Powering Up Access Control Systems

If an access control system involves more than a single door, a single power supply won't suffice.

Power supplies are an important part of any electrical access or security system. The power requirements for an access control system are therefore typically divided into two categories: power for the controls/readers and power for the locks. In reality, the power is used for several purposes...

StrikeIt™ will operate up to two 24VDC panic hardware devices simultaneously. It is designed to handle the high current surge that panic hardware locking devices demand. A programmable timed lock release feature ranging from one to 30 seconds, supervised lock outputs and two programmable fire alarm disconnect options are all included, along with simultaneous 12VDC and 24VDC constant power outputs for access control accessories. Two form “C” follower relays and two form “C” delayed momentary relays which follow the lock outputs are provided for activation of automatic door operators. On-board circuitry facilitates stand-by battery charging.

Honeywell Power Products

HPP’s Access Control Power Supplies offer significantly expanded capabilities. The core supplies, HP300ULX, HP400ULX and HP600ULX, are available in three power output levels: 2.5A, 4A and 6A. By adding the HPMOM5 fire door controller to the supply family, the HP300ULM, HP400ULM and HP600ULM Series complete the power supply package.

Adding the HPACM8 access control card to the base supplies makes the HP600ULACM8 capable of powering the most demanding applications. This power supply family has a wide range of applications for access control systems that require door control with additional power.

HPP Access Control Power Supplies carry both UL and ULC ratings for fire, access control and intrusion systems and have a large enclosure to ease wiring. They feature circuit-breaker battery protection, AC input and DC output LED diagnostic indicators, AC fail and battery monitoring contacts to aid in supervision, and a built-in charger for sealed lead-acid or gel-type batteries. In addition, the Power Supplies offer a filtered and electronically regulated output, and an automatic switchover to standby battery when AC fails. All of the power supplies are 12vdc or 24vdc field- selectable.

The HPP HPS312CX is a switching power supply/charger that converts low-voltage AC input into 6, 12 or 24VDC at 3.0A of continuous supply current. The HPS312CX also comes kitted with an HPP HPT2450 plug-in transformer, a 5 AH battery, a steel enclosure, and connecting hardware. This general-purpose power supply has a wide range of applications for access control systems that require additional power, and will operate with a non-linear power source.
