-B100 about detail of setting method. Not e that to program the
ACB-EW with the TCH-B100 address programmer, a progr amming lead (PL- 2) must be used (jack plug to croc- c lips).

Wiring and Head Locking Mechanism

The bases should be wired as shown in figure 1
below. Note that the ACB-EW features flying leads
for connection to t he loop and is supplied wi th its
own fix ing base. The ESP range of Sensors can
also be locked ont o the relevant bases by rem ovi ng
a plastic lug on the underside of the sensor, please
refer to fi gur e 1. The Sensor can then only be
removed by using a special removal tool, whic h is
available from Hochiki Europe (UK) Lt d.
