APPLICATIONS
(For all applications ensure that for multizone systems, doors only operate as and when required - consult your Local Fire Authority).
These applications are offered as suggestions only. The final method used must be determined by qualified personnel in the light of the
relevant local regulations, requirements and conditions. Therefore this company can accept no liability for problems that may
arise from the use of these suggested applications.
Fire Alarm system provides an isolated
contact that opens on alarm.

NOTE.
For the operation of relays consult the alarm manufacturer for details of polarisation and suppression of relays (these items if required
must be fitted by the system installer).
ACTION TO BE TAKEN SHOULD A FUSE RUPTURE
1. Turn off mains power.
2. Carry out the details given in the “Commissioning” section.

COMMISSIONING SYSTEMS INCORPORATING FSR UNITS
Before applying mains power.
1. Remove the secondary fuse.
2. Measure the load resistance presented to the output of the unit and ensure that it is NOT BELOW that stated in the Summary of
FSR Units.
3. Apply mains power and monitor the output current, ensuring that it is NOT GREATER than that given in the Summary of FSR
Units.
4. Refit the fuse and continue commissioning the remainder of the system.
To Fire Stays
NOTE.
DO NOT “WIRE” THE FUSE HOLDER. ALWAYS REPLACE THE RUPTURED FUSE WITH ONE OF THE CORRECT RATING.
RELAYS
The relays are optional extras. If one is required there is provision to fit one in each FSR unit, for which the base and volts-free
terminals are provided. When ordering the relays please quote a) Coil voltage required
b) FSR type number
NOTE.
Relay coils and terminals are independent and must be connected to supplies as required.
For 240V ac operation of the relay coil, an interface module FS3 is required, as well as a 24V dc relay for that particular FSR unit.
The module FS3 is slipped onto the connector PL: 1 and held in place using the small self tapping screw.
The 24V dc relay is plugged into the standard relay socket.
The 240V ac supply used for the relay operation is connected into the terminals “ L.N. MAINS COIL”. In this instance do NOT use the
terminals “RELAY COIL 48 V MAX”, (this is connected internally in this application).
FIG. 2
CAUTION: NEVER connect 240V ac supplies to any terminals other than:
1. L.N MAINS COIL
2. E.L.N. MAINS
Finally NEVER allow broken or loose 240V ac leads to track onto 24V dc terminals or connections.

FIG. 5
In the interest of continued development the company reserves the right to change the specifications of items detailed, without notice.
Always consult local authorities and the alarm manufacturers before adding any extra circuits to the existing alarm circuit, as there may
be problems with Zone Controls and the termination of devices. If after full consultation, circuits are to be added, these may need to be
terminated to allow full correct operation of the alarm system. As there are many variations of terminations no facilities are available
within the FSR unit to fit polarising diodes, suppression diodes, etc. These must be fitted at either the terminals of the FSR unit or at the
point of connection into the alarm circuit.
