HOCHIKI M ARINE APPROVED ESP SENS OR RANGE
INSTALLATION INS TRUCTIONS

Products Covered: ALG-EM, ACB-EM, YBN-R/3M, YBO-R/SCIM
Introduction

The analogue Sensors listed above use a Common Mount ing Base (YBN-R/ 3M ) , which is electronics free, and the Shor t­Circuit Isolator B ase (YBO-R/SCI M ). The ACB-E polli ng LE D c an be turned off at t he Control Panel ( Control Panel
compatibility needs to be checked to verify if this fac ility is supported). Foll ow the guidelines bel ow before instal lation
and maint enanc e. Hochiki cannot guarantee a sensor’s performance if t hese gui delines are not followed.

Caution

Hochiki Mari ne Approved ESP Range of Sensors cannot be used to prevent fire itself, they are only intended t o det ect
certain c har ac teristi c s of fire. The ACB-EM sensor is used to detect c onditions and changes in temperat ur e and c annot
detect smok e and other phenomena. When install ing the sensor, check t hat the location of each one has been planned
according t o appr opr iate fire regul ations or recommendations. Please note t hat the ACB-EM M ulti- Heat Sensor default
mode is optical/heat, if thi s sensor is to be programmed to change modes i.e.: - opt ical t o heat then the ACB- E M shoul d
be spaced as a standard Heat Sensor. The sensor and base combi nation should be i nstalled to t he following guidel ines:

 Ensure the Sensor and Base are both installed i n ac c or 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

(-10°C to +70°C for A CB - E M ) and where the c ondensation and moisture levels are bet ween 10% to 95% RH –
Non-condensing (at 40°C).

 Only i nst all in sui table environments, the following should be avoided.

 Situations in which condensation exists.
 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-R/SCIM ) .

Certain actions can cause permanent damage to t he sensor. If the sensor i s subjected to any of the f ollowing it should
not be used:

 Disassembly and re-assembly.
 Impact or shock.
 Touching the thermistor (ACB-EM Heat sensor only).

If damage is suspected after a fire has occurred, the sensor should be replaced. A fter installation, all sensors on the fire
alarm system should be tested t o c onfir m correct operation. Install ation and m aintenance should only be carri ed out by
suitably trained engineer s. S ensor operation should not be tested with a naked flam e or open fire. Operation 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 vi sits. This period should be outl ined in the
appropriate standar ds or rec ommendations. If there are no such standards existing, Hochiki recommend that t he
minimum period of maintenance should be 1 year and that the following 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 incl uded wi th the sensor to prevent contamination during installation. 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 installation plan that shows the proper
locati on for each sensor, find the addr ess for the sensor to be installed. Check that the address and locat ion on the plan
match correctly . Address is any number from 1 to 127. For address setting, use the address programmer and write the
number on the label of the sensor after setting. When changing addresses, renew the number on the label. See the
TCH-B100 device address programmer instructi ons for f ur ther details of the addr ess setting method.

Wiring and Head Locking Mechanism

The bases should be wired as shown in Fig 2 below.
The ESP Marine Approved Range of Sensors can
also be locked ont o the relevant base by remov ing a
plastic lug on the underside of the sensor, please
refer to Fig 1. The Sensor can then be remov ed by
using a special Remov al Tool ( TSC-A100/ALG),
which is available from Hochik i Europe (UK) Ltd.
