1.0 Introduction

These manual fire alarm call points have been 

designed for use in flammable atmospheres and harsh 

environmental conditions. The GRP enclosures are 

suitable for use offshore or onshore where light weight 

combined with a high level of corrosion resistance is 

required.
The units are available with the following options: 

Lift flap 

Resistors/Zener diodes (encapsulated) 

Test key facility

2.0 General safety messages and warnings

All instructions and safety messages in this manual must 

be followed to allow safe installation of the device. The 

device must only be installed and maintained by correctly 

trained site personnel/installers.

I.  To reduce the risk of ignition of hazardous 

atmospheres and shock, do not apply power to the 

device until installation has been completed and the 

device is fully sealed and secured.

II.  To reduce the risk of ignition of hazardous 

atmospheres and shock, keep device tightly closed 

when the circuit is energised.

III.  Before removing the cover for installation or 

maintenance, ensure that the power to the device 

is isolated.

IV.  Following installation, test the device to ensure 

correct operation.

V.  Following installation ensure a copy of this manual is 

made available to all operating personnel.

VI.  When installing the device, requirements for 

selection, installation and operation should be 

referred to e.g. IEE Wiring Regulations and the 

‘National Electrical Code’ in North America. Additional 

national and/or local requirements may also apply.

VII.  Cable termination should be in accordance with 

specification applying to the required application. 

MEDC recommends that all cables and cores should 

be correctly identified. Please refer to the wiring 

diagram provided with the unit.

VIII. Ensure that only the correct listed or certified cable 

glands are used and that the assembly is shrouded 

and correctly earthed.

IX.  Ensure that only the correct listed or certified stopping 

plugs are used to blank off unused gland entry points 

and that the NEMA/IP rating of the unit is maintained.

X.  MEDC recommend the use of a sealing compound 

such as HYLOMAR PL32 on the threads of all glands 

and stopping plugs in order to maintain the IP rating 

of the unit.

XI.  The internal earth terminal, where fitted, must be 

used for the equipment grounding and the external 

terminal, if available, is for a supplementary bonding 

connection where local codes or authorities permit or 

require such a connection.

XII.  When installing the device, MEDC recommends the 

use of stainless steel fasteners. Ensure that all nuts, 

bolts and fixings are secure.

XIII. A suitable sealing washer must be fitted to all glands 

and stopping plugs fitted into the enclosure.

XIV. The end user or installer shall ensure that this 

equipment is protected against external influences 

which could adversely affect the explosion protection, 

or contact the manufacturer if in doubt of the 

suitability of this equipment in the environment in 

which it is to be installed.

3.0 Installation

General

The unit should be mounted on a vertical surface using 

the four off Ø6mm fixing holes in the base. These have 

been designed to accept an M5 screw or bolt. Note, the 

cover assembly needs to be removed to access the unit 

fixing holes.
MEDC recommend the use of stainless steel screws.

Access to terminals

Unscrew the 4 off M5 screws (4.0mm A/F hexagon key) 

holding the lid to the base. The cover screws are captive 

and should be retained in the cover.

Gently remove the cover assembly from the base of the 

enclosure. The cover assembly should remain attached to 

the base by means of a retaining strap.

Once termination is complete, carefully replace the 

cover assembly back onto the base avoiding damage to 

the mating surfaces. Ensure that the retaining strap and 

wires are not trapped between the mating surfaces and 

that the o-ring is correctly seated in its groove. Ensure 

the retaining strap and wires are clear of the microswitch 

actuator and operating mechanism. Tighten the 4 off 

M5 screws (4.0mm A/F hexagon key) in the cover 

assembly evenly. To maintain the IP rating of the unit, the 

recommended torque on the cover screws is between 

2.5 - 3.0Nm.
