---

M/s Pyrogaurd Engineers Pvt. Ltd.: ABORT SWITCH for TFAFSS- should be UL/FM/Vds/LPCB approved for safety and Reliability.

The Pull type Abort Switch should be prefer over Glass type Abort switch because if accidently or anyhow, glass is broken, the whole gas would be released.

The type of abort switch is left to the manufacturer.

M/s MX Systems International Pvt. Ltd.: We should add more point in abort switch as follows: If the abort switch is initiated before the automatic discharge delay expires, the system will prevent agent release and the automatic delay timer will stop. When the abort switch is restored, the automatic delay timer will resume from the stop point and agent release will occur with the expiration of the timer.

5.4 0.28 ALARM UNIT (AU):

---

M/s Ceasefire Industries Pvt. Ltd.: Clause 5.4 Alarm unit needs to be removed as it is not required for people to vacate in case of activation of ICAFSS. This provision is required mandatorily for TFAFSS only.

0.29 Clause 5.4.1.1 Modified as: The AU shall be provided for warning of hazardous condition.

5.4.1.1 The AU shall be provided for warning of hazardous condition. It shall provide audio & visual warning alarm for personnel evacuation prior to discharge.

M/s Supremex Equipments: In case of ICAFSS the pressure switch is activated after the system is discharged. In that case prior audio visual alarm is not possible. However alarm is received during discharge. Also since the gas is being released within cabinet, and also due to the fact that localized suppression cylinders are small, the quantity of gas involved is very less hence personnel evacuation is not required. However for the sake of their awareness we can certainly give an alarm during discharge.
