5.2  Features List 
 
Tough welded mild steel enclosures with high quality paint finish. 
Removable gland-plate for termination and looming. 
Optional door stay available for all panels except T1204A1, 
T1204A2, T1204DC. 
Temperature-compensated battery 
charging 
Battery charging voltage is automatically adjusted between 
28.25 and 26.72V DC over an ambient temperature range of 
-10°C to +55°C. 
Protects the battery from permanent damage due to deep 
discharge by automatically disconnecting it when the battery 
voltage falls below 21V. 
Mains Failed Indication Delay 
The indication of main power failure is delayed by 90 seconds to 
allow the power to be switched from ship to shore and vice versa 
without generating a false fault indication. 
Total power failure warning on the fire 
panels 
A separate, non-rechargeable 9V battery provides the power for 
an audible warning should the primary [ship’s] supply and the 
panel’s standby battery fail (or be disconnected). 
Operates all sounders for up to 5 seconds  without giving any 
panel indications (this is a land-based feature). 
Configurable detection zones 
Simple and flexible configuration process  utilising the LED 
display, allowing detection zones to be configured for any or all 
of the following: 
•  Latching or non-latching Fire indication. 
•  Normal or Intrinsically-Safe zone monitoring. 
•  Machinery Space Zones. 
Factory configuration: Latching, standard [non-I.S.], no zones 
programmed as Machinery Space Zones. 
Selectable Zonal or General Alarm 
Sounder operation with sounders in alert 
or silent in non-alarm zones 
Selectable via DIL switches on the motherboard. 
The standard sounders on the T1204 panel can be used in 
General or Zonal modes. [On T1216-C  and T1232-C  panels 
these sounders always operate in General mode regardless of 
DIL switch setting]. 
The output expansion system provides additional sounder 
circuits for General or Zonal use on the T1216-C and T1232-C 
panels. 
General sounder operation continuous or 
pulsed 
DIL switch selectable on the motherboard. All sounders operate 
continuously or pulsed as selected. 
Restart sounders or restart sounder delay 
DIL switch selectable on the motherboard. With the panel in the 
silence alarms condition, a 2
nd
  zone fire condition restarts the 
sounder delay or immediately operates  all sounders.  [This is 
available only when panel is configured to the Crew Alarm 
Mode.]
