4.0 Standby Battery Requirements

Only use batteries recommend by Protec (see technical specification section). The charger has been

specifically designed to maintain the charge voltage at an optimum level for these batteries over the entire

operating temperature range in order to maximise the life of the batteries.

The charger is designed to charge batteries up to a maximum capacity of 24Ah to 80% of their capacity in 24

hours and 100% in 72 hours.

5.0 Cabling Requirements

Wiring should be installed in accordance with BS7671 or local wiring regulations and also with

BS5839 Part 1. The ECA recommended cable separation for Electromagnetic Compatibility in Buildings

must be followed.

A readily accessible double pole disconnection device is required to be installed external to the equipment,

and should be used only for the fire alarm system. Wiring from the disconnection device to the charger

should be in 1.5mm² fire rated cable with circuit protection rated at 5 Amps.

Mains and field wiring must be segregated by keeping the mains wiring as short as is feasible and by routing

it through one of the knockouts in the enclosure in the vicinity of the mains terminal block. The mains

terminal cable restraint provided must be used to retain the cable.

Field wiring must be wired in suitably sized, screened, fire rated cable. The cable should use the knockouts

to the left side of the enclosure and should not be routed anywhere near the mains wiring.

Although no connections are to be made to the power supply until the commissioning stage it is important

that cables are left long enough to connect directly to the relevant terminals. To ensure that cable tails are

left with sufficient length all cable tails must be a minimum of 500mm.

6.0 Installation Procedure

The 9100EN power supply may be surface or flush mounted (no extra bezel is required when flush

mounting).

The 9100EN circuit board is fully enclosed within a sealed control PCB housing. The control PCB housing

must never be opened. If the 9100EN requires repair it must be sent back to the Protec factory.

The batteries are fully accessible with the control PCB housing removed from the back box.

The 9100EN must be located internally in an area that is not subject to dampness, extremes of temperature

or physical abuse. The environmental limits are given in the technical specification section

6.1 Unpacking

Carefully open the cardboard carton (do not use a sharp object) and remove the packing fitments,

manuals and spares pack.

6.2 Removal of the Door

 Stage 1: Remove the 9100EN from the packaging then, using a T15 Torx® type security tool,

unscrew but do not withdraw the fixing screw from the bottom of the panel housing front as shown in

Fig. 6.0.

 Stage 2 and 3 : Slide the door upward from the bottom and pull away as shown in Fig. 6.0

Put all removed parts in a safe, dry place.

The 9100EN power supply is only suitable for install on permanent internal equipment.

Note: Further insulation tests MUST NOT be carried out after this point and the mains or standby supply

MUST NOT be connected.

Figure 6.0 Removing the 9100EN door

N93-597-00 Issue 1 Page 8 of 17 © Protec Fire Detection PLC 2014

6.3 Removal of the Control PCB Housing

Before handling the 9100EN power supply PCB housing it is important that any

operatives discharge themselves of any static charge that may have built up. This can

be done by momentarily touching a solid earth point (a non-painted part of a radiator,

for example).

The Power supply PCB housing is a sealed unit and must not be opened. Tampering

with this unit will invalidate the warranty. If the unit becomes faulty it must be

returned for repair.

Unscrew and remove the four mounting screws on the control PCB housing. Carefully lift away the

control PCB housing from the plastic enclosure. See Fig 6.1.

The 9100EN power supply PCB housing and all screws should be stored in the cardboard carton

away from the place of work where they will not get damaged.

6.4 Preparing the Mounting Position and Cable Entries

Use the dimensions shown on the interior rear face of the 9100EN back-box in conjunction with a

spirit level to mark out the fixing locations for the panel. Drill and plug the mounting holes just

marked.

Using a suitable tool carefully remove the rear panel knockouts at the required cable entry positions

and mount the enclosure in position whilst feeding the cables into the enclosure via suitable glands.

The mains cable entry position must be segregated from all other system cabling, a

reserved knock-out is provided specifically for this purpose.

A four way brass earth block is supplied with the 9100EN. Three locations are provided for this in the

9100EN back box. This allows the best location to be selected depending on wiring entry

requirements. Choose the location then clip the earth block into the back box, ensuring it is securely

fitted.

6.5 Installing the Standby Batteries

The 9100EN power supply is designed to house two 12V 3.3Ah Valve Regulated Lead Acid (VRLA)

batteries. These fit into the back-box and must be secured with the two plastic tie-wraps provided

as shown in figure 6.2.

Only use batteries supplied or recommended by Protec. The internal charger has been specifically

designed to maintain the charge voltage at an optimum level for these batteries over the entire

operating temperature range in order to maximise the life of the batteries.

6.6 Connecting the Standby Batteries

The two standby batteries must be connected in series with the battery link provided. Then,

observing correct polarity ( red lead to the positive of one battery and black lead to the negative of

the other battery ), carefully push the spade connectors of the 9100EN battery leads onto the

relevant battery terminals as illustrated in figure 6.3 .

Please note that at this point the 9100EN will not power up until the mains supply is connected.

Figure 6.3 Standby battery connections

6.7 Refitting the Control PCB Housing

Ensure that all cable earth connections are sleeved to insulate them and then securely connect them

to the brass earth terminals in the back-box.

Carefully route the battery leads from the rear of the control PCB housing down between the two

batteries.

Replace the Control PCB housing (a reversal of removal), ensuring it is pushed flush to the back box

and that the battery leads do not get trapped. Secure with the four screws removed previously,

taking care not to over tighten the screws.

6.8 Connecting the 24V output wiring

When connecting wiring from the fire alarm equipment to any other equipment, care must be taken

to avoid subjecting the fire alarm equipment to any hazardous voltages. This is normally achieved

by only connecting SELV circuits to the equipment, or by using optical or galvanic isolation.

The 24V output from the power supply are fed from the terminals marked '+24’ and ‘0V' on the main PCB

(TB2).

6.9 Connecting the global fault output wiring

Volt free global fault contacts are provided to allow optional connection to ancillary systems.

These connections are found on the PCB and are marked N/O, N/C and COM (TB4).

Under 'no fault' conditions the COM and N/C contacts are short circuit, and change to open circuit when the

PSU has detected a fault (including being completely depowered).

N93-597-00 Issue 1 Page 13 of 17 © Protec Fire Detection PLC 2014

6.10 Connecting the Mains Cabling

Isolate the incoming mains supply by ensuring the fused double pole isolator is in the

‘OFF’ position.

Pay particular attention that the incoming mains cable is segregated from all other

cables within the 9100EN enclosure.

Ensure the incoming earth cable is firmly connected to the Main PCB (see figure

6.4), and that the earth cable from the Main PCB is securely connected to the brass

earth terminals within the back-box.

The mains wiring must now be restrained using the clamp provided to secure the

mains cables to the control PCB housing (see figure 6.5). The restraining clamp must

be supported at the rear when the two screws are being tightened.

6.11 Re-fitting the Door

Before replacing the door, it is recommended these checks are made:

 Ensure the mains cable conductors are short and there is no bare conductor showing.

 Ensure the incoming mains earth is secure in the PCB terminal block.

 Ensure the mains cable is restrained by use of the cable clamp provided.

 Ensure all 24 Volt output supply, Global Fault contacts wiring has been completed and will not foul

the door when it is refitted.

Replace the plastic door by raising the door and placing flush to the back-box of the panel (figure 6.6

step 1). Slide the door down and ensure it pushes fully home into the back box (figure 6.6 step 2).

Finally screw in the fixing screw, taking care not to over tighten it (figure 6.6 step 3)

Figure 6.6 Refitting the 9100EN door

6.12 Switching the Mains Power On

Switch the fused isolator to the ‘ON’ position. The green ‘Power’ indicator will illuminate and,

assuming all other connections are correct, the 9100EN should show no fault on the display

7.0 Maintenance

No regular maintenance of the PSU is required. The internal microcontroller of the PSU performs regular

checks to ensure the battery and outputs are healthy.

However, the standby batteries should be checked periodically and, in any case, be replaced after 5 years

from the date of installation.
