1. GENERAL

The HE-PSU(4.0) is a combined power supply and battery charger desi gned to be used for fire alarm control
and indicating equipment complying wit h EN54-2 and EN54-4.

2. POWER REQUIREMENTS

The HE-PSU(4.0) r equires a mains power supply of 230V AC. The maximum input curr ent is 2 Amps.
Mains frequency 50Hz.

2.1 HE-PSU(4.0) Input/Output Electrical Ratings

Input – 230V AC
Load output - 19V DC min (battery at minimum), 30 V DC max (mains on) max current 2.5 Amps + 1.5A

for batter y charging.
Maximum rippl e 800 millivolts

Battery charging output - 26.4 VDC (at 40°C) 28.9 V DC (at -5°C) 1. 5 Amps.
Fault signal s - switched negative open collector (with respect to load positive) current limi ted 100mA max.

Mains fail
Battery disconnected (Low battery shut off v oltage - 19 V (+/ - 1 volt) )
Battery low (Low battery warni ng voltage - 21 V (+/- 1 volt))
Earth fault
Charger fault (high output to battery)
Fail safe (any one of t he abov e)

These outputs are protected against short ci r c uits.

2.2 Fuse Ratings

Input fuse - T2A L250V. Replace only with a fuse of the same type.
Load fuse - self-resetting polyfuse 4 Amp rated. (Not replaceable).
RPSM fuse- Glass antisurge fuse 4A; BS4265

2.3 Batteries

Rechargeable, seal ed lead acid Yuasa NP or equivalent. Maximum capacity 17 Ah, minimum capacity 7Ah.
Maximum current consumption from battery – 4A.
Quiescent cur r ent in mains failure mode - 30 mA.

3. INSTALL ATION

This product shoul d be installed, commissioned and maintained by trained service personnel in accordanc e
with the following:

 (i) IEE regulations for electrical equipm ent in buildings
 (ii) Codes of practic e
 Statutor y requirements
 Any instructions specifically adv ised by the manufacturer

3.1 Environmental Considerations

The operati ng temper ature range should not exceed - 5°C t o +40° C (±2° ) .
Humidity lev els should not ex c eed 96% ( non- c ondensing).

3.2 Mounting

The HE-PSU(4.0) is supplied as an enclosure in portrait orientation with the terminal block to the left. The
requirement s of E N60950 r egar ding creepage, clearance, m ar king and segregation must be tak en into
considerati on and the power supply should remain accessible for fuse replacement and to access screw
terminal c onnec tions.

The equipment i s of Class1 construct ion so must be permanentl y and reliably connected to the fixed earth of
the installation.

The primary earth of the end use application must be perm anently marked with the protective earth symbol
(IEC415 No. 5017). A suitable primary disconnecting dev ice must be provided in the end use application.

Battery and load c onnec tions must be considered for connection to SELV (safety extr a low v oltage) ci r c uits
only.

The maximum leakage c ur r ent of the completed and installed equi pm ent must not exc eed 3.5mA..
